Chapter 5 Installing Memory in the Router

Installing and Configuring Flash Memory Cards in Cisco 3620, Cisco 3640, and Cisco 3660 Routers

Perform this procedure to install a Flash memory card:

Step 1 Verify that the Flash memory card’s write-protect switch is OFF. The write-protect switch is at the top left edge of the card, when you view it with the label side toward you. (See Figure 5-28.)

Step 2 Locate the PCMCIA slots, labeled 1 and 0, at the bottom right corner of the front panel of the chassis. (See Figure 5-29and Figure 5-30.)

Note You can install a single Flash memory card in either slot, and you can install Flash memory cards in both slots.

Step 3 For Cisco 3620 and Cisco 3640 routers, insert the connector end of the Flash memory card, label side up, into one of the PCMCIA slots until the card is seated in the connector. (See Figure 5-29.)

Note In Cisco 3620 and Cisco 3640 routers, the card does not fit completely into the router; part of the card projects from the slot.

For Cisco 3660 routers, rotate the ejector button outward, and then insert the connector end of the Flash memory card, label side up, into the PCMCIA slot until the card is seated in the connector. (See Figure 5-30.)

Step 4 For Cisco 3660 routers, rotate the ejector button back in, to prevent accidental ejection of the card.
