1.128 MB of DRAM is the default DRAM configuration for the GRP.

2.This memory is neither user configurable nor field upgradeable.

3.SIMM socket is wired according to a Cisco design and does not accept industry-standard, 80-pin Flash SIMMs.

4.20-MB Flash memory card is the default shipping configuration.

5.Type I or Type II PCMCIA cards can be used in either PCMCIA slot.

DRAM

The EDO DRAM on the GRP stores routing tables, protocols, and network accounting applications, and runs the Cisco IOS software. The standard (default) GRP DRAM configuration is 64 MB of EDO DRAM, which you can upgrade to 256 MB. Table 1-2lists the DRAM configurations and upgrades.
