HP B-series 16Gb FC Switches Hardware Reference Guide

a. Verify that the airflow direction is the same as that of the fan you are replacing.
b. Orient the new fan with the captive screw on the right, as shown in Figure 34 (page 58).
CAUTION:
• Do not force the power supply into the chassis. If the fan does not slide in easily,
ensure that it is oriented correctly before continuing.
• After replacing a fan, if the switch powers down after 2 minutes, it is probably
because the new fan has a mismatched airflow.
c. Gently push the fan into the chassis until it is firmly seated.
d. Using the Phillips screwdriver, secure the fan to the chassis by tightening the captive
screw.

4. Verify that the fan status LED is steady green to indicate normal operation. See Table 8 (page
48) for more information.
Optionally, using the CLI, enter the fanShow command or chassisShow command to
display the power supply status.
You can also use Web Tools to view the fan status.
Replacing the HP SN6000B or SN3000B 16Gb FC Switch power supply and fan
assembly
The fans are fixed inside the combined power supply and fan FRU to provide the airflow needed
to cool the switch. Each FRU contains two fans. The system software measures and sets fan speed
through the tachometer interface.
The SN3000B switch comes with one power supply and fan assembly. Fabric OS identifies the
assemblies from right to left on the nonport side. Even though they are contained within a single
unit, the power supply and fan components are identified separately. In the chassisShow
command they are identified as Power Supply Unit:1 and Fan Unit:1.
The SN6000B switch has two power supply and fan assemblies. The two power supply and fan
assemblies are hot-swappable if replaced one at a time. They are identical and fit into either slot.
