Figure 2-6 1 RU Distribution Shelf Installation
2.2.2.1 Install the Communications Cabling (Optional)
If the power system is equipped with the 1 RU Distribution Shelf, follow the instructions below. For
power systems without the 1 RU Distribution Shelf, skip this procedure and go to the “2.2.3 Install the
Ground Cable” procedure on page 2-9.
Intra-system shelf communication is accomplished using a 10 pin Molex™ connector originating from
the system shelf and connecting to the 1 RU Distribution Shelf. Use the following instructions to install
the communications cabling:
Step 1 Locate the distribution alarm cable at the rear of the system shelf.
Step 2 This cable is a prewired 10 pin Molex™ connector and is installed into the 1RU at the indicated location
(Figure 2-7).
Note The Molex™ alarm connector is keyed and can only be inserted one way. If the connector does
not insert easily into the mount, make certain that the connector is being inserted with the key
side up.
