3 Connecting the main rack to the
expansion rack
You can complete the connection between the main and expansion racks while the controllers are
powered on (online) or off (offline). The offline method is preferred if downtime is available.

Routing cables in the expansion rack

NOTE:
The cables used are 5m multi-mode OM3 LC/LC fiber channel cables supplied in the AP712A kit.
Route the cables along the side of each rack so they can be secured and kept out of the way.
Route all of the expansion cables as a single bundle out of the bottom of the expansion rack.
Route the cables underneath the suspended flooring, if present.
Bring the cables into the top or bottom of the main rack and separate them into two bundles.
Wrap the excess cables around the spools that are provided in the expansion accessory kit.
CAUTION:
Do not allow fiber cables to bend with a radius smaller than 30 mm (1.2 in). Overbending
compromises the integrity of the glass fiber transmission. To avoid deforming or possibly breaking
copper cables, do not allow them to bend with a radius smaller than 60 mm (2.4 in).
