The MANAGEMENT Port

The 9-pin, male, Out-of-Band Management (OBM) port labeled MANAGEMENT
functions as a DTE port.

This port enables attachment of a terminal, either local or remote, through a modem
connection. The terminal can be used to configure and monitor the switch.

The Out-of-Band Management port automatically detects the baud rate of the
terminal to which it is attached.

Token Ring Ports

Twenty shielded RJ-45 connectors for Token Ring connection.

— Support for the IBM Cabling System via 150 ohm, shielded twisted-pair

(150 ohm STP); or 100 or 120 ohm unshielded twisted-pair via Category
3, 4, or 5 cables.

— These ports allow half-duplex (HDX) or full-duplex (FDX) connections to

other switches, hubs, or end nodes.

The SmartStack STS16-20D/STS16-20R will automatically sense what type
of Token Ring connection is being employed on each of its ports, whether it is:
