Description

This 2GB DRAM memory module is a single DIMM for the Cisco ISR 4400 Series, part of the Cisco 4000 Series Integrated Services Routers. It is intended for replacing or expanding control-plane and services-plane memory on ISR 4451-X and ISR 4431 branch and WAN routers.

The module provides 2GB of capacity in one DIMM. The ISR 4400 platform uses DDR3 ECC DRAM, and the control and services plane ships by default with 4GB on both the ISR 4451-X (2 x 2GB DIMMs) and the ISR 4431. Control-plane memory can be upgraded to a maximum of 16GB on these platforms. The data plane is fixed at 2GB and is not upgradable, and it uses a separate part, MEM-4400-DP-2G, so this module is for the control plane only.

The two DIMM slots must be populated with the same density, as mixed densities or single-slot use are not supported on the ISR 4451-X. Memory is a passive component powered by the host router and needs no licence.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Which routers does this memory module fit?
A: It fits the Cisco ISR 4451-X and ISR 4431 from the ISR 4400 Series, where it is used as control-plane memory.

Q: Can I use it to upgrade the data plane memory?
A: No. The ISR 4400 data plane is fixed at 2GB and is not upgradable. The data-plane part is MEM-4400-DP-2G.

Q: Do the two DIMM slots need matching memory?
A: Yes. Both slots must be populated with the same DIMM type and density. Mixed densities or single-slot use are not supported on the ISR 4451-X.

Q: What is the maximum control-plane memory on the ISR 4400?
A: The ISR 4451-X and ISR 4431 support up to 16GB of control and services-plane memory.

Q: Does this memory module need a licence or power supply?
A: No. It needs no licence and is powered by the host router.
