Replacing the 8/40 SAN Switch power supply and fan assembly
CAUTION:
Disassembling any part of the power supply and fan assembly voids the warranty
and regulatory certifications. There are no user-serviceable parts inside the power supply and
fan assembly. Because the cooling system relies on pressurized air, do not leave any of the fan
assembly slots empty longer than two minutes while the switch is operating. If a fan assembly
fails, leave it in the switch until it can be replaced. Maintain all fan assemblies in operational
condition to provide redundancy.
Replacing the power supply and fan assembly unit takes approximately two minutes. You will
need:
•
New power supply and fan assembly FRU (one unit)
•
Phillips-head screwdriver #1
To replace the power supply and fan assembly unit:
1.
Use a Phillips-head screwdriver to unscrew the captive screw on the power supply fan
assembly you are replacing.
2.
Remove the power supply fan assembly you are replacing from the chassis by pulling the
handle out and away from the chassis.
3.
Install the new power supply fan assembly unit in the chassis:
a.
Orient the new fan assembly with the captive screw on the right.
b.
Gently push the power supply fan assembly into the chassis until it is firmly seated.
CAUTION:
Do not force the installation. If the power supply fan assembly does not
slide in easily, ensure that it is correctly oriented before continuing.
c.
Secure the fan assembly to the chassis by screwing in the captive screw.
4.
Verify that the fan status LED is lit steady green to indicate normal operation.
5.
(Optional) Display the fan status using the
fanshow
command from the CLI.
