Description

This 4GB DRAM kit is the default control-plane memory for Cisco ISR 4400 series routers, from the Cisco 4000 Series Integrated Services Routers range. It suits branch and WAN edge deployments where a router needs factory-default or replacement control-plane memory, and it is the base configuration before a memory upgrade.

The module is made up of two matched 2GB DIMMs (2G+2G) that together fill both DIMM slots. On the ISR 4451-X both slots must hold symmetrical DIMMs of the same type and density, so mixed densities or a single DIMM are not supported. The memory serves the control plane only. The data plane uses separate 2GB DRAM (MEM-4400-DP-2G). No licence is required, and the module draws power from the host router.

From this 4GB configuration, upgrade paths are available to 8GB (MEM-4400-4GU8G) and 16GB (MEM-4400-4GU16G) using symmetrical DIMM pairs. Related part numbers include MEM-4400-2G=, MEM-4400-4G=, MEM-4400-8G=, MEM-4400-8GU16G and MEM-4400-4GU16G.

FAQs

Q: Does this memory need a licence?
A: No. The DRAM module requires no licence or subscription.

Q: Can I fit just one DIMM or mix DIMM sizes?
A: No. Both DIMM slots must be populated with DIMMs of the same type and density. A single DIMM or mixed densities are not supported.

Q: How do I upgrade beyond 4GB?
A: Upgrade kits are available from 4GB to 8GB (MEM-4400-4GU8G, 4G+4G) and from 4GB to 16GB (MEM-4400-4GU16G, 8G+8G). Each uses symmetrical DIMM pairs.

Q: Is this the control-plane or data-plane memory?
A: This module is control-plane DRAM. The data plane uses separate 2GB DRAM, part number MEM-4400-DP-2G.

Q: How does this differ from MEM-4400-4G=?
A: MEM-4400-4G is the default 4GB (2G+2G) configuration made up of two 2GB DIMMs. MEM-4400-4G= is the spare part, supplied as a single DIMM.
