Cisco 2621 Routers

Product Numbers:
MEM2620-32FSBOOT=

This document describes the procedures for replacing the BootROM in a Cisco 2620 or Cisco 2621
router. Cisco 2620 and Cisco 2621 routers can be upgraded to support a maximum of 32MB of Flash
memory when using both the Cisco 2600 BootROM version 12.1(3r)T2 (supplied with Cisco p/n
MEM2620-32FSBoot=) and Cisco IOS Release 12.1.3T, 12.2, 12.2T, or later Cisco IOS versions.

Note You can upgrade the BootROM to support 32MB Flash in the following routers: Cisco 2620 and

Cisco 2621.
Cisco 2620XMand Cisco 2621XM routers already support 32MB Flash; they do not require a BootROM
upgrade.
