Installing 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 install a power supply controller.
To install a power supply controller:
1 Attach the ESD-preventive wrist strap to your wrist and connect the metal end 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 Verify that the power supply controller is right side up.
4 Slide the power supply controller into the slot, aligning the notch on the top of the slot with the
power supply controller.
5 Tighten the captive thumbscrews to secure the power supply controller into the slot.
Verifying a Successful Installation
After you supply power to the switch, the switch performs a power-on self test (POST).
During the power-on self test:
● All ports are temporarily disabled.
● The packet LED is off.
● The power LED is on.
● The MGMT LED flashes until the switch successfully passes the POST.
If the switch passes the POST, the MGMT LED blinks at a slow rate (one blink per second). If the switch
fails the POST, the MGMT LED shows a solid yellow light.
