Warning 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.

Warning High-performance devices on this card can get hot during operation. To remove the card, hold it by the faceplate and bottom edge. Allow the card to cool before touching any other part of it or before placing it in an antistatic bag.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.

2.1.2 Maintaining Safety with Electricity

Follow these guidelines when working on equipment that is powered by electricity:

•

Locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.

•

Disconnect all power by removing the fuses from the fuse and alarm panel before:

•

Never assume that power is disconnected from a circuit; always check the circuit.

•

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

–

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

–

Determine if the person needs rescue breathing or external cardiac compressions; then, take appropriate action.

2.1.3 Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Use an antistatic strap when you handle any card or component.

•

Always use an ESD ankle or wrist strap and ensure that the wrist strap makes good skin contact.

•

Connect the equipment end of the strap to the ESD jack on the front left side of the chassis, as shown in Figure 2-1.

•

When you install a component, use available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help ensure that bus connectors are properly seated.

•

When you remove a component, use available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

•

Handle the I/O card by the edges only; avoid touching the printed circuit boards or connectors.

•

Avoid touching the printed circuit boards or connectors on the NI-2 cards or line cards.

•

Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

•

Avoid contact between the printed circuit boards and clothing. The wrist strap protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

2.1.4 General Maintenance Guidelines

2.1.4.1 Hot Swapping Cards

Hot swapping allows you to remove and replace cards without disconnecting the system power. The Cisco 6160 chassis supports hot swapping for the following cards:

•

Quad-port flexi ATU-C (4xflexi), quad-port STU-C (4xSDSL), octal-port DMT ATU-C (8xDMT), octal-port ITU-C (8xIDSL), and octal-port G.SHDSL SHTU-C (8xG.SHDSL) line cards—When the system detects that you have added or removed a line card, it automatically runs diagnostic and discovery routines and acknowledges the presence or absence of the line card. If you remove and replace a line card with one of the same type, the newly installed line card receives the same provisioning as the original card. The system resumes operation without any operator intervention.

Note

Hot swapping line cards interrupts service for the subscribers assigned to that line card.

•

DS3+T1/E1 IMA, DS3/2DS3, OC-3c/2DS3, or OC-3c/OC-3c NI-2 cards—Hot swapping active NI-2 cards interrupts service for the entire system until the NI-2 card is replaced or until a redundant NI-2 takes over system operations. However, you can hot swap standby NI-2 cards without interrupting service.

2.1.4.2 Hot Swapping Blower Trays and PEMs

The following sections detail the hot swapping guidelines for the blower tray and power entry module (PEM).

2.1.4.2.1 Blower Trays

The blower tray supports hot swapping. Hot swapping allows you to remove the blower tray without disconnecting the system power. You do not need to power down the Cisco 6160 to replace the blower tray. However, if you must remove the blower tray from an operating Cisco 6160, replace it within five minutes. If that is not possible, power down the system to avoid thermal damage.

2.1.4.2.2 PEMs

The PEM is not hot swappable if there is only one PEM installed in the chassis. If you remove the only operating PEM from the chassis, power down the system before you begin. Removing the only operating PEM from the chassis will interrupt service for the entire system until you replace the PEM.

The PEM is hot swappable if there is a secondary PEM installed in the chassis. If the active PEM is removed, the standby PEM becomes the active PEM and the system continues to operate.

2.1.4.3 Installation and Replacement Suggestions

The following examples list recommended installation and replacement practices for the Cisco 6160 system cards.

•

Do not force the line card into its slot. This action can damage the pins on the backplane if they are not aligned properly with the line card.

•

Ensure that the line card is straight and not at an angle when you install the line card in the slot. Installing the line card at an angle can damage the line card. Use the guide rails to install the line card correctly.

•

Fully depress the ejector tabs to ensure that the line card connector mates with the backplane correctly. Firmly seat the line card in the slot.

•

Do not force the I/O card onto the chassis connectors. Ensure that the I/O card is straight and parallel to the chassis when you install the module onto the connectors. The pins on the connectors can be damaged if the I/O card is not installed correctly.

•

Firmly press on the I/O card to ensure that the connectors mate with the chassis correctly.

2.2 Site Requirements

This section describes requirements for the site at which the Cisco 6160 system is to be installed. Before you install the Cisco 6160 system, ensure that all the criteria in this section are met. This section includes the following information:

2.2.1 Environmental Requirements

Proper operation of the Cisco 6160 system depends on a proper environment. Before you install the Cisco 6160 system, ensure that all the criteria in this section are met. This section describes the following environmental requirements:

2.2.1.1 Temperature, Altitude, and Humidity

The Cisco 6160 system can tolerate a wide range of temperatures. Table 2-1 provides the Cisco recommendations for temperature, altitude, and humidity conditions in a central office (CO) environment.

Table 2-1 CO Operating Environment Requirements
Environmental Specifications	Description
Temperature Altitude Humidity	41 to 104�F (5 to 40�C)—Operating 23 to 131�F (-5 to 55�C)—Short-term operating -197 to 13,124 feet (-60 to 4,000 meters) 5 to 90% (noncondensing)

Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104�F (40�C).

2.2.1.2 Ventilation

•

Chassis placement—Leave one rack unit (RU) under each Cisco 6160 chassis for cabling needs and the intake plenum.

•

Blower tray installation—A blower tray must be installed in the Cisco 6160 chassis.

•

POTS splitter location—POTS splitters do not dissipate heat and should be positioned at the bottom of the rack.

The main air intake vents are located at the bottom front of the chassis, as indicated in Figure 2-2. The intake vent for each PEM is located at the bottom of the PEM front panel. All air exhaust vents are located on the rear of the chassis at the top. Do not obstruct the intake and exhaust vents in any way.

2.2.1.3 Space

You can install a combination of these Cisco 6160 system components in a standard seven-foot rack:

•

Third-party POTS splitter—Required in a Cisco 6160 with POTS splitter configuration.

Depending on your configuration type, plan accordingly so that the CO rack accommodates your needs. Use Table 2-2 to calculate the rack space necessary for your Cisco 6160 system configuration. The total amount of rack space should not exceed 42 RUs. If your total configuration exceeds 42 RUs, either replan your configuration or use more than one rack to house the Cisco 6160 system components.

Table 2-2 Rack Space Calculation for Cisco 6160 System Configurations
Line	Instructions	Calculation
Cisco 6160 with a POTS Splitter Configuration
1	Total number of Cisco 6160 chassis in the rack—Maximum is three chassis per rack (include subtending host and subtended node chassis)
2	Total number of third-party POTS splitters in the rack
3	Number of RUs required for each POTS splitter¹
4	Multiply line 2 by line 3 to determine the total POTS splitter space requirement
5	Multiply 11 RUs by the total number of Cisco 6160 chassis on line 1
6	Multiply 1 RU by the total number of Cisco 6160 chassis on line 1²
7	Add lines 4 through 6 to obtain the total number of RUs needed for a Cisco 6160 with a POTS splitter configuration.
Cisco 6160 Without a POTS Splitter Configuration
8	Total number of Cisco 6160 chassis in the rack—Maximum is three chassis per rack (include subtending host and subtended node chassis)
9	Multiply 11 RUs by the total number of Cisco 6160 chassis on line 8
10	Multiply 1 RU by the total number of Cisco 6160 chassis on line 82
11	Add lines 9 and 10 to obtain the total number of RUs needed for a Cisco 6160 without a POTS splitter configuration.

¹See the documentation that accompanied the third-party POTS splitter to determine the number of RUs required. One RU is equal to 1.75 inches (4.45 cm.).

²One RU is recommended for cabling needs and the intake plenum.

2.2.2 Power Requirements

The CO power source or rectifier supplies external power to the system as -48VDC from the fuse and alarm panel. The nominal voltage is -48VDC, the minimum operating value is -40.5VDC, and the maximum operating value is -75VDC

Power connections from the fuse and alarm panel are wired to the power terminal block connectors on the Cisco 6160 backplane. The power terminal block connectors are located behind each corresponding PEM. The PWR 1 terminal block connector is for the primary PEM and the PWR 2 terminal block connector is for the secondary (redundant) PEM. Only one power connection is necessary for system operation.

Note Before you connect the system to a power source, verify that the power source is properly grounded and that it falls within the internal power supply rating.

The typical power required for your Cisco 6160 system will depend on your configuration type. Use Table 2-3 to calculate the power required for each of the Cisco 6160 system components and the total power required for the system.

Warning Only a DC power source that is isolated from AC mains with reinforced insulation, and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd Edition, EN 60950, and IEC950, can be connected to a Cisco 6160 system. This requirement ensures that in a catastrophic power source fault condition, hazardous voltages are not present on power terminals and connectors.

Table 2-3 Power Calculation for the Cisco 6160 System
Step	Instructions	Calculation
1	If you are using 8xIDSLs, multiply 5.5W by the total number of 8xIDSLs installed in the chassis.
2	If you are using 8xG.SHDSLs, multiply 16.5W by the total number of 8xG.SHDSLs installed in the chassis.
3	If you are using 8xDMTs, multiply 24W by the total number of 8xDMTs installed in the chassis.
4	If you are using 4xSDSLs, multiply 9W by the total number of 4xSDSLs installed in the chassis.
5	If you are using 4xflexis in G.lite mode, multiply 13W by the total number of 4xflexis (G.lite mode) installed in the chassis.
6	If you are using 4xflexis in DMT mode, multiply 17.5W by the total number of 4xflexis (DMT mode) installed in the chassis.
7	If you are using 4xflexis in CAP mode, multiply 13.5W by the total number of 4xflexis (CAP mode) installed in the chassis.
8	Multiply 33.5W by the number of NI-2 cards installed in the chassis.
9	Enter 60W for the PEM. Add 6W if a second PEM is installed in the chassis.
10	Enter 104W for the fan tray.
11	Add lines 1 through 10. This is the typical power required for the Cisco 6160.

2.2.3 Rack-Mounting Requirements

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

—This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

—When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

—If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

We recommend that you mount the Cisco 6160 system in a rack. Ensure that vertical hole spacing on the rack rails meets standard EIA-310-C requirements—1 inch (2.54 cm) spacing. All portions of the rack should be equal to or less than the NEBS maximum allowances of 12 inches (30.48 cm) in depth.

When you install the Cisco 6160 system in a rack, be sure to allow enough room to access the backplane of the unit for wiring and cabling purposes. The majority of the Cisco 6160 connectors are located on the backplane.
