Although some multiprotocol communications software packages include
Network Control Server (NCS) software for backward compatibility, 3Com no
longer provides technical support for NCS software or servers.
User serviceability
The user can replace or add a 16-port asynchronous module, and replace the
diskette drive (Model CS/3100 only), power supply, private memory chips,
and EPROM.
Model CS/3000 has no diskette drive. This configuration is advantageous in
environments where disk contamination is possible or where users are not
allowed access to system software.
Model CS/3100 has a 3.5-inch internal diskette drive. This model can boot
either over the network or locally from the internal diskette drive.
CS/3000 series servers can be purchased in the following configurations:
Three 16-port asynchronous modules (48 ports)
No 16-port asynchronous modules
The no-module configuration allows you to install one, two, or three 16-port
asynchronous modules (for 16, 32, or 48 ports) now or as your networking
needs expand. For instructions on installing and cabling a 16-port
asynchronous module, refer to Chapter 2, "Installation."
Regardless of the configuration you purchase, you must install one Ethernet
interface module (single-port AUI or RJ-45). For instructions on installing and
cabling an Ethernet interface module, refer to "Single-Port AUI Module".
CS/3000 series servers consist of the following components:
Chassis
Cover
Front panel
Back panel
One or more 16-port asynchronous modules (with cable strain relief
brackets)
