Connecting the Power Shelf to the Chassis
1
Connect each (female) DB-25 cable connector to a (male) connector port on the rear panel of the power
shelf. Be careful not to bend the connector pins. Secure each connection by tightening the connector’s
captive screws.

Next, connect each (male) DB-25 cable connector to a (female) connector port on rear panel of the
switch chassis. Be careful not to bend the connector pins. Secure each connection by tightening the
connector’s captive screws.
Recommendation.
When installing the PoE connector cables, plug each cable into the corresponding
connector on both the power shelf and the switch chassis. For example, if a cable is connected to the far-
left connector on the power shelf, connect the cable to the far-left connector on the switch chassis. In addi-
tion to facilitating a clean, manageable cable installation, this will ensure that the cable lengths will
accommodate most chassis installations.
