Note To ensure that your Cisco IOS software release supports your hardware, see the "New and Changed Information" section on page vii. Also refer to the "Hardware Supported" section of the latest release notes for the Cisco ONS 15530.
Before Installing
Before you install the Cisco ONS 15530, you must complete the following tasks:
•Unpack and inspect the shelf.
•Maintain a network record.
•Assemble required tools and equipment.
•Mount the shelf.
Caution Use extreme care when removing or installing connectors so you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
Unpacking and Inspecting the Shelf
The Cisco ONS 15530 comes with the standard mounting set. The shelf is thoroughly inspected before shipment. If any damage has occurred during transportation or if any item is missing, notify your Cisco customer service representative immediately.
Upon receipt, inspect the equipment as follows:
Step 1 Take inventory.
Compare the equipment inside with the packing slip and the equipment list provided by customer service. If there are any discrepancies, notify the Customer Service Center.
Step 2 Check for external damage.
Visually check all components and immediately report any shipping damage to your customer service representative. Have the following information ready:
•Invoice number of shipper (see packing slip)
•Model and serial number of the damaged unit
•Description of damage
•Effect of damage on the installation
Keep a record of all of your hardware, configuration options, and network settings.
Mounting the Shelf
The unit is designed for rack-mounting in a cabinet rack. Use star-type lock washers on the rack screws to ensure a good conductive connection between the chassis and the rack. For information about installing the units in a customer cabinet, see the instructions from the cabinet manufacturer.
Chassis-Lifting Guidelines
The fully configured system weighs approximately 71 pounds. The chassis is not intended to be moved frequently. Before you install the system, ensure that your site is properly prepared so you can avoid having to move the chassis later to accommodate power sources and network connections.
Two or more people are required to lift the chassis. Each time you lift the chassis or any heavy object, follow these guidelines:
•Never attempt to lift the chassis by yourself. Because of the size and weight of the chassis, use at least two people to safely lift and move it without causing injury or damaging the equipment.
•Ensure that your footing is solid, and balance the weight of the chassis between your feet.
•Lift the chassis slowly; never move suddenly or twist your body as you lift.
•Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your back muscles.
•Do not remove installed components from the chassis.
•Always disconnect all external cables before lifting or moving the chassis.
To safely lift the chassis, follow these steps:
Warning Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back.
Step 1 Each person should stand on either side of the chassis, and place one hand under the air intake at the bottom front of the chassis.
Step 2 With the other hand, grasp the handle on the chassis and carefully lift the chassis as shown in Figure 2-1 and Figure 2-2.

Figure 2-2 Lifting the Cisco ONS 15530 CHAS-N
Rack-Mounting the Shelf
Rack-mounting the shelf is the preferred method of installation for the Cisco ONS 15530. This section gives general rack-mount installation guidelines and explains how to install the rack-mount and cable-management brackets on the Cisco ONS 15530 for the following types of installations:
• General Rack-Mount Installation Guidelines
• Flush-Mounting the Cisco ONS 15530 CHAS-N in a 19-Inch Rack
• Flush-Mounting the Cisco ONS 15530 CHAS-E in a 21-Inch Rack
General Rack-Mount Installation Guidelines
When planning your rack-mount installation, consider the following guidelines:
•Allow a minimum of 11 rack units (17.7 inches or 45.0 cm) of vertical rack space for the Cisco ONS 15530 CHAS-E chassis with the air ramp baffle. The Cisco ONS 15530 CHAS-N chassis requires a minimum of 9 rack units (15.7 inches or 39.9 cm) of vertical rack space. Measure the proposed rack location before mounting the chassis in the rack.
Note The Cisco ONS 15530 CHAS-E chassis cannot be installed in a 19-inch rack.
•Check for obstructions (such as a power strip) that could impair rack-mount installation before using a particular rack. If a power strip does impair a rack-mount installation, remove the power strip before installing the chassis, and then replace it after the chassis is installed.
•Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving line cards, connecting cables, or replacing or upgrading components). Otherwise, allow 19 inches (48.3 cm) of clearance to remove FRUs (field replaceable units).
•Maintain a minimum clearance of 3 inches (7.62 cm) on the front, top, and sides of the chassis for the cooling air inlet and exhaust ports, respectively. Avoid placing the chassis in an overly congested rack or directly next to another equipment rack; otherwise, the heated exhaust air from other equipment can enter the inlet air vents and cause an over temperature condition inside the chassis.
Caution To prevent chassis overheating, never install a Cisco ONS 15530 in an enclosed rack or room that is not properly ventilated or air conditioned.
Caution Always install the air ramp baffle below the Cisco ONS 15530 CHAS-E.
•Always install heavier equipment in the lower half of a rack to maintain a low center of gravity to prevent the rack from falling over.
•Install and use the cable-management brackets included with the Cisco ONS 15530 to keep cables organized and out of the way of the line cards and CPU switch modules. Ensure that cables from other equipment already installed in the rack do not impair access to the line cards, or require you to disconnect cables unnecessarily to perform equipment maintenance or upgrades.
•Install rack stabilizers (if available) before you mount the chassis.
•Provide an adequate chassis ground (earth) connection for your chassis.
Flush-Mounting the Cisco ONS 15530 CHAS-N in a 19-Inch Rack

Preventing ESD Damage
Electrostatic discharge (ESD) damage occurs when electronic cards or components are mishandled and can result in complete or intermittent failures. Note the following guidelines before you install or service the system:
•Always wear an ESD-preventive wrist or ankle strap when handling electronic components. Connect one end of the strap to an ESD jack or an unpainted metal component on the system (such as a captive installation screw).
•Handle cards by the faceplates and edges only; avoid touching the printed circuit board and connector pins.
•Place any removed component on an antistatic surface or in a static shielding bag.
•Avoid contact between the cards and clothing. The wrist strap only protects the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Note For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Power Guidelines
Follow these precautions and recommendations when planning power connections to the Cisco ONS 15530:
•Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.
•Provide proper grounding to avoid damage from lightning and power surges.
Caution This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.
Note The Cisco ONS 15530 installation must comply with all applicable codes and is approved for use with copper conductors only. The ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis ground to a central office or other interior ground system should be made with a 6-AWG, copper ground conductor at a minimum.
Power Connection Guidelines for DC-Powered Systems
The DC-input power supply allows the Cisco ONS 15530 to operate at -48 VDC nominal in North America and -60 VDC in Europe.
See Appendix A, "Specifications," for system power specifications, including input voltage and operating frequency ranges.
Note The DC return is to remain isolated from the system frame and chassis (DC-I).
Warning A readily accessible disconnect device must be incorporated in the building's installation wiring.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a Listed and Certified fuse or circuit breaker, 25A minimum 60 VDC, is used on all current-carrying conductors.
Plant Wiring Guidelines
Following are guidelines for setting up the plant wiring and cabling at your site. When planning the location of the new system, consider the distance limitations for signaling, EMI, and connector compatibility, as described in the following sections.
Interference Considerations
When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:
•Bad wiring practice can result in radio interference emanating from the plant wiring.
•Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the Cisco ONS 15530.
Note To predict and remedy strong EMI, you may also need to consult experts in radio frequency interference (RFI).
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.
Cabling Guidelines
The size of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). For example, standard coaxial cable has a greater channel capacity than twisted-pair cabling. The distance and rate limits in the following descriptions are the IEEE recommended maximum speeds and distances for signaling; however, you can usually get good results at speeds and distances far greater than these. For example, the recommended maximum rate for V.35 is 2 Mbps, but it is commonly used at 4 Mbps without any problems. If you understand the electrical problems that might arise and can compensate for them, you should get good results with rates and distances greater than those shown here; however, do so at your own risk.
When preparing your site for network connections to the Cisco ONS 15530, you must consider a number of factors related to each type of interface:
•The type of cabling required for each type (fiber, thick or thin coaxial, foil twisted-pair, or unshielded twisted-pair cabling)
•Distance limitations for each signal type
•The specific cables you need to connect each interface
•Any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSUs), or data service units (DSUs)
Before you install the Cisco ONS 15530, have all additional external equipment and cables on hand. For ordering information, contact a customer service representative.
The extent of your network and the distances between network interface connections depend in part on the following factors:
•Signal type
•Signal speed
•Transmission medium
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds and distances for signaling purposes. Use this information as a guideline in planning your network connections prior to installing the Cisco ONS 15530.
Powering Up the Shelf
System power is supplied by redundant -48 VDC or by redundant 120-240 VAC power supplies located on the right side of the chassis. The Cisco ONS 15530 supports the use -48 VDC and 120-240 VAC power supplies used together to provide redundancy.
Connecting DC-Input Power
Warning A readily accessible disconnect device must be incorporated in the building's installation wiring.
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a Listed and Certified fuse or circuit breaker 25A, minimum 60 VDC, is used on all current-carrying conductors.
To apply DC-input power to your Cisco ONS 15530, follow these steps:
Step 1 Strip not more than 0.4 inches (10 mm) of insulation off the ends of the DC power leads (see Figure 2-24).
Figure 2-24 Stripping Insulation
Step 2 Connect the ground wire to the power supply ground terminal (see Figure 2-25).
Note The ground connections should always be connected first and disconnected last.
Step 3 Connect the positive DC power lead from the external power source to the positive (+) DC terminal (see Figure 2-25).
Figure 2-25 DC Power Supply
Step 4 Connect the negative DC power lead from the external power source to the negative (-) DC terminal (see Figure 2-25).
Step 5 If you are installing redundant DC power, repeat Step 3 and Step 4 on the second power supply, connecting to a second external power source.
Connecting AC-Input Power
The Cisco ONS 15530 can be powered directly from the facility VAC input through the Cisco ONS 15530 120-240 VAC power supply (see Figure 2-26). A retention clip secures the power cord to the power supply.

Note The AC power cord that connects to the Cisco ONS 15530 120-240 VAC power supply power cord and then to the building AC is not shipped with the Cisco ONS 15530. You must order this power cord separately.
The AC-input power supply differ in plug type; make sure you have the correct style for your site (see Figure 2-27 and Table 2-1.) All AC-input power supply power cords measure 8 feet (2.5 m). We recommend that you:
•Install an uninterruptable power source where possible.
•Install proper grounding to avoid damage from lightening and power surges (see the "Grounding the Shelf" section).

Installing and Removing the Power Supplies
To install an AC or DC power supply, follow these steps:
Step 1 Remove the power supply from its packaging.
Step 2 Grasp the power supply handle with one hand. Place your other hand underneath to support the bottom of the external power supply.
Step 3 Place the power supply correctly at the bay opening.
Step 4 Carefully slide the power supply into the bay. Make sure that the power supply is installed completely and that the faceplate is flush with the chassis.
Step 5 Secure the power supply installation by securing the captive installation screws at the top of the power supply.
To power on the chassis, see the "Powering Up the Shelf" section.
To remove an AC or DC power supply, follow these steps:
Step 1 Unplug the power cord on an AC power supply or remove the negative, positive, and ground connections from the DC power supply.
Note The ground connections should always be connected first and disconnected last.
Step 2 Unscrew the captive installation screws at the top of the power supply.
Step 3 Grasp the power supply handle with one hand and pull the power supply out of the bay. Place your other hand underneath to support the bottom of the external power supply.
