Installing and removing a power supply

The switch provides two power supply slots. It comes with power supply slot PWR1 empty and power
supply slot PWR2 installed with a filler panel. You can install one or two power supplies for the switch
as required. For the power supplies available for the switch and their specifications, see S6520X-EI
& S6520X-HI Switch Series Hardware Information and Specifications.
WARNING!
• To avoid bodily injury or switch damage, strictly follow the procedures in
Figure2-28
• You must provide a circuit breaker for each power supply.

CAUTION:
• To prevent damage to the power supply and the connectors on the backplane, insert the power
supply gently. If you encounter a hard resistance when inserting the power supply, pull out the
power supply and insert it again. Make sure the power supply has a good contact with the
connectors.
• When the switch has two power supplies working in 1+1 redundancy, removing one power supply
does not affect system operation. If the switch has only one power supply, removing the power
supply causes power down of the switch.
• If you are not to install a new power supply after removing the old one, install a filler panel in the
slot in time.
• Use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws on a power supply.
