-====== 3c588 - 3Com Multiconnect repeater hub ======
-{{networking:3c588-front.jpg?400| 3Com - 3c588}}
-Despite appearances, the 3c588 is just a modular repeater, not a switch.
-{{networking:3c588-close-front.jpg?100|}}
-The BNC module has a jumper internally to terminate the segment so you do not have to use a TEE piece.
-It looks like a screw is available to earth the segment too.  The partition LED light comes
-on solid if the segment is partioned off because of a fault, either a short or an open circuit, basically any deviation from the expected 25 Ohms (a 50 ohm terminator at each end, ie. in parallel)
-Flashing indicates the fault is cleared. The reset switch position clears the fault led.
-Available modules:-
-  * 3-port 10base-T
-  * BNC coax
-  * AUI 15 pin D connector
-Also I have read of a module by Codenoll (FOIRL with ST connectors) but have not heard anything else.
-There is a single controller module with a 9 pin D socket on the front, I believe this was intended for an uplink to a second card cage which was never released.

-Module for Thin Ethernet  10Base-2, this has a jumper on to remove the requirement for a bulky Tee piece and 50 Ohm terminator on the front panel where space may be short if fully populated.
-{{networking:3c588-coax.jpg?200|}}
-Module for AUI, this could have a AUI module fitted to convert to 10Base-T, 10Base-2 or fibre, or connect directly to a network card with an AUI cable.

-Module with 3x RJ45 10Base-T sockets and status LEDs.
