Replacing Cooling System Components on the SRX1400 Services Gateway

When the airflow through the chassis is inhibited because of a clogged filter or a fan
failure, you must replace the respective component. The cooling system components
support online insertion and removal.
The following topics provide instructions on how to replace these components:

Replacing the Fan Tray on the SRX1400 Services Gateway

The SRX1400 Services Gateway has one fan tray located in the side of the chassis and
can be plugged in from the rear of the chassis. The fan tray contains two fans. The fan
tray supports online insertion and removal. It weighs about 4.2 lb (1.9 kg).
You can also use the fan tray LED to detect the condition when the fan speed has reduced
to a safer value, so that the fan tray can be removed from the device safely.
Table 37 on page 116 provides the LED indications of the fan tray LED.

NOTE: To prevent overheating, install the replacement fan tray immediately
after removing the existing fan tray. We recommend that you reinstall the
fan tray within 3 minutes; otherwise, the services gateway temperature
exceeds the maximum recommended room temperature, and the device
shuts down automatically in 4 minutes.
