Replacing Fan Modules
You can replace internal power supplies and fan modules, as needed, while the switch is operating ("hot
swapping").
For each switch, ensure that all installed power supplies and fan modules have the same the airflow
direction: either front-to-back or back-to-front.
Follow the procedures in this section to remove and replace power supplies and fan modules, and to

Replacing an 1100 W AC Power Supply
The 1100 W AC power supplies with part number 10941 are compatible with the VSP 4900 switch.
The switch has 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 a 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 a 1100 W AC power supply, follow these steps:
1 Disconnect the AC power cord from the wall outlet and from the power supply.
2 Note the orientation of the installed power supply, and the location of the latching tab at the right of
the unit.
