Before installing a 750 W DC power supply (part no. XN-DCPWR-750W-F or
XN-DCPWR-750W-R):
- 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 (label on the bottom).
-
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."
