•External modem

•Point-to-point protocol (PPP) services

•Wide area network

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 Ethernet + COM2 Port Adapter plugs into the NET1 slot (slot 11).

Note: The COM2 Port requires an external modem to provide dial-up functionality. See section “3.11 COM2 Port Adapter” for more information.
