The SDRAM DIMM comes installed with your Cisco 7401ASR router. To replace the SDRAM, follow these instructions:

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the system board with your hand or any metal tool, or you could shock yourself.

Removing the Cover

Step 1 Power off the router.

Step 2 Remove any cables from the Cisco 7401ASR router, including the power cables. For AC power supplies, unplug the AC power cord from the power outlet. For DC power supplies, to ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Step 3 Remove the Cisco 7401ASR router from the rack, if it is rack-mounted.
