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.

Note
