6.4.2 Installing the RPU2

Step 1: Power off the switch or power switches if two PSUs are installed.

Step 2: Align the edges of the RPU2 with the guides in the RPU2 slot and push the card inside the router. Pull the ejector levers at both side of the RPU2 inward until they form the smallest degree with respect to the RPU2 panel.

Step 3: Fasten the captive screws on the RPU2.

Step 3: Power on the router and check that the RPU2 LED is blinking.

6.5 Replacing the SDRAM

This section describes how to replace an SDRAM (Synchronous Dynamic Random Access Memory) module. SDRAM modules can be replaced on the RPU only. Memory on the RPU2 cannot be replaced. The following flowchart provides an overview of the SDRAM replacement process.
