AR745 Router
The AT-AR745 router consists of a base CPU card, enclosure, and power
supply. The base CPU card supports two 10/100 autonegotiating Ethernet
LAN (eth) ports and two asynchronous RS-232 ports.
Front and Rear Panels
Front and rear panels of the AT-AR745 router with a Port Interface Card (PIC)
installed in each PIC bay, and an AT-AR040 4-PIC NSM installed in the NSM
bay, are shown in the following figure.
