EXPANDED MEMORY (cont.) For applications where additional memory is required, you can order a
circuit monitor with an optional 512K or 1024K memory expansion card,
resulting in 612K or 1124K, respectively, total nonvolatile memory (100K
base memory plus the expansion card memory). Memory upgrade kits are
also available for most earlier circuit monitors. See Upgrading Existing
Circuit Monitors, page 5.
Requirements for Using System Manager software version 3.02 with Service Update 1, 3.02a with
Expanded Memory Service Update 1, or 3.1 (or higher) is required to take advantage of expan-
sion card memory or the 100K of memory standard on G4 circuit monitors.
Earlier versions of System Manager software will recognize only 11K (the
Series G3 and earlier memory capacity) of available memory.
Also, your circuit monitor must be equipped with firmware version 17.008 or
later to take advantage of expanded memory. The following section tells how
to determine the firmware version shipped with your circuit monitor.
To determine if your circuit monitor firmware version has been updated
with downloadable firmware, see Viewing Configuration Data in Protected
Mode, page 45.
To obtain the latest available firmware revision contact your local Schneider
Electric representative (see Note, page 1.)
Identifying the Series and The circuit monitor series and firmware revision number are printed on a
Firmware Revisions sticker on the top of the circuit monitor enclosure. Figure 1-1 shows a sample
sticker.

Model Numbers Circuit monitor models equipped with an optional memory expansion card
are differentiated from standard models by a suffix—either -512k or -1024k—
added to the model number (table 1-4). As shown in the table, the memory
expansion option is available for model numbers CM-2150, CM-2250,
CM-2350, and CM-2450. The CM-2452 circuit monitor is now obsolete and
has been replaced by the CM-2450-512k, which has more memory at a lower
price than the CM-2452. However, existing CM-2452 circuit monitors can be
upgraded as detailed on the following page.
