The power supplies are hot swappable, which means you can remove and replace them without
powering down the system. You can remove and insert a power supply without opening the chassis.
If the device contains redundant 12-volt power supplies, you can remove one of the power supplies
without interrupting operation. The remaining power supply provides enough power for all the ports.
For more information about removing and installing the power supplies, refer to
DANGER
The power supplies are hot swappable, which means they can be removed and replaced while
the chassis is powered on and running. However, Brocade recommends that you disconnect the
power supply from the wall outlet before removing and replacing the supply. The device can be
running while a power supply is being installed or removed, but the power supply itself should not
be connected to a power source. Otherwise, you could be injured or the power supply or other
parts of the device could be damaged.
About replacement power supplies
Replacement power supplies for the SX-ACPWR-SYS and SX-ACPWR-POE are functionally equivalent
to the original power supplies, and can be used in combination with the original power supplies in
the same chassis. Although the model numbers for both the newer and older versions of the power
supplies are identical, the front of the power supplies are visually different and the manufacturing
part numbers are different.
The following illustration shows a side-by-side comparison of the SX-ACPWR-SYS replacement
power supply and the original power supply. The one on the left is the replacement power supply
and the one on the right is the original power supply.
