Cabling common equipment
To secure network group cables with tie-wraps, follow these instructions:
1 Tie-wrap to the Core 0 strain relief bracket, all Core 0 CNI to 3PE cables
and Core 1 CNI to 3PE cables for groups 0 and 1. The strain relief bracket
is located at the bottom of the right-hand-side I/O panel of the Core 0
Module, as viewed from the rear of the module.
2 Tie-wrap to the Core 1 strain relief bracket, Core 1 CNI to 3PE cables for
network groups 2, 3, and 4. The strain relief bracket is located at the
bottom of the right-hand-side I/O panel of the Core 1 Module, as viewed
from the rear of the module.
Option 81C is a dual CPU system with standby processing capabilities, fully
redundant memory, and up to five full network groups. Option 81C is
equipped with two redundant disk drive units.
The following modules are required:
— two Core/Net Modules (houses CPU and one network group)
— one InterGroup Module
— a minimum of two Network Modules (provides one additional network
group)
— a minimum of one IPE Module
Additional Network and IPE Modules are required for additional network
groups. PE Modules, RPE Modules, and application modules can also be used.
Note: The terminating plugs in the InterGroup Module for unused
connectors are pre-installed in the factory. These should be removed only
when additional groups are installed. Remove a plug just before the
connector is installed for a new group and installed a plug immediately
after a cable is disconnected when a group is removed.
Figure 83 shows a typical configuration for five full network groups.
Additional columns can be added, and there can be more than one row of
columns.
