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 Riverbed Support at https://support.riverbed.com.

Replacing the disk drives
This section describes how to replace the hard disk drives (HDDs) and Solid State Drives (SSDs) in the 1U and 2U xx80 appliances. It includes these sections:
Before you begin
• When replacing a drive, replace only one drive at a time. You must use approved disk drives. To order disk drives, contact Riverbed Support at https://support.riverbed.com.
• If you need to replace an appliance, you can’t move the disks to preserve your data. Each disk is encoded with machine-level information and moving disks isn’t supported.
• When you replace disk drives, 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.
Always install the hard disk drive to the chassis after the chassis has been secured on the rack.
Replacing HDDs in 1U and 2U appliances
The 1U and 2U appliances are equipped with replaceable, hot-swappable disk drives. Replacement HDD 3.5-inch and SSD 2.5-inch drives are shipped in their carrier cases.
The 2U SteelCentral NetProfiler (2280, 4280-EX, and 4280-AN), SteelCentral 4180, 6180, and 8180 appliances and SteelCentral storage units are equipped with replaceable, hot-swappable 3.5-inch HDDs.
When replacing a drive, replace only one drive at a time. You must use approved disk drives. To order disk drives, contact Riverbed Support at https://support.riverbed.com.
When you replace disk drives, 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.
Use caution when you remove or replace components; they can become hot to the touch.
To replace the HDDs in the 1U and 2U appliance
1. Remove the bezel.
2. Identify the faulty disk drive. The disk drive LED is red for failed drives.

3. Press the orange locking-lever latch and pull the locking lever open.
Removing the disk drive
The disk drives for the 2U appliance are illustrated in
Figure: Removing the disk drive. The disk drives for the 1U appliance have the same orange locking-lever latch.
4. Slide the faulty disk drive tray out.
5. Slide in the new disk drive until it mates 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.
For SteelHead appliances, 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 SteelCentral appliances, see the user guide for the product if additional steps are necessary to run a self-test.
For SteelHead appliances, it takes approximately 3 to 4 hours, depending on the system load, to rebuild a new disk drive. You can configure SteelHead appliances to send an email to the administrator user when the disk drive has finished rebuilding.
Replacing the rear SSDs in 2U appliance
The SteelCentral 2U appliance includes two hot-swappable 2.5-inch SSDs on the rear of the appliance.
