Installing a DRAM DIMM

Follow these steps to install a DRAM DIMM:

Note You should start installing the DIMM memory from the innermost slot to the outermost slot.

Step 1 Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD

voltages to ground.

Step 2 Turn off power to the router.

Alternatively, the Cisco 3900 series routers support OIR. (See the “Online Insertion and Removal on a

Cisco ISR G2 Router” section on page 22)

Step 3 Locate the DIMM connector.

Note The DIMM connectors on the double-wide E-Series Servers are positioned at an angle and the DIMM

should be inserted at approximately the same angle.

Step 4 Make sure that both latches on the DIMM connector are in the open position.

Step 5 Orient the DIMM so that the polarization notch on the DIMM lines up with the notch on the connector.

See Figure 18.

Step 6

Insert the DIMM into the connector.

Step 7 Carefully and firmly press the DIMM into the connector until the latches close onto the DIMM. Make

sure that both latches snaps to the closed position against the DIMM. See Figure 19.
