6. Verify that the LEDs on the new power supply display steady green while the Brocade 6520 is
operating (refer to Table 8 ). If the LEDs are not steady green, ensure that the power supply is
securely installed and seated properly.
Optionally, if using the command line interface (CLI), enter the psShow command at the
command line prompt to display the status. You can also use the chassisShow command. The
power supply status can also be viewed using the Web Tools application.
Fan removal and replacement
The Brocade 6520 has three fans as displayed in Figure 2 . The Fabric OS identifies the fan
locations from left to right as fan #3, fan #2, and fan #1.
CAUTION
Disassembling any part of the fan voids the part warranty and regulatory certifications. There are
no user-serviceable parts inside the fan. Because the cooling system relies on pressurized air, do
not leave any of the fan slots empty longer than two minutes while the switch is operating. If a fan
fails, leave it in the switch until it can be replaced.
Maintain all three fans in operational condition to provide redundancy.
