Cisco Cisco Email Security Appliance X1050

Remove the four 1GB DIMMs and replace them with the 2GB DIMMs, one at a time. Repeat the 
following procedure for each DIMM.

You must insert the new DIMMs into the same slots used be the old DIMMs. To ensure the same slots 
are used, replace the DIMMs one at a time.

 

 
If you do not insert the new DIMMs into correct slots, the appliance will not boot when the power is 
turned on.

Pull the latches away from the DIMM at both ends, as shown below. Note that the following figure 
shows a DIMM that may be different from the DIMM you will be installing.

Remove the 1GB DIMM and dispose of it.

When both ends of the DIMM are released from the socket, grasp the ends of the DIMM with your 
thumb and forefinger and pull the DIMM completely out of the socket.

Remove a new 2GB DIMM from the antistatic container.

To prevent ESD damage, handle the edges of the DIMM only; avoid touching the memory modules, pins, 
or traces (the metal fingers along the connector edge of the DIMM), along the connector edge, as shown 
below. Note that the DIMM shown below may be different from the DIMM you will be installing.

Hold the DIMM component side up, with the connector edge away from you. Line up the notch in 
the connector traces with the notch in the socket on the board.

The DIMM is designed in such a way that the connector will fit only one way.
