Route 2U enclosure power cords
This basic task connects the supplied power cords to the redundant power cooling modules (PCMs) and then
to independent power distribution units (PDUs) that are connected to an uninterruptible power system. You
must only connect PDUs to a power source that has a safety electrical earth connection.
CAUTION Use only power cords supplied in the installation kit or those that meet product specifications.
CAUTION Adhere to power source and power connection requirements to avoid harm to equipment.
l
Only connect the power cooling module (PCM) to power sources that comply with product specifications
and labels.
l
Always remove all power connections before you remove a PCM from the storage or expansion enclosure.
To route 2U enclosure power cords:
1. Select both power cords from the packaging and remove the cable ties.
2. Facing the rear of the rack cabinet, connect a power cord connector to each PCM.
3. Route the left power cord below the left fan and connect the plug to an outlet on an independent PDU,
allowing a minimum of slack.
4. Route the left power cord below the right fan and connect the plug to an outlet on an independent PDU,
allowing a minimum of slack.
