NOTE: Each AC power supply must be connected to a dedicated AC power
source outlet.
To install an AC power supply in a J-EX8200 switch (see Figure 54 on page 116):
1.
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
2.
If the power supply slot has a cover panel on it, unscrew the screw on the side of the
cover panel in the counterclockwise direction using the Phillips (+) screwdriver, number
1, and remove the cover panel. Save the cover panel for later use.
3.
Taking care not to touch power supply components, pins, leads, or solder connections,
remove the power supply from its bag.
4.
Flip the
Enable
switch next to the appliance inlet on the power supply to the Standby
position.
5.
Unscrew the captive screw in the counterclockwise direction using the Phillips (+)
screwdriver, number 1.
6.
Pull the captive screw away from the faceplate of the power supply to release the
latch.
7.
Pull the handle away from the faceplate of the power supply until it is perpendicular
to the faceplate.
NOTE: Power supplies can be installed in any slot. You do not have to
install the power supplies in serial order.
8.
Using both hands, place the power supply in the power supply slot on the front of the
switch. Slide the power supply straight into the chassis until the power supply is fully
seated in the slot. Ensure the power supply faceplate is flush with any adjacent power
supply faceplates or power supply cover panels.
9.
Push the handle towards the faceplate of the power supply until it is flush against the
faceplate.
10.
Push the captive screw into the power supply faceplate. Ensure that the screw is
seated inside the corresponding hole on the faceplate.
11.
Tighten the captive screw by turning it clockwise using the Phillips (+) screwdriver,
number 1. When the screw is completely tight, the latch locks into the switch chassis.
