Q
Which Cisco routers are compatible with the MEM-2900-2GB=?
A
This module is fully compatible with Cisco Integrated Services Routers ISR 2901, 2911, and 2921, ensuring seamless integration and optimal performance.
Q
How does adding the 2 GB DRAM DIMM improve router performance?
A
Upgrading to 2 GB of DRAM increases packet buffering, enables more concurrent sessions, and supports advanced features like VPN and firewall services without performance degradation.
Q
Is the MEM-2900-2GB= a genuine Cisco spare part?
A
Yes. The MEM-2900-2GB= is an OEM-approved Cisco spare part, manufactured, tested, and certified by Cisco to meet all original equipment standards.
Q
How do I install the 2 GB DRAM DIMM in my Cisco router?
