The connection to the Ethernet is made through a Media Access Unit (MAU) designed to
interface a 10base-5 Ethernet or a 10base-2 Ethernet. The MAU is located in the bottom,
front compartment at the end of the Ethernet Extension Cable. See below.

The 10base-T connection can be made directly into the RJ-45 connection on the rear panel.
• The 10base-T cable from the hub must be long enough to allow for the 15-inch
extension of the electronics module when it is being serviced.
• The 10base-T cable must be tie-wrapped to the existing cable bundle, but do not place
any tie-wraps between the U-shaped bracket and the bend in the cable bundle (back 15
inches).
