Replacing Memory Modules in SteelHead 150, 250, and 550 Appliances
This section describes how to replace memory modules in a SteelHead 150, 250, and 550 appliance.
Before you begin, work with Riverbed Support at https://support.riverbed.com to determine the type of memory for the motherboard in your appliance and to determine the correct slot location for the memory. Memory modules and slot locations vary according to the motherboard in your appliance.
When replacing memory, you must use approved memory modules. Contact your Riverbed sales representative to obtain the correct memory modules.
Note: When you replace memory modules, 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. For details, see
Electrostatic Discharge Guidelines.
To replace the memory modules
1. Power down the system.
2. Disconnect the appliance from the electrical outlet and peripherals.
3. Remove the two locking screws on the back of the chassis.
