Questions & Answers
What is the Cisco ASR 1000 RP Memory M-ASR1K-EUSB-1GB?
The Cisco ASR 1000 RP Memory M-ASR1K-EUSB-1GB is a 1 GB DRAM module designed to upgrade the route processor on Cisco ASR 1000 series routers, enhancing performance and feature capacity.
Which Cisco ASR 1000 series routers are compatible with M-ASR1K-EUSB-1GB?
The M-ASR1K-EUSB-1GB module is fully compatible with ASR 1001, ASR 1002, ASR 1002-X, ASR 1004, and ASR 1006 routers running a supported IOS-XE release.
What performance benefits does the 1 GB RP memory upgrade deliver?
Upgrading to M-ASR1K-EUSB-1GB boosts routing table capacity, reduces CPU bottlenecks, and enables advanced features like AVC, WAAS, and MPLS-TE on Cisco ASR 1000 platforms.
How do I install the M-ASR1K-EUSB-1GB memory module?
Power down the ASR chassis, open the RP cover, insert the M-ASR1K-EUSB-1GB DRAM module into the designated slot, secure the module, and reboot the router per the hardware installation guide.
Can I install M-ASR1K-EUSB-1GB without disrupting network operations?
No; installing M-ASR1K-EUSB-1GB requires a brief maintenance window because the ASR 1000 route processor must be powered off before memory replacement.
How do I verify that the new RP memory is recognized?
After rebooting, run `show platform hardware qfp active feature profile` or `show memory statistics` in the CLI to confirm the router reports 1 GB of route processor DRAM.
Does M-ASR1K-EUSB-1GB support hot‐swapping?
No; the M-ASR1K-EUSB-1GB DRAM module is not hot‐swappable and requires a complete RP power cycle to install or remove.
What are the technical specifications of the 1 GB RP memory?
The M-ASR1K-EUSB-1GB is a 200-pin ECC DDR2-400 DRAM module, operating at 2.5 V with error-checking and correction features to ensure high reliability.
Is firmware or software upgrade required after installation?
No additional firmware is needed; the ASR 1000 IOS-XE images automatically detect the upgraded memory and adjust feature availability accordingly.
What warranty covers the Cisco ASR 1000 RP Memory?
Cisco provides a one-year limited hardware warranty for M-ASR1K-EUSB-1GB, covering defects in materials and workmanship under normal use conditions.
How does upgrading to 1 GB of RP memory affect licensing?
The memory upgrade does not alter licensing; you must maintain valid Cisco software license(s) for the additional features enabled by the increased DRAM capacity.
Where can I purchase the M-ASR1K-EUSB-1GB module?
You can order the M-ASR1K-EUSB-1GB from authorized Cisco resellers, distribution partners, or via Cisco’s e-commerce portal using SKU M-ASR1K-EUSB-1GB.
How do I troubleshoot recognition issues after installation?
Ensure proper seating of the DRAM module, verify RP firmware is current, and check for POST errors in the router logs using `show logging` or `show platform health`.
What is the typical lead time for delivery?
Delivery time for M-ASR1K-EUSB-1GB depends on stock levels and region, but most orders ship within 3–5 business days from Cisco-authorized warehouses.
Can I mix the 1 GB RP memory with existing memory on the same RP?
No; the Cisco ASR 1000 route processor requires the use of identical 200-pin ECC DRAM modules, so mixing different densities or types is not supported.
How does M-ASR1K-EUSB-1GB impact power consumption?
Adding the 1 GB DRAM module increases route processor power draw by approximately 2 W, which is negligible in standard ASR 1000 power budgets.
