Install The Grounding Wire; Connect The Switch To A Power Source - HP ProCurve 5400zl Installation And Getting Started Manual

6. Install the Grounding Wire

If a grounding wire is to be attached to the switch chassis, the grounding lug
must be removed and a wire crimped to it and the grounding lug must be
reinstalled.
1. Use a #1 Phillips (cross-head) screwdriver and remove the grounding lug
and two screws from the back of the switch.
2. Crimp the grounding lug to a properly grounded grounding wire.
3. Re-attach the grounding lug to the switch with the two screws.

7. Connect the Switch to a Power Source

1. Plug the included power cord into the switch's power connector and into
a nearby properly grounded AC power source.
If a redundant power source is available, it is desirable to power one
switch power supply from the regular AC source, and the other power
supply from the redundant AC source. This will provide redundancy in AC
power to the switch, as long as the switch PoE power usage falls within
the capability of one power supply. If both power supplies are plugged
into a common AC source, there is still power supply redundancy, that is,
protection against power supply failure, but if the AC source fails, the
switch will lose all power.
2. Re-check the LEDs during self test. See "LED Behavior" on
