not used, make sure the rubber gaskets are in the QSFP transceivers.

Power supply removal and replacement
Use this procedure to remove and replace a power supply.
The Brocade DCX 8510-4 can continue operating during the replacement if the second 220 VAC
power supply is operating. If the Brocade DCX 8510-4 is supplied with 110 VAC (nominal), there is a
risk of some blades being powered off for lack of power during the replacement.
This is why Brocade always recommends using 220 VAC (nominal).
Brocade DCX 8510-4 power supplies are 100-240 VAC, auto-sensing.
Time and items required
The replacement procedure for each power supply takes less than five minutes. A power supply
unit or filler panel is required for the power supply replacement.
