2 Installing Flash Memory SIMMs in the Cisco 2500 Series Routers

Tools and Equipment Required

Following are guidelines for preventing ESD damage:

connected to the wall receptacle. Having the power cord connected ensures a ground path for any

ESD voltages.

proper grounding point or surface. Attach it to the inside bottom of the chassis or to the rear panel

the component is being returned to the factory, immediately place it in a static shielding bag.

Caution To avoid damaging the equipment, periodically check the resistance value of the antistatic

strap. The measurement should be between 1 and 10 megohms (Mohms).

The following tools are required to remove and replace the Flash memory SIMMs on the router:

Step 2 Remove all interface cables from the rear panel of the router.

Warning This warning applies to all models that include a BRI port. Network hazardous voltages

are accessible in the basic rate interface (BRI) cable. If you detach the BRI cable, detach the end

away from the router first to avoid possible electric shock. Network hazardous voltages are also

accessible on the system card in the area of the BRI port (RJ-45 connector), even when power is

OFF. (See Figure 1.)
