Cisco Systems 7401ASR manual Replacing the Sdram Dimm

Chapter 1 Overview and Parts Installation

Replacing the SDRAM DIMM

Step 2 Using a Phillips screwdriver, loosen the screw of the port adapter latch, and rotate the port adapter latch until it clears the faceplate of the port adapter. The latch can rotate 360o.

Step 3 Pull the port adapter about halfway out of the port adapter slot. (If you remove a port adapter filler plate, keep the blank port adapter for use in the router if you should ever remove the port adapter. The port adapter slot must always be filled.)

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter. After disconnecting the cables, pull the port adapter from the chassis slot.

Step 5 Locate the port adapter slot guides inside the Cisco 7401ASR router. They are near the top, and are recessed about one-half inch.

Caution The port adapter must slide into the slot guides under the chassis lid. Do not allow the port adapter components to come in contact with the system board or the port adapter could be damaged.

Note If it is easier to attach the port adapter cables with the port adapter inserted halfway, attach the cables before seating the port adapter and securing the port adapter latch.

Step 6 Locate the port adapter slot guides. Carefully slide the port adapter into the port adapter slot and seat it. When installed, the port adapter input/output panel should be flush with the face of the router.

Step 7 Rotate the port adapter latch to the upright locked position and use a Phillips screwdriver to tighten the latch screw. Loosen the latch screw, if needed, to be able to rotate the latch over the port adapter. Then tighten the latch screw.

This completes the port adapter installation procedure.

Caution To ensure the proper flow of cooling air across the internal components, make sure a port adapter filler panel is installed in the unoccupied port adapter slot.

For further installation procedures, see Chapter 2, “Rack-Mounting, Tabletop Installation, and Cabling.”
