MPX Serial and Ethernet Management Ports

You can gain access to switch management software through one of the two serial (RS-232)
ports on the MPX or the Ethernet management port. The two serial ports are configured with
9-pin “D” connectors (DB-9) per the IBM AT serial port specification. One port, called the
“modem” port, is male and the other, called the “console” port, is female. See MPX Manage-
ment Connectors on page 2-3 for illustrations of these ports.
The modem port is a Data Terminal Equipment (DTE) connector, which is typically connected
to a modem. You can also connect directly from this port to a PC or terminal with a standard
null-modem cable available in most computer equipment stores.
♦ Note ♦
The modem port is hard-wired for DTE communica-
tion; you do not need to set any jumpers.
The console port is a Data Communication Equipment (DCE) connector, which can be directly
connected to a PC, terminal, or printer.
