Hardware Compatibility with Cisco 3620 Routers
Cisco 3620 routers require a minimum PCMCIA controller revision level to recognize ATM OC-3
network modules; otherwise, an error message appears. Cisco 3620 routers installed in the field before
April 1999 contain a Revision C PCMCIA controller, which is not compatible with these modules.
Starting in April 1999, all Cisco 3620 routers shipped from the factory include Revision E PCMCIA
controllers, which are fully compatible with all three ATM OC-3 network modules.
You can identify the version of PCMCIA controller in your Cisco 3620 router by entering the show pci
hardware command in privileged EXEC mode, or by examining the part number on the motherboard.
Supported versions are shown in

The output of the show pci hardware command looks similar to this:
