NEMI Location Placement
The physical location of the NEMI module (either master or slave) in the chassis
is the same. See Figure 1-17.

NEMI Ports
Each NEMI module contains four ports:
• One serial port (RS-232)
• One Ethernet port (10BASE-T)
• Two bus interconnect ports
You can use the Ethernet port to connect the NEMI to the network or to another
computer. You can use the serial port to connect the NEMI to a computer for
initial system configuration using PPP, for connection to modems or terminal
servers, or for interconnecting two NEMI modules.
You can use bus interconnect ports to connect the NEMI-master or the
NEMI-slave with the corresponding DEMI module using external bus cables. The
front panel of the NEMI is shown in Figure 1-18.
