For switches with replaceable power supplies, refer to the following information to replace the power supplies. SLX 9740-40C switches have two power supply slots. SLX 9740-80C switches have four power supply slots. In a switch with a redundant power configuration, you can replace one power supply without powering down the switch ("hot swapping"). Power supply slots are located on the rear panel of the switch.
Images in this topic might show switches that are not identical to the ones you are using. However, the procedure for replacing a power supply is the same for all Extreme Networks switches.
Note
Read all of the information in this chapter thoroughly before attempting to replace a power supply.
