local area network. The Micro-CS can connect up to 7 asynchronous 
serial devices to host computers on a LAN.

System Description
 
The Micro-CS is a powerful 32-bit device that comes with an Intel 80486 
SXLC2 clock-doubled processor. The Micro-CS 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 Micro-CS
 
 
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 Micro-CS manually. 
The Micro-CS 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 Micro-CS configured as a load server, or 
from self-contained Flash Memory.
The Micro-CS has a watchdog timer that is reset by the software at 
regular intervals. The watchdog timer reboots the Micro-CS in the 
unlikely event of an internal software error. This feature allows the 
Micro-CS to run for long periods of time without intervention. 
A modem upgrade for the Micro-CS is available for added functionality. 
It consists of a single daughter card, and can be user installed. The 
upgrade kit can be purchased separately from Cabletron as part number 
CSM-V.34-UGK.
