Fan tray overview
Back-to-front airflow fan tray
Introduction to back-to-front airflow fan tray
The HP A5830AF-48G back (power side) to front (port side) airflow Fan
Tray (JC692A), referred to as back-to-front airflow fan tray hereafter, is a
fan tray with blowing fans that blow air to the inside of the device. It
comprises four separate fans. The back-to-front airflow fan tray features
small size, fast heat dissipation, and hot swapping, and can
automatically adjust the fan speed based on the device temperature.
Figure 1 shows the structure and air flow of the fan tray.
The fan tray provides a status LED to indicate the operating status of the
module. When the switch is running, the LED can have the following
statuses:
•The LED displays green—The fan tray operates properly.
•The LED displays red—The fan tray has a fault.
•The LED is off—The fan tray is not correctly installed or has a fault.

Installing and replacing a fan tray
You can install and replace the back-to-front airflow fan tray and
front-to-back airflow fan tray in the same way. For more information, see
“Installing a fan tray“ and “Replacing a fan tray.”
Installing a fan tray
IMPORTANT:
Before installing a fan tray, make sure that the airflow direction of
the module meets the ventilation requirement at the installation site.
Follow these steps to install a fan tray:
Step1 Wear an ESD-preventive wrist strap, and make sure that it
makes good skin contact and is properly grounded.
Step2 As shown in callout 1 of Figure 3, use a screwdriver to loosen
the captive screws on the blank filler panel of the fan tray slot,
and then remove the blank filler panel.
Step3 Unpack the fan tray.
Step4 As shown in callout 2 of Figure 3, holding the fan tray with both
hands with the upside (marked with an airflow direction label)
on top, gently push the fan tray into the slot along the guide
rails until the fan tray completely seats into the slot.
Step5 Use a Phillips screwdriver to fix the captive screws on the fan
tray to secure it into the switch chassis.
Step6 When the switch is running, check the status LED of the fan tray.
If the LED displays green, the installation is correct.
