Routing I/O Cables
Routing the cables is a significant task in the Superdome installation process. It is important not only for the
immediate need of completing the installation, but efficient cable routing is important when future service
calls are made.
Neatness counts. The most efficient use of space is to route cables so that they are not crossed or tangled.
Figure 3-34 Routing I/O Cables
Use the following procedure and guidelines to route cables through the cable groomer at the bottom rear of
the cabinet.
Step 1. Remove the cable access plate at the bottom of the groomer.
Step 2. Beginning at the front of the cabinet, route the cables using the following pattern:
1. Route the first cable on the left side of the left-most card cage first. Route it under the
Peripheral Controller Interface (PCI) card cage toward the back of the cabinet and down
through the first slot at the right of the cable groomer.
2. Route the second cable on the left side of the left-most card cage to the right of the first cable,
and so on, until you complete routing all of the cables in the card cage.
The number and width of cables vary from system to system. Use your judgement and the
customer’s present and estimated future needs to determine how many cables should be routed
through each cable groomer slot.
3. After you route the left most card cage at the front of the cabinet, route the cables in right-most
card cage at the back of the cabinet. Begin with the right cable in the card cage and work
toward the left.
