The Auxiliary (AUX), Serial Data Interface (SDI), and Ethernet connectors
are on the back left-hand side of the chassis. See Figure 17 on
The AUX port connects auxiliary equipment, such as a Power Failure
Transfer Unit (PFTU), to the Chassis system. The SDI connector in the
chassis interfaces three SDI ports using a three-port SDI cable. The Ethernet
connector in the chassis provides a 10 Mbit Ethernet port. The Ethernet port
accepts an industry-standard Medium Access Unit (MAU). Insert the
Ethernet cable into this MAU.
