InRow Half-Rack RC Installation24

Feeds A and B. The equipment is capable of receiving power through one of two separate feeds, feed

A or feed B. Use the display interface to configure the unit to receive power through feed A, feed B, or

both). If connected, feed B is the primary power input to the equipment by default; feed A is the backup

power input. The equipment receives power through feed B regardless of whether feed A is receiving

power. If power is removed from feed B, feed A takes over and supplies power to the equipment (if feed

A is connected). Connect the feed A and feed B cables to individual, breaker-controlled branch circuits

or to PDUs backed by separate Uninterruptible Power Supplies (UPSs).

Note: Feed A and feed B must not use the same branch circuit, PDU, or UPS.

For more information on configuring power input feeds, see the InRow RC Operation and

Maintenance manual.
