Memory cards provide long-term, nonvolatile random-access memory (NVRAM) storage for configuration and data. Table
1-4 lists the memory cards available for the chassis.
Memory Cards
Memory Card
Description
CSC-MC+
Optional memory card with a combination of 4 MB of Flash memory and 32 KB of NVRAM.
Allows remote loading and storage of multiple software images.
Installs on the top of the card cage.
Requires a NVRAM connection to the CSC-MCI, CSC-1R, or CSC-2R card,
or a connection to the CSC-ENVM card.
CSC-MC+ NVRAM is superseded by the CSC-ENVM NVRAM.
CSC-ENVM1
Monitors the chassis interior environment.
Provides 64 KB of NVRAM and 64 KB of shared buffer (Multibus) memory for the chassis. Installs in the
top chassis slot.
Provides an optional connection for the Flash memory card.
CSC-ENVM NVRAM supersedes the CSC-MC+ NVRAM.
1 The CSC-ENVM card is not an optional card. It is the default NVRAM card for the AGS+ and is required in the chassis.
The new CSC-ENVM card installed in your AGS+ chassis uses nonvolatile random-access memory (NVRAM) devices with
built-in lithium batteries. These combination NVRAM/battery devices replace the multiple NVRAM devices and three separate
nickel-cadmium batteries on previous CSC-ENVM cards; otherwise, the CSC-ENVM cards are identical. The three spaces in
the CSC-ENVM card are where the nickel-cadmium batteries were installed, and are intentionally left empty. The performance
and memory capacity of both cards is the same in every respect.
