I have a 7206VXR with a NPE-G1. The G1 currently has 256MB (2x128MB) of memory. The memory modules are SMART part # SM5721685D4DZCHMB5.
We ordered 1GB (2x512MB) as an upgrade.
The new memory is SMART part # SM572648FD8DWCLS
They system will not boot with the new memory installed. Power OK LED lights, as do each of the Gigabit EN LEDs but I get no output to the console and no response from the system.
I have tried 2 different sets of 2 memory modules (from the same vendor) and get the same result. The system works fine with the 2x128 chips installed.
Are there any upgrade limitations or restrictions I'm overlooking? All of the Cisco documentation seems to indicate that the NPE-G1 should accept 2x128MB, 2x256, and 2x512 memory modules.
