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. All installed power supplies must blow air in the same direction
and must match the airflow direction of the installed fan modules.
You need the following tools and materials to replace a 350 W or 715 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 a 350 W or 715 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 right 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.
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.
