Console and
Auxiliary Ports
If you buy the CS/3000 series server without 16-port asynchronous
modules, blanking plates cover the slots intended for these modules. These
blanking plates are shown in Figure 1-4. For instructions on removing the
blanking plates and installing and cabling the modules, refer to Chapter 2,
"Installation."
The Ethernet interface slot is not covered. For instructions on installing and
cabling Ethernet modules, refer to Chapter 2, "Installation."
The console port allows you to attach a terminal that can be used to:
Provide access to the server's user interface
Modify firmware configuration
Perform memory dumps
Console functions are useful for maintenance and repair (for instance, after a
server crash). For information on attaching a console, refer to "Attaching a
Console".
The auxiliary port is reserved for internal 3Com use and is not operational.
The console and auxiliary ports are horizontally mounted male DB-9 RS-232
connectors. The RS-232 connector associated with these ports is based on
the 9-pin IBM PC AT standard, and is configured as data terminal
equipment (DTE). To connect a terminal or other DTE device, use a null
modem cable. To connect a modem or other data communications
equipment (DCE), use a modem cable.
CAUTION: To eliminate cable noise emission in excess of FCC Part 5, and
CISPR22 (EN55022) specifications for Class A devices, the console cable
should be 100% shielded (Inmac
