minimau Page 7 Monday, August 26, 1996 11:02 AM Installation Mini MAU The installation of an Asanté Mini MAU is very simple: 1 Locate the AUI port on the device. The AUI is on the rear of your hub or computer. Externally it consists of the 15 pin AUI connector. 2 3 Connect the Mini MAU to the AUI port. Connect the Ethernet cable to the Mini MAU. Twisted-pair cable (10BaseT) with Mini MAU Connect the 10BaseT Mini MAU to the device’s AUI port.

minimau Page 9 Monday, August 26, 1996 11:02 AM Thin cable (10Base2) with Mini MAU Connect the 10Base2 Mini MAU to the device’s AUI port. Before the 10Base2 Mini MAU is connected to the thin Ethernet cable, there may be a straight-through (barrel) BNC connector in the cable at the location where a node connection is available. Simply remove the barrel connector, and connect a “T” connector to the BNC port on the Mini MAU. The connector slips on, twists, and locks in place.

minimau Page 11 Monday, August 26, 1996 11:02 AM Fiber Connect the 10BaseFL Mini MAU to the device’s AUI port. Connect the Mini MAU fiber connector to the fiber cable with ST connectors. ❖ Note: Check with your network administrator before disconnecting cable. Other users must be warned of the interruption of network operations. Even if the network uses self-terminating media or connectors, users downstream from the break will be affected.

minimau Page 13 Monday, August 26, 1996 11:02 AM Switches for 10BaseT MAU There are three switches on the side on the 10BaseT Mini MAU.The default settings for the switches are identified below. ❏ Heartbeat Enable (HBE)function disabled.
minimau Page 14 Monday, August 26, 1996 11:02 AM ❖ Note: If the MAU is used with a hub or repeater this switch should be disabled.❖ Link Integrity Enabled Test Switch This switch is normally enabled to verify cable link. This switch can be disabled to work with non-10BaseT compliant repeaters and hubs. Polarity Correction This switch, when enabled, inverts the polarity of a signal automatically if a received signal has reverse polarity. Wiring problems cause reverse polarity.

minimau Page 20 Monday, August 26, 1996 11:02 AM Switches for 10Base2 MAU The default settings are identified below: ❏ Termination disabled (1, switch UP) ❏ HBE disabled (1, switch UP) Termination The Mini 10Base2 MAU has a built-in 50ohm termination resistor. This is useful if the user does not have a terminator. If enabled the switch is in the “Down” (0) position and the 50 ohm termination is connected across the BNC.
minimau Page 21 Monday, August 26, 1996 11:02 AM ❖ Note: All Asanté MAUS attached to a hub or repeater should have HBE disabled. For example, if the Mini MAU is attached to an AsantéHub 1012 or 2072.❖ Installing a Mini MAU for the AsantéHub 2072 To install an Asanté Mini MAU into the recessed port on the double-slotted AsantéHub 2072 do the following: 1 2 Unscrew the two ejector screws on each side of the module’s front panel and pull out the module approximately four to five inches from the chassis.
