 |
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. |
The Cisco 6100 with NI-1 system fits in a 23-inch wide rack. See Table 7-2 for individual rack space requirements.
| Component | Rack Space | Height | Depth |
|---|---|---|---|
Cisco 6100 chassis | 9 RUs1 | 15.75 in. (40.00 cm) | 12 in. (30.48 cm) |
POTS splitter
| 4 RUs | 7 in. (17.78 cm) | 12 in. (30.48 cm) |
Fan tray2 | 2 RUs | 3.5 in. (8.89 cm) | 12 in. (30.48 cm) |
| 1RU = rack unit. One RU is equal to 1.75 inches (4.45 cm). 2Leave 1 RU of space under the fan tray. This space allows for the intake plenum and for cabling back to front for the OC-3c NI-1 module. |
The central office (CO) power source or rectifier supplies external power to the system as -48 VDC from the fuse and alarm panel. Power connections from the fuse and alarm panel are wired separately to the Cisco 6100 chassis and the fan tray. Connections for single- and dual-power feeds are provided. The power input connections are redundant, and only one is absolutely necessary for system operation. The nominal voltage is -48 VDC; the minimum operating value is -36 VDC; and the maximum operating value is -60 VDC.
Before you connect the system to a power source, verify that the power source is properly grounded and it falls within the internal power supply rating.
Depending on your configuration type, calculate the typical power required for each Cisco 6100 Series component. After you calculate the typical power, determine the minimum fuse value for each component that is wired to the fuse and alarm panel. Use Table 7-3 to calculate the minimum fuse rating that is necessary for each of your Cisco 6100 with NI-1 system components.
|
Note The power rating label that is supplied on the rear of each chassis and fan tray indicates the maximum fuse value for the chassis or the fan tray. |
