Replacing Disk Drives
The following sections describe how to replace disk drives in the xx50 appliances.
Note: When you replace the disk drive, 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.
If you have older hardware (for example, xx20 appliances), see the documentation set for RiOS v6.5.x or earlier. To service appliance 50, 100, 200, and 300 disk drives, contact Riverbed Support at
