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.

Introduction to front-to-back airflow fan tray
The HP A5830AF-48G front (port side) to back (power side) airflow Fan
Tray (JC693A), referred to as front-to-back airflow fan tray hereafter, is
a fan tray with drawing fans that draw air from the inside of the device.
It comprises four separate fans. The front-to-back airflow fan tray
features small size, fast heat dissipation, and hot swapping, and can
automatically adjust the fan speed based on the device temperature.

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.

NOTE:
•If you insert the fan tray with the upside facing downward, you
cannot completely insert the module into the slot. If this happens,
pull the fan tray out and then insert it again with the upside on
top.
•If you cannot fix the captive screws, check whether the fan tray is
correctly installed.
Replacing a fan tray
CAUTION:
•When replacing a fan tray from a running switch, be cautious of
electricity hazards, and do not touch the rotating fans to avoid
bodily injury.
•After you unplug a fan tray from a running switch, install a new
fan tray within eight minutes to ensure proper ventilation and heat
dissipation of the switch.
When the fan tray is faulty, you must replace it.
Follow these steps to replace a fan tray:
Step1 Prepare an antistatic bag for the removed fan tray.
Step2 Wear an ESD-preventive wrist strap, and make sure that it
makes good skin contact and is properly grounded.
Step3 As shown in callout 1 of Figure 4, use a screwdriver to loosen
the captive screws of the fan tray.

9
Step4 As shown in callout 2 of Figure 4,holding the handle of the fan
tray, pull the module out of the chassis.
Step5 Put the removed fan tray into the antistatic bag.
Step6 Install a new fan tray. For more information, see “Installing a
fan tray.”
Figure 4 Remove a fan tray
(1) Loosen the captive screws of the fan tray
(2) Pull the fan tray out of the chassis

10
NOTE:
If you replace a fan tray from a running switch, and the airflow
direction of the new fan tray is different from the former one, the
alarm message System fan airflow direction is not preferred on
slot X, please check it. appears. To eliminate the alarm, replace
another fan tray with the same airflow direction, or use the fan
prefer-direction slot
slot-number { power-to-port | port-to-power }
command in system view to change the preferred airflow direction
of the switch.
