To remove a power supply:
1. If the ED-48000B is not operating during the replacement
procedure, skip to step 2.
If the ED-48000B is going to continue operating during the
replacement procedure, check the power LEDs to verify that the
minimum number of power supply units required is still
functioning: A fully populated ED-48000B requires a minimum of
one power supply unit in any slot at all times to ensure power to
the director. For maximum availability of the ED-48000B director,
you should have a minimum of one power supply unit in slot 1 or
3, and one in slot 2 or 4.
2. Push the locking tab toward the power supply unit and pull the
handle out and down.
