REPLACE THE POWER SUPPLY UNIT
Notes:
• Before replacing the PSU, it's necessary to ensure that the other power
supply unit on the switch is in a power supply state during the replace-
ment, otherwise unplugging the PSU will cause the switch to power off
resulting in a business interruption.
• The 2 power slots on the switch are 1+1 backup. When only one unit is
working, it can ensure that the switch works normally. If multiple units
need to be replaced, replace them one by one. During each replacement
process, it's necessary to ensure that the other unit is functioning properly
(the LED light is green).
Step 1: If the switch functions with a single unit only, disconnect the power
cord from the unit and let the switch power down; otherwise, do a hot swap
directly.
Step 2: Grasp the handle and use your thumb to move the release latch
toward the handle side while pulling out the PSU outward. Use the other
hand to drag the bottom of the PSU and slowly pull it all out of the switch.
Step 3: Install the backup unit into the slot, refer to the installation guide
"Install an Additional Power Supply Unit"; if there is no need to install a new
PSU, install the dummy panel to prevent dust from entering.
Subsequent processing: If the replaced unit does not operate properly, con-
tact the equipment dealer or maintenance personnel for technical support.
