Replacing 1U Appliance Components

This chapter describes how to replace hard disk drives (HDDs), solid-state drives (SSDs), memory modules, fans, and power supply units in 1U appliances.

Use caution when you remove or replace components; they can become hot to the touch.

You need the following tools and equipment to replace appliance components:

• 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 components such as the chassis cover and power supplies in 1U xx90 appliances.

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

2. Remove the two screws located at the back of the chassis (see Figure: Removing the 1U xx90 chassis cover rear screws), and the three screws located on the top of the appliance, (see Figure: Removing the screws and chassis cover on the 1U xx90 appliance). Slide the cover back 1 cm and lift the cover straight up and away from the appliance.

If the Intelligent Platform Management Interface (IPMI) alarm triggers when you open the chassis cover, enter the clear hardware error-log command in the CLI to clear the alarm. For details, see the Riverbed Command-Line Interface Reference Manual.

3. To replace the cover, gently rotate it to align and secure the two pins on the left and right sides of the chassis enclosure (see Figure: Replacing the chassis cover on 1U xx90 appliances), then slide it into place.

The 1U xx90 appliances have replaceable, hot-swappable power supply units. Facing the front of the appliance, PSU1 is on the left and PSU2 is on the right.

2. Press in the release tab (see Figure: Removing the power supply unit from the 1U xx90 appliances, letter A), and pull the power supply unit toward you (see Figure: Removing the power supply unit from the 1U xx90 appliances, letter B), sliding the unit out of the chassis. Put the defective power supply unit aside; wait until it cools down before touching it.

3. On the new power supply unit, pushing the unit into the chassis until it clicks.

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

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

2. Facing the back of the appliance, remove the 14 screws from the appliance: four on the front and back, and three on the right and left side.

3. Lift the cover straight up to remove the chassis cover from the appliance. For details, see Figure: Removing the cover on the 3080 appliance.

1. Power down the appliance and remove the chassis cover. For details, see Removing the chassis cover on 3080 appliances.

2. The 3080 appliance has two internal SSD cards inside the appliance. Remove the locking screw of the SSD you want to replace.

3. Holding each side of the SSD, carefully pull the SSD from the pin connector.

4. Insert the new SSD into the pin connector.

5. Press the SSD down and insert the locking screw.

6. Replace the chassis cover.

The 3080 appliance has two replaceable, hot-swappable management drives located at the back of the appliance. When replacing a drive, replace only one drive at a time. These drives can be all HDD, all SSD, or a mixed configuration of both with the following restrictions:

• If the system is populated with both management drives as SSD, a failed SSD can be replaced with either an SSD or HDD.

• If the system is populated with both management drives as HDD, a failed HDD must be replaced with an HDD only.

• Support for SSD management drives requires a minimum of the following RiOS software versions:

1. To unlock a drive, use a screwdriver to turn the screw head on the drive 90 degrees to the left.

2. Press the lock-lever button. The drive snaps open.

3. Slide the faulty disk drive tray out.

4. Replacement drives are shipped in their carrier cases. Slide in the new disk drive until it engages with the back connectors in the chassis.

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

6. To lock the drive, turn the screw head on the drive 90 degrees to the right.

For SteelHead appliances, the new disk drive automatically performs a self-test and begins working with the other drives without any setup or configuration. Rebuilding the drive can take 3 to 4 hours, depending on system load. You can configure the web interface to send an email notification to the administrator once the rebuild is complete.

Always use Riverbed-approved memory modules. Replacing the existing memory module with a module of a different size causes the appliance to fail.

1. Power down the appliance and remove the chassis cover. For details, see Removing the chassis cover on 3080 appliances.

2. The 3080 appliance has two dual in-line memory module (DIMM) slots: slot 0 and slot 1. When replacing memory on the appliance, place the new memory module in the slot from which the faulty memory module was removed.

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

4. 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.

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

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

7. Replace the chassis cover.

8. Reattach the power cords and peripherals.
