Replacing 2U Appliance Components

This chapter describes how to replace hard disk drives (HDDs), solid-state drives (SSDs), memory modules, fans, and power supply units in 2U appliances. Use caution when you remove or replace components; they can become hot to the touch.

• You must use approved components for the appliance to function properly. Installation of unapproved components will result in boot failure. To order components, contact Support at https://support.riverbed.com.

• Use the Riverbed magnetic reversible screwdriver (that is, Phillips-head and flathead) enclosed with your shipment to remove screws in the appliance. The magnetic screwdriver ensures screws aren’t lost in the appliance.

• When you replace appliance components, you must wear a grounded ESD antistatic strap to protect the hardware against electrostatic discharge. Make sure that the strap makes skin contact prior to handling equipment.

This section describes how to replace HDDs, power supplies, memory modules, and fans in the 2U appliances.

1. Power down the appliance and unplug all peripheral devices and the power cable.

2. Remove the screws on both sides of the chassis (see Figure: Removing the chassis cover on the 2U xx80 and 9800 appliance).

3. Place your thumbs on the recessed tabs (see Figure: Removing the chassis cover on 2U xx90 appliances, letter A) and slide the cover straight back and up (see Figure: Removing the chassis cover on 2U xx90 appliances, letters B and C).

1. Power down the appliance and unplug all peripheral devices and the power cable.

2. Facing the back of the appliance, remove the screw on the top of the appliance and loosen the two captive screws (see Figure: Removing the chassis cover on the 2U xx80 and 9800 appliance, letter A) on the back of the appliance.

3. Place your thumbs on the recessed tabs (see Figure: Removing the chassis cover on the 2U xx80 and 9800 appliance, letter B) and slide the cover straight back and up.

2. Loosen the retaining screws on the top of the riser bracket.

– For 2U xx90 appliances, loosen the two captive screws on the top of the riser bracket, see Figure: Loosening the riser brackets retaining screws in the 2U xx90 appliance.

– For 2U xx80 appliances, loosen the four captive screws on the riser bracket, two located on the top and two located at the back, see Figure: Loosening the riser bracket retaining screws in the 2U xx80 appliance.

3. Lift straight up to remove the riser brackets from the chassis.

4. If you have an air duct, release the air duct from the guide pins and then remove it from the chassis.

2. Identify the faulty disk drive. The disk drive LED is red for failed drives.

3. Press the locking-lever latch and pull the locking lever open.

4. Slide the faulty disk drive tray out.

5. Slide in the new disk drive until it engages with the back connectors in the chassis.

6. Push to secure the locking lever until it clicks into place. The disk drive LED lights green when connected.

The new disk drive runs a self-test automatically and then starts working with the other drives without any setup or configuration needed. For SteelHead appliances, rebuilding the new drive takes about 3 to 4 hours, depending on system load. You can set up the web interface to send an email notification to the administrator once the rebuild is complete.

Some 2U appliances include two hot-swappable 2.5-inch SSDs on the rear of the appliance.

2. Press the locking-lever latch and pull the locking lever open.

3. Insert the drive into the chassis.

4. Press the locking lever to secure the drive.

2. Press the latch (Figure: Pressing the power supply unit latch and removing the power supply from the 2U xx90 appliance, letter A), and pull the power supply unit toward you (Figure: Pressing the power supply unit latch and removing the power supply from the 2U xx90 appliance, letter B).

3. Slide the power supply unit out of the chassis. Put the defective power supply unit aside; wait until it cools down before touching it.

4. Press and hold the latch and push the power supply into the chassis using the handle.

5. Plug the AC power cord into the new power supply unit.

2. Remove the chassis cover. For details, see Removing the chassis cover on 2U xx80 appliances.

3. Remove the riser brackets and air duct. For details, see Removing the riser brackets and air duct in 2U appliances.

4. When adding new memory, add the memory in the blue slots first. Once the blue slots are full, populate the black slots. Use the lowest lettered/numbered slots first. When replacing memory, be sure to place the new memory module in the slot from which you removed the faulty memory module. See Figure: Memory module slot locations in the 2U appliance for memory module locations.

5. Press the clips outward to unlock them and gently pull the memory module out of the slot.

6. Align the memory-module edge connector and insert it into the slot. When inserted properly, the memory slot locking levers lock automatically onto the indentations at the ends of the module.

7. Press the clips inward to lock the module in place.

8. Ensure that all clips are in the upright locked position.

9. Replace the riser brackets and air duct. For details, see Removing the riser brackets and air duct in 2U appliances.

10. Replace the chassis cover.

11. Replace the power cords and peripherals.

12. Power on the appliance.

2. Remove the chassis cover.

3. Identify the faulty fan.

4. If necessary, disconnect the fan power cable from the backplane.

5. Press the release tab (see Figure: Removing a fan in the 2U xx90 appliance, letter A) and pull the fan straight up to remove it (see Figure: Removing a fan in the 2U xx90 appliance, letter B).
