CH A P T E R 5 WS - X6582 - 2PA DIMM Replacement Procedure This chapter describes the step-by-step procedure for the DIMM replacement for WS - X6582 - PA units. Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Caution Only memory approved by Cisco is supported. Do not attempt to install other devices or DIMMs, which are not approved by Cisco, in the DIMM sockets. Caution DIMMs are ESD-sensitive components and can be damaged due to mishandling. Ensure that they are handled with care during installation and removal. Step-by-Step Procedure To remove a DIMM and install a new DIMM for Cisco 7600 Series WS - X658 - 2PA units, follow these steps: Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide OL-5052-15 5-1 Chapter 5 Step 1 WS - X6582 - 2PA DIMM Replacement Procedure Look minutely at the top view of the WS - X658 - 2PA unit to identify the Baseboard/ Motherboard and the SPA Jacket Cover. See Figure 5-1. Figure 5-1 Locating the Motherboard and SPA Jacket Cover Label Component 1 Motherboard 2 SPA Jacket Cover Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide 5-2 OL-5052-15 Chapter 5 WS - X6582 - 2PA DIMM Replacement Procedure Step 2 Identify the DIMM slots as represented by labels 1 and 2. See Figure 5-2. Figure 5-2 Step 3 Locating DIMM Slots Label Component 1 DIMM 1 2 DIMM 2 Try to locate the side notches on both the sides of the DIMM slot. These are the locks of that hold the DIMM in place. Push these forward in the directions to release the DIMM modules as shown by the arrows. See Figure 5-3. Figure 5-3 Pushing the Locks Cisco 7600 Series Router SIP, SSC, and SPA Hardware Installation Guide OL-5052-15 5-3 Chapter 5 Step 4 After unlocking the DIMM, remove the DIMM from the slots. See Figure 5-4. Figure 5-4 Caution WS - X6582 - 2PA DIMM Replacement Procedure Removing DIMM from DIMM Slot Handle the DIMM only along the edges. Do not touch the memory modules, pins, or traces (metal fingers along the connector edge), to avoid damage. Step 5 Pull the retaining clips holding the DIMM away with your thumb. See A in Figure 5-5. Step 6 When both ends of the DIMM are released from the socket, grasp the ends of the DIMM with your thumb and forefinger, and pull it completely out of the socket. See Figure 5-4 and A in Figure 5-5. Then, in compliance with electronic waste laws, dispose the DIMM. Step 7 Install the replacement DIMM by holding the component-side facing up, with the connector edge (the metal fingers) away from you. Keep the sides of the DIMM between your thumb and index finger. See Figure 5-7 and B in Figure 5-5.

Do not use excessive force or touch the surface components, to avoid damage. Step 8 Tilt the DIMM at a 30 degree angle to the socket, and then insert the connector edge of the DIMM into the socket. Verify that the notches on the DIMM are properly aligned with the ones on the connector before fully inserting the DIMM. Step 9 Press down on the DIMM until the retaining clips lock the DIMM in place. See Figure 5-8. Step 10 Check the two alignment notches, and ensure that the clips are visible. If necessary, remove and reset the DIMM. See B in Figure 5-5.
