6. Verify that the LEDs on the new power supply are steady green when the switch is operating.
See Table 8 (page 48) for more information. If the LEDs are not steady green, ensure that the
power supply is installed securely.
Optionally, using the CLI, enter the psShow command or chassisShow command to display
the power supply status.
You can also use Web Tools to view the power supply status.
Replacing an HP StoreFabric SN6500B 16Gb FC Switch fan
The HP StoreFabric SN6500B 16Gb FC Switch has three fans, as shown in Figure 2 (page 9).
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 assembly 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 for 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 ensure redundancy.
See Table 8 (page 48) for the power supply status LED colors, patterns, and recommended actions,
if any.
