CSMIM2 Installation Guide
1.5.3
Terminal and Communications Access
The CSMIM2 provides terminal and communications access to users on a
local area network. The CSMIM2 can connect up to 7 asynchronous serial
devices to host computers on a LAN.
1.5.4
Backplane Connectivity and Mangement
The CSMIM2, through the use of Repeater Interface Controller (RIC)
technology is capable of operating on any one of the three separate
segments (Ethernet channels A, B or C) located on the Multi Media
Access Center (MMAC) backplane. Channels are initially
user-configured using jumpers but may be changed using software
commands via local management with the EMME or EMM-E6 Ethernet
Management Modules.
1.5.5
System Description
The CSMIM2 is a powerful 32-bit device that comes with an Intel 80486
SXLC2 clock-doubled processor. The CSMIM2 read-only memory
(ROM) contains firmware for performing power-up self-tests and loading
operational code. A non-volatile EEPROM stores the configuration
parameters.
The ROM Monitor is an interactive command interpreter that accesses the
ROM’s functions. ROM Monitor commands are issued through a terminal
connected to the console port on the CSMIM2
.
Using the ROM Monitor
commands, you can:
•
Modify and display a set of EEPROM parameters.
•
Execute interactive diagnostic tests.
•
Receive information and statistics for the hardware configuration and
the network.
•
Boot the CSMIM2 manually.
The CSMIM2 is a diskless device. It obtains operational code either over
the network from a host running Micro Annex Communication Software
Version 9.2.6 or above, another CSMIM2 configured as a load server, or
from self-contained Flash Memory.
