This chapter describes requirements and considerations for installing the Cisco 6100 hardware.
When installing the 6100 chassis in a Central Office (CO) rack, be sure to allow enough room to access the backplane on the rear of the unit for wiring/cabling purposes. The majority of the connectors are located on the back. Also be sure to leave a 1U space between the multiplexer chassis (MC) and the first line concentration chassis (LCC) or POTS splitter chassis (PSC), depending on your configuration, for pass through cables to the connector on the front of the OC3 network interface (NI) module.
The PSCs dissipate the least amount of heat and should be located at the bottom of the rack no matter which configuration is used.
The following cautions and warnings should be adhered to in order to ensure a safe and hazard-free installation.
 | Warning Maintenance should be performed by trained service personnel who are aware of the potential hazards involved; for example, fire, and electric shock. |
 | Caution Proper electrostatic discharge (ESD) protection is required at all times when handling modules. Installation and maintenance personnel should be properly grounded via ground straps to eliminate the risk of ESD damage when handling modules. Modules are subject to ESD damage upon removal from their anti-static shipment bag. |
| Warning Never install telephone wiring during an electrical storm. |
| Caution Ensure that the temperature of the room is within operating parameters to ensure adequate cooling. See the "Specifications" appendix for operating specifications. |
The following sections discuss space, power, and environmental requirements for the Cisco 6100 system installation.
A 7-foot relay rack can contain a combination of the following:
The 6100 is designed to fit in a 23-inch wide relay rack. Allow enough space for wiring purposes. See the following table for individual rack space requirements.
| Chassis | Chassis Height | Chassis Depth |
|---|---|---|
MC | 15.75 in | 12.00 in |
LCC | 7.00 in | 12.00 in |
PSC | 7.00 in | 12.00 in |
Before you connect the unit to a power source, verify that the power source is properly grounded and falls within the internal power supply rating. The internal power supply rating for the MC is 364 watts maximum. The internal power supply rating for the LCC is 36 watts maximum.
External power is supplied to the system as -48VDC from the CO power distribution frame to the fuse/alarm panel. Power connections from the fuse/alarm panel are wired separately to the MC and each LCC. Connections for dual -48VDC feeds are provided. The power inputs are redundant, and only one is absolutely necessary for system operation. The nominal voltage is -48VDC, while the minimum and maximum operating ranges are -36 to -60VDC.
See the "Connecting Power from the MC and LCC to the Fuse/Alarm Panel" section and the "Applying Power to the System" section for more information on power and fusing.
The following table lists the environmental operating ranges for CO and remote terminal applications.
| Environmental Specifications | Description |
|---|---|
Central Office Bellcore | 5 to 40º C operating temperature |
Remote Terminal Bellcore | - 40 to 65º C operating temperature |
The Cisco 6100 has no internal user-serviceable parts. However, modules may be added or removed without removing power from the system using an ejector tab on the faceplace of the module.
A 3/16" flat-blade screwdriver and a Phillips-head screwdriver are required for installing or removing a chassis in the relay rack.
The following subsections discuss the connectors on the rear panel of each chassis. See the "Cables and Connector Pinouts" appendix for detailed pinouts for all the 6100 connectors.
Figure 4-1 shows the rear panel of the MC. Table 4-3 describes the connectors on the rear panel.
