Installing an AC power module
IMPORTANT:
Make sure that the number of power modules is sufficient for the switch to operate properly.
•
Each receptacle on the PEM corresponds to a power module slot. To enable an AC power module to
•
work, provide power module to the relevant receptacle.
Distribute power modules in the upper and lower frames evenly on the S12518.
•
The procedures for installing an AC power module are similar to installing a DC power module. For
•
more information, see

Installing a fan tray

CAUTION:
The fan trays are heavy. Do not try to move a fan tray by yourself.
•
Hold a fan tray by the bottom when moving it. Never attempt to lift a fan tray with its handle because the
•
handle is not designed to support weight. Doing so might result in bodily injury or damage to the
module.
