Before installing a 750 W DC power supply (part no. XN-DCPWR-750W-F or
XN-DCPWR-750W-R):
- Verify that the switch chassis
has been grounded (see Grounding the Switch Chassis).
- Verify that the airflow direction
for the power supply is the same as the airflow direction of the installed fan
modules in the switch.
To install the power supply, follow these steps:
Caution
The handle on the
power supply is not designed to be used to lift or carry the power supply or the
switch to which it is attached.
- Attach an
ESD-preventive wrist strap to your bare wrist and connect the metal end to an
appropriate ground point on the rack.
-
If necessary, remove a blank panel from the rear of the
switch.
-
Verify that the power supply is
right side up.
-
Carefully slide the power
supply all the way into the power supply bay.
- Push the power supply in
until the latch snaps into place.
Caution
Do not slam the power supply into the
switch.
-
To install a second power
supply, repeat the procedure.
When you are finished, connect the
ground wire to each power supply. See Connecting the Ground Wire to a 750 W DC Power Supply.
