Understanding and Maintaining Components 4 Remove the replacement PSU from the shipping container. Inspect the PSU for obvious damage. 5 Slide the new PSU into the open bay until it seats completely and the retaining latch resets. 6 Reconnect the power cord and replace the security bale. 7 Turn ON the PSU. The PSU's Power On LED lights up, its Fault LED goes out, and the Power Supply LED on the front bezel changes to solid green to indicate normal PSU status. Cooling Fan Module The cooling system consists of two high-performance (80-CFM) cooling fans enclosed in a single fan module (see Figure 5-12). The fan module fits into the open bay at the rear of the storage subsystem and is hot-swappable. Figure 5-12 Cooling Fan Module If the storage subsystem temperature exceeds the established threshold of 60° C (140° F), the fan status LED on the front bezel begins to flash amber. (The SAF-TE processor monitors the temperature and reports when this condition occurs.) 5-15

Understanding and Maintaining Components
4
Remove the replacement PSU from the shipping container.
Inspect the PSU for obvious damage.
5
Slide the new PSU into the open bay until it seats completely
and the retaining latch resets.
6
Reconnect the power cord and replace the security bale.
7
Turn
ON
the PSU.
The PSU’s Power On LED lights up, its Fault LED goes out, and
the Power Supply LED on the front bezel changes to solid green
to indicate normal PSU status.
Cooling Fan Module
The cooling system consists of two high-performance (80-CFM)
cooling fans enclosed in a single fan module (see
Figure 5-12
). The
fan module fits into the open bay at the rear of the storage
subsystem and is hot-swappable.
Figure 5-12
Cooling Fan Module
If the storage subsystem temperature exceeds the established
threshold of 60° C (140° F), the fan status LED on the front bezel
begins to flash amber. (The SAF-TE processor monitors the
temperature and reports when this condition occurs.)
