Summary
Operates at 50 MHz. It handles network interfaces and
network protocol processing for supported media and
protocols and manages data down to the packet level.
32 MB (upgradeable to 64 MB) of instruction and data
memory and 8 MB of shared (packet) memory provides
optimal performance compared with single memory-based
systems. See Appendix A for upgrade instructions.
64 MB of instruction and data memory and 16 MB of
shared (packet) memory provides optimal performance
compared with single memory-based systems.
PCMCIA flash memory provides non-volatile, non-rotating,
high-capacity base media for software.
Allows update of firmware without swapping PROMs.
Allows stamping of date and time for error logs regardless
of the state of the network.
Allows voltage and temperature monitoring of the DPE
module.
