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.
About required tools
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.

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 through a self-test automatically. The disk drive automatically begins proper operation with the other disk drives. You don’t need to set up or configure the new disk drive. For SteelHead appliances, it takes approximately 3 to 4 hours, depending on the system load, to rebuild a new disk drive. In the web interface you can configure SteelHead appliances to send an email to the administrator user when the disk drive has finished rebuilding.
