The 1100 W AC power supply with part number XN-ACPWR-1100W-FB is compatible with all 5720
Series models.
These switches have two bays for hot-swappable power supplies. In a switch with a
redundant power configuration, you can replace one AC power supply without powering down
the switch.
You need the following tools and materials to replace an 1100 W AC power supply:
Thermal protective gloves
AC power cord, if you will not be
re-using the cord from the removed power supply
To replace an 1100 W AC power supply, follow these steps:
Disconnect the AC power cord from the wall outlet and from the power supply.
Note the orientation of the installed
power supply, and the location of the latching tab at the left of the unit.
Push the latching tab toward the
power supply handle and pull outward on the handle to disengage the power supply
internal connectors. See Removing an 1100 W AC Power Supply.
Carefully slide the power supply the rest of the way out of the switch.
Caution
Power supplies can
become very hot during operation. Wear thermal protective gloves when you remove
a power supply from an operating switch.
Note
If you are not
installing a replacement power supply, install a cover over the unoccupied power
supply bay. Unoccupied bays must always be covered to maintain proper system
ventilation and EMI levels.
Verify that the replacement power supply is oriented the same way as the unit you
removed, and has the same airflow direction.
