CHAPTER 6: POWER SUPPLIES
6.3 AC POWER SUPPLY REPLACEMENT
CAUTION: Disconnect the power cord before removing the power supplies. Also, disconnect all power cords before servicing.
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the switch
chassis.
NOTE: If a PSU fails, you must replace the entire unit. There are no field serviceable components in the PSU. To request a hardware
replacement, contact Black Box Technical Support at 877-877-2269 or [email protected]
1. Disconnect the power cable from the PSU.
2. Use the grab handle to slide the PSU out of the power supply bay.
3. Use the grab handle on the replacement PSU to slide it into the power supply bay.
