Port Adapter. The COM2 port can support serial connections for the following dial-up
interfaces:

The COM2 port provides a single DB-9 connector wired for an RS-232 DCE signal. The
COM2 Port Adapter plugs into any NET slot (slots 11 and 12) of the D400. The Redundant
TP Et COM2 Port Adapter plugs into the NET1 slot (slot 11).
