Extreme Networks Consolidated ExtremeXOS Hardware Installation Guide

Pre-Installation Requirements
You need the following tools and equipment to install or remove the power supply controller:
● ESD-preventive wrist strap
● # 2 Phillips screwdriver
● Power supply controller
● BlackDiamond 10808 switch
Removing a Power Supply Controller
The power supply controllers are hot-swappable. You do not need to turn off power to a BlackDiamond 10808 switch
to remove and replace a power supply controller.
If you are replacing both power supply controllers, remove and replace the controllers one at a time. After the first
controller is removed and replaced, wait for the Status LED to light solid green, indicating normal operation, before
you replace the second controller. DO NOT remove both power controllers simultaneously; doing so will cause the
entire system to power down.
To replace a power supply controller:
1 Attach the ESD-preventive wrist strap to your wrist and connect the metal end of the strap to the
ground receptacle on the top left corner of the BlackDiamond chassis front panel.
2 If a blank faceplate is covering the power supply controller bay, remove it and save it for future use.
3 Using a #2 Phillips screwdriver, loosen the captive retaining screws on the power supply controller.
4 Remove the power supply controller from the slot.
