Both are also functionally identical, providing:
•
Token Ring support on the MMAC Flexible Network Bus (FNB)
•
Selectable Token Ring speeds of 4Mbps and 16Mbps
•
In-band (SNMP) and out-of-band (RS232) management
•
Flash EPROM firmware enhancements via Trivial File Transfer
Protocol (TFTP)
•
LANVIEW LED monitoring and diagnostics system
•
Data and system configuration (Non-Volatile Random Access
Memory, NVRAM) protection
NOTE: Although some earlier version modules' COM ports are labeled
Modem and Console respectively, they also provide the same functionality
as modules with COM ports labeled COM 1 and COM 2.
1.2.1 Module Configuration in the MMAC
The TRMM provides management for single or interconnected Token
Ring networks via the backplane from the MMAC right-most
management slot (lower-most on the MMAC-3). When used in
conjunction with the TRMM (or also, for example, when use with a
EMME), the TRMMIM provides the same management functions as the
TRMM for all boards inserted to its left from any MMAC Media
Interface Module (MIM) slot.
The TRMM and TRMMIM can also be used with other Cabletron modules
to support a range of Token Ring and mixed Token Ring and Ethernet
configurations in the same MMAC hub. Contact Cabletron's Networking
Services Department for information on configuration options.
