4 MB Flash Card for Cisco 3640/3660

This Simmtec flash card provides 4 MB of storage for Cisco 3640 and 3660 routers. It serves network engineers who need to replace or expand the boot flash in these specific chassis. The module plugs directly into the router's PCMCIA slot without extra cabling.

Steady read and write cycles

Under sustained load the card delivers consistent read and write cycles for IOS image storage and configuration backups. It handles repeated file transfers during firmware upgrades without the thermal throttling seen in consumer USB drives. The solid-state design has no moving parts to wear out.

Direct PCMCIA insertion

Installation is a simple slide into the front-access PCMCIA slot on a powered-down router; no tools or driver discs are required. The main risk is inserting the card upside down, which can bend the connector pins. Verify the label orientation before applying pressure.
