PRODUCT BULLETIN, NO. 2727

The Cisco® 3745 Multiservice Access Router continues to meet the demands of new services and larger networks through the support of 512 MB of synchronous dynamic RAM (SDRAM) memory. This allows the Cisco 3745 Multiservice Access Router to support a greater number of services, larger routing tables, and leaves room for future growth.

The Cisco 3745 Multiservice Access Router has two Small Outline-DIMM (SODIMM) memory slots on the motherboard. Each slot can hold one of  these memory sizes:

• 64 MB

• 128 MB

• 256 MB

The default memory in the Cisco 3745 Multiservice Access Router is 256 MB. This is shipped from Cisco Systems ® using two 128 MB SODIMMs.
