Installing the MX960 AC High-Capacity Power Supplies
Move the AC input switch in the chassis above the empty power supply slot to
the off (
O
) position.
Ensure that the release lever below the empty power supply slot is locked in the
counterclockwise position (see Figure 13 on page 15).
If necessary, pull the spring-loaded locking pin in the release lever away from
the chassis and turn the release lever counterclockwise until it stops. Let go of
the locking pin in the release lever. Ensure that the pin is seated inside the
corresponding hole in the chassis.
Using both hands, slide the power supply straight into the chassis until the power
supply is fully seated in the chassis slot. The power supply faceplate should be
flush with any adjacent power supply faceplates.
The small tab on the metal housing that is controlled by the release lever must
be inside of the corresponding slot at the bottom of the power supply (see Figure
20 on page 25). This tab is used to pull the power supply down in the chassis
slot, prior to removing the power supply.
While firmly pushing the handle on the power supply faceplate with one hand,
use your other hand to pull the spring-loaded locking pin in the release lever
away from the chassis and turn the release lever clockwise until it stops.
Let go of the locking pin in the release lever. Ensure that the pin is seated inside
the corresponding hole in the chassis.
Move the AC input switch in the chassis above the power supply to the on (
position and observe the status LEDs on the power supply faceplate. If the power
supply is correctly installed and functioning normally, the
light steadily, and the
PS FAIL
LED is not lit.
