For detailed information about network modules (NMs), WAN interface cards (WICs), and Voice interface cards,
(VICs), see the "NMs, WICs, and VICs for the Cisco 3600 Series, 2600 Series, and 1600 Series" section in this chapter.
Memory, Power Supply, and Cable Options
The Cisco 3600 series uses two types of replaceable or upgradeable memory: DRAM memory and Flash memory. Both types
of memory are implemented with SIMMs. Each router has two Flash SIMM sockets and four DRAM SIMM sockets. In the
standard Flash memory configuration, the first socket contains a 4-MB Flash SIMM, and the second socket is empty. You
can upgrade the Flash memory to 16 MB on both routers. Each Cisco 3600 router ships standard with 32 MB of DRAM. The
Cisco 3640 is expandable to 128 MB of DRAM. The Cisco 3620 is expandable to 64 MB of DRAM.
The Cisco 3600 series routers use a DRAM memory configuration that is different from other Cisco routers. Unlike the Cisco
4000 series routers, for example, which have separate physical locations for processor memory and packet memory, the Cisco
3600 series routers use one pool of DRAM memory. The DRAM is partitioned into processor memory and packet memory
areas. For example, the memory of a 16-MB DRAM configuration is split into 12 MB for processor memory and 4 MB for
the packet memory.
The Cisco 3600 allows you to load new system images using a PCMCIA Flash memory card. You can also load images from
a local or remote PC through the console or auxiliary ports using the Xmodem or Ymodem protocols.
