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.
