The Ethernet™ Port Interface Module (EPIM)
The 9C300-1 Environmental Module 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
MMAC-Plus system or a Telnet session into local management. Any standard
Cabletron EPIM can be installed. Refer to Appendix A for detailed information on
the EPIM.
LCD and Keypad
The LCD functions as a “window” into the MMAC-Plus System, allowing users
to navigate through various screens via the five-function keypad.
The LCD is a 4 line by 40 character, backlit liquid crystal visual display.
The five-function keypad is used to scroll through MMAC-Plus information
screens, and to select option fields within each menu and submenu. The keypad
consists of five buttons, four of which are directional to move the cursor; the fifth
is the Enter button, used to make menu selections. Figure 3-6 shows the LCD with
a System Banner Screen and the five-function keypad on the MMAC-Plus
Environmental Module front panel.
