Same-Row Connections
Cable slack is 6 inches (15.25 cm) for a single cable in any enclosure.
Extra cable length allows cable to bend to attach to connector. If you are tying together
a large group of cables, you will need extra slack in each cable in that group. How
much slack you need depends on the size of that group of cables. For more
information, contact your service provider.
Same-Row Connections
To choose the correct ServerNet cable length for connecting two enclosures in the
same row:
1. Determine the arrangement of the two enclosures:
2. Note whether you are connecting an SEB to another SEB or to an IOMF CRU, and
refer to the appropriate table:
SEB-to-SEB Connections in Same Row on page B-4
SEB-to-IOMF CRU Connections in Same Row on page B-5
3. If the cables will be routed under a raised floor or overhead in cable troughs,
determine how much slack the cables must have.
4. Determine how many cables will be tied together with one cable tie at the back of
each enclosure.
If you will be tying together a large group of cables, you need extra slack in each
cable in that group. How much slack you need depends on the size of that group of
cables. For more information, contact your service provider.
5. Refer to Appendix A, Part Numbers. If no cable is exactly the length you need,
always chose the next longer cable.

Note. These illustrations do not differentiate between SEBs and IOMF CRUs; they show
only enclosure relationships and positioning.
Note. If you want to route the ServerNet cables beneath a raised floor rather than through
the cable channels on each enclosure, see Different-Row Connections
on page 7-9, which
gives information about calculating the additional cable length that this procedure requires.
