Next steps
1. If you have removed the strain relief bar and bracket, replace them. For information about the strain relief bar and bracket, see the
Rail
Installation Guide

.
2. Connect the power cable to the PSU, and plug the cable into a power outlet.
CAUTION:
When connecting the power cable to the PSU, secure the cable to the PSU with the strap.
NOTE:
When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for the system to recognize the
PSU and determine its status. The PSU redundancy may not occur until discovery is complete. Wait until the new
PSU is discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify
that the PSU is functioning properly.
3. Follow the procedure listed in
After working inside your system
Wiring instructions for a DC power supply unit
Your system supports up to two –(48–60) V DC power supply units (PSUs).
NOTE:
For equipment using –(48–60) V DC power supply units (PSUs), a qualified electrician must perform all
connections to DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself.
All electrical wiring must comply with applicable local or national codes and practices. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow all safety instructions that came with the
product.
CAUTION:
Wire the unit with copper only, unless otherwise specified, use only 10 American Wire Gauge (AWG) wire
rated minimum 90ºC for source and return. Protect the –(48–60) V DC (1 wire) with a branch circuit over-current
protection rated 50 A for DC with a high interrupt current rating.
CAUTION:
Connect the equipment to a –(48–60) V DC supply source that is electrically isolated from the AC source
(reliably grounded –(48–60) V DC SELV source). Ensure that the –(48–60) V DC source is efficiently secured to earth
(ground).
NOTE:
A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field
wiring.
