The Ethernet Port Interface Module (EPIM)
The 9C306 System Monitor provides a port for Cabletron Systems EPIMs. The
EPIM provides a direct connection to the internal SMB-10 bus. This connection
can be used for out-of-band graphical SNMP management of the SmartSwitch
9000-6 Slot system or a Telnet session into local management. Any standard
Cabletron Systems EPIM can be installed. Refer to Appendix A for detailed
information on the EPIM.
