The IP application switch platform contains several field replaceable units (FRUs). The FRUs provide the ability to replace parts of the system without replacing the complete system. The FRUs currently available for this platform are:
The 8400/8800 platforms have a removable fan tray and filter. You can change or replace the fan tray and filter as part of the routine maintenance of the unit, or in the event of a fan failure. The air filter in the BIG-IP unit is designed to remove airborne contaminants and requires replacement during the life of the product. The fans in the fan tray run constantly while the unit is on. Over time, the fans will wear out, requiring you to replace the fan tray.
Note: We recommend that you inspect the fan tray and filter every four months. Replace the fan tray if any of the fans are not functional. Replace the filter when you replace the fan tray.
You do not need special tools to replace the fan tray and filter. You can perform this maintenance while the unit is running.
However, we recommend that you perform the fan tray and filter replacement only on the standby unit in a redundant system while the unit is powered down. After you install the fan tray and filter in the standby system, power up the unit, then force the active system to fail over and install the fan tray and filter replacement in the other unit of the redundant system.

The fan tray is held on the chassis by a knurled fastener. Loosen the knurled fastener by turning it counter-clockwise.
4.
Slide the new fan tray and filter into the fan tray and filter slot.
The tray is automatically turned on when you slide the tray completely into the chassis.
Figure 5.1 shows an example of the fan and filter tray assembly partially removed from the BIG-IP system. You can also replace the filter without replacing the fan tray. This requires you to remove the fan tray, and take out the old filter, and insert a new one.

5.
Push the fan tray and filter back into the system.
The tray is automatically turned on when you slide the tray completely into the chassis.
The 8400/8800 series platforms have removable power supplies. You can change or replace the power supply in the event of a power supply failure.
You do not need special tools to replace the power supply. We recommend that you perform the power supply replacement on the standby unit in a redundant system after halting it and powering the system off. After you install the power supply in the standby system, force the active system to fail over and install the power supply replacement in the other unit of the redundant system.
1.
On the LCD panel, press the X button, then use the arrow keys to navigate to the System menu.
7.
Hold the X button for 4 seconds to power down the unit.
2.
The power supply is held on the chassis by two knurled fasteners. Loosen the knurled fastener by turning it counter-clockwise.
4.
Slide the new power supply into the power supply slot.
The power supply is connected to the system when you slide it completely into the chassis.

The 8400/8800 series platforms have a removable drive tray. You can change or replace the drive tray as part of the routine maintenance of the unit, or in the event of a drive failure.
We recommend that you back up your BIG-IP configuration files any time you change them. In the event of a drive failure, you can replace the hard drive tray, then you can reinstall the version of the BIG-IP software you were running and use the configuration backup to restore the system to its previous state.
You do not need special tools to replace the drive tray. We recommend that you perform the drive tray replacement only on the standby unit in a redundant system. After you install the drive tray in the standby system, power up the system and force the active system to fail over. Install the drive tray replacement in the other unit of the redundant system. You must halt the system and shut it down before you replace the drive tray.
1.
On the LCD panel, press the X button, then use the arrow keys to navigate to the System menu.
7.
Hold the X button for 4 seconds to power down the unit. After you halt and power off the system, you can replace the drive tray.
2.
The drive tray is held on the chassis by two knurled fasteners. Loosen the knurled fastener by turning it counter-clockwise.
4.
Slide the new drive tray into the drive tray slot.
The tray is automatically turned on when you slide the tray completely into the chassis.
