AC Power Supply and Fan Operability Test
Once your power supplies and fan trays are installed, verify their operability by supplying power to the
chassis and verifying the status LEDs.
Before you begin this power test, inspect your equipment rack and chassis. Verify that:
• Each Power Supply is properly installed and plugged into the assigned slot.
• The AC-cord Retainer is secured over the plugs.
• Your power cables connect to an appropriate AC power supply in a manner that complies with your
local electrical codes. For AC systems, a Main Disconnect must be provided for each AC cord.
3. Slide the power supplies into their slots until the module front is flush with the shelf front.

4. Connect the Power Supply cord to the designated socket (Figure 11).
5. Re-install the AC-cord Retainer by tilting approximately 15
o
and gently sliding in the long edge just above
the AC cords.
6. Secure the retainer by tighten the locking screws on either side of the retainer.
Danger: Leakage Current (High Touch Current) in AC-powered systems: AC power cords are
secured to the power inlet using the provided brackets. The power cord plugs must be secured to
the building outlets by the qualified chassis installer or a qualified electrician.
Danger: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this
system without the AC-cord Retainer.
