This chapter describes steps you must follow and concepts you should understand before installing the Cisco Integrated Communications System 7750 (Cisco ICS 7750). The chapter includes the following sections:
Read the warnings in this section before installing the system. For translations of these and other warnings that appear in this guide, see "Regulatory Compliance and Safety Information."
Read the warnings in this section before installing or working on the system.
Warning Read the installation instructions before you connect the system to its power source. |
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 16A international) is used on the phase conductors (all current-carrying conductors). |
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. |
Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
Warning The device is designed to work with TN power systems. |
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic printed circuit cards are improperly handled. ESD can result in complete or intermittent failures. Always follow ESD-prevention procedures when removing and replacing cards and other system components:
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohms). |
Caution Static voltages as low as 30 volts can cause latent damage to circuitry. Be sure to observe all standard antistatic procedures when handling electronic equipment and components. For example, wear a grounding strap. |
Warning Do not operate the system unless all cards and faceplates are in place. Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. |
Follow these guidelines when working on equipment powered by electricity:
If an electrical accident occurs, proceed as follows:
Follow these guidelines when working with any equipment that is connected to telephone wiring or to other network cabling.
Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
Follow these guidelines when moving or lifting the chassis:
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Lift the unit only by using handles that are an integral part of the chassis, or by grasping the chassis underneath its lower edge. |
Warning Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your legs, not your back. |
As with any electrical or electronic equipment, EMI can be created by the operation of the equipment, and the equipment may be susceptible to EMI.
Protect the equipment against EMI to help ensure correct operation of the system. There should be no X-ray equipment, handheld transceivers, or microwave, radio, or television transmitters in the equipment room.
Strong EMI, especially when caused by lightning or nearby radio transmitters, can destroy the cards or other components in the Cisco ICS 7750 and can even create an electrical hazard by conducting power surges through power lines into installed equipment.
Note To prevent or remedy interference problems, you may need to consult electromagnetic compatibility (EMC) experts. |
If signal wires exceed recommended cabling distances, or if signal wires pass between buildings, you should give special consideration to the effect that a lightning strike in your vicinity might have on electrical equipment.
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can drive enough energy into conductors to damage or destroy electronic equipment. If you have experienced such problems, you should consult EMC experts to ensure that you have adequate electrical surge suppression and shielding of signal cables in your Cisco ICS 7750 operating environment.
This section describes requirements and considerations related to site where you intend to install the Cisco ICS 7750, as follows:
Before you begin to set up and cable your Cisco ICS 7750, be sure to adhere to these guidelines:
It is essential to properly cool all of the equipment in a rack-mounted system. The components of the system require an input air temperature below 40ºC (104ºF).
Four internal, DC-powered fans cool the system's drives, cards, and power supplies in the front of the chassis. The fans are housed in a front-accessible fan tray.
To avoid hazards associated with uneven mechanical loading of the rack, plan your installation so that the weight of the equipment is evenly distributed in the rack. Where possible (within the limitations of equipment and cabling), mount the heaviest units near the bottom of the rack.
The floor of the equipment room (the room where you intend to install the system) must support the combined weight of the system and all of the other equipment located in the equipment room. Consider the following when you choose flooring:
A correctly installed electrical system helps ensure personnel safety and reliable performance. This section provides an overview of the power and grounding requirements for the system.
The system must be correctly grounded before you connect power or install any processor cards. There is a grounding stud on the rear of the system chassis. See the "Grounding the System" section before connecting power or installing any subsystem cards.
Warning When installing the unit, the ground connection must always be made first and disconnected last. |
Power for the rack system must come from a dedicated circuit breaker. Do not plug any other electrical device into an outlet connected to the circuit breaker serving the rack equipment.
Caution Data loss can occur if the circuit is overloaded and the circuit breaker trips. |
Make sure that the circuit breakers that furnish power to the system are the correct size to protect the system. Verify that all receptacles are wired for 3-wire power distribution (hot, neutral, and ground).
All power receptacles servicing any equipment that is directly cable-connected to the system must have a single, common grounding point. The unshielded (ground) wire must be at true ground potential with a resistance (measured at the power panel bus) of 5 ohms or less between the bus bar and earth.
Power disruptions occur for a number of reasons, including faulty wiring, acts of nature, and power company outages. You need to plan your system installation so that equipment is protected from three types of power problems:
Consider the following guidelines when planning for and installing electrical equipment:
Note For additional information about backup power, see "Redundan t Power" later in this chapter. For information about installing and using backup power systems with the Cisco ICS 7750, refer to the User's Manual APC Smart-UPS or the Cisco RPS 300 Redundant Power System Hardware Installation Guide. |
Because power problems can vary in scale, careful planning is required to protect your system. Simple power problems include dislodged power cords, tripped circuit breakers, and local power supply failures.
Note You can take precautions against problems such as dislodged power cords, but these fall outside the scope of this publication. This section focuses on issues related to planning for large power outages. |
General power outages are usually more common than failures in a particular device's power system. Because some network topologies place key network applications in a centralized, corporate location, a large-scale power failure could result in lost revenue for every minute your network is downparticularly if your network carries voice and data traffic.
If power fails at a remote site, all connections to that remote site will be terminated unless they are otherwise protected. Generally, power failures in a remote office are more serious when network services are widely distributed. To protect against such failures, use a UPS.
When rack-mounting, mount the Cisco ICS 7750 chassis with the supplied bolts to ensure that there is a good electrical connection between the bolts and the mounting surface.
Caution Failure to observe proper grounding practices can result in noise, electrostatic discharge, and radio frequency interference (RFI) problems. |
The physical environment for storage, transport, and operation of the Cisco ICS 7750 must meet the specifications shown in the Cisco ICS 7750 System Description.
Do not store the system in an area subject to extreme variations in temperature or humidity. Extremely high and low temperatures can degrade system reliability. Low humidity can increase static electricity buildup, and high humidity can affect the performance of disks and printers.
In addition to temperature and humidity, the following environmental factors must be controlled in the area where the system is installed:
This section summarizes important considerations for installing power cords and cables.
The system chassis has one or two detachable AC power cords. Place the chassis within 6 feet of the electric receptacle.
Understanding and documenting the installed cable in your facility can help you plan for network scalability and availability and can also help you identify potential problems with your network.
Consider the following issues:
When planning cable installation, follow these guidelines:
Caution To avoid damaging equipment or components during cabling, unplug all other devices in the system before you begin with the installation of any additional units. |
The size of your network and the distances between network interface connections depend in part on the following factors:
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds and distances for purposes of signaling. You should use this information as a guideline in planning your network connections.
The maximum distances for Ethernet and Fast Ethernet network segments and connections depend on the type of transmission cable being used. The terms 10BaseT and 100BaseT are standard abbreviations for the following:
The maximum transmission distance between stations for Ethernet and Fast Ethernet connections that use Category 5 (100 Mbps) cables is 328 feet (100 meters).
Note If you intend to lay new cable, we recommend that you use Category 5 (100BaseT) or faster media. |
Serial signals travel a limited distance at any given baud ratethe slower the baud rate, the greater the distance that the signal can travel over the connection.
Table 2-1 shows the relationship between baud rate and distance for signals traveling over an Electronic Industries Alliance/Telecommunications Industry Association (EIA/TIA-232) serial connection.
To plan wire routing, establish the starting point and the termination point of each cable relative to the location of the terminal devices in the building. Then examine the construction of the building to determine the best wiring routes. Consider the following when you plan the wire routing:
Caution Data degradation can occur if wires travel near strong EMI sources. (See "Required Tools and Equipment" for additional information.) |
Cables can terminate at the following locations:
Tip Always keep a record of all termination point information. |
You need the following tools and parts to install and maintain the system. If you need additional equipment, contact a customer service representative for ordering information.
You need a PC (or laptop computer) to complete initial system configuration, to upload and install software bundles, and to perform system management tasks. The PC also needs to be physically near the ICS 7750 chassis, to allow for console (serial) and direct Ethernet connections.
Ensure that the PC meets the following requirements:
Note If you are using a USB keyboard with a USB mouse, you will need a pass-through USB port on the keyboard for connecting the mouse. Alternatively, you can use a USB hub, to which you can connect both the keyboard and mouse, and then connect to one of the USB ports on the SPE310 through the hub's uplink port. Either the pass-through USB port or a USB hub is needed because one of the two USB ports on the SPE310 card is needed for the CD-ROM drive. See the "Using USB Devices" section for more details on using USB devices. |

You should install the system for maximum data, voice, and power redundancy. Follow these guidelines to ensure system redundancy:
To more easily manage cables that are connected to the system, install the cards with the greatest number of connected cables as far left in the chassis as possible. For example, an MRP300 card with two 2-port WICs installed is best installed in slot 1. This prevents the cables that are connected to the card from obscuring the front panels of other cards.
The system is shipped with a cable management bracket. See the "Installing the Cable Management Bracket" section for instructions on how to install it.
Table 2-4 lists the number of cards that the Cisco ICS 7750 supports.
Card or Module | Chassis Slot | Minimum Required | Maximum Allowed |
