TurboStack Hubs with Management
55
By setting the MDI/MDI-X switch to MDI, you can connect two hubs via
standard straight-through cable. The switch affects Port 1 only; you can
continue to use Ports 2 through 24 for network connections via straight-
through cable, no matter which way you set the MDI/MDI-X switch.
If you connect a straight-through cable (or any cable for that matter)
between two hubs (or any two nodes) and the network, LEDs do not
indicate a link condition, you can change the MDI/MDI-X switch. The
repeater will not be damaged if the MDI switch is in the wrong position.
Port Indicators
The port indicators on the AT-TS24TR front panel provide visual
diagnostic and activity information for network analysis. The AT-TS24TR
provides a central bank of indicators for box-level monitoring.
As shown in Figure 53, each 10BASE-T port supports the following
indicator functions with one dual-color front panel LED per port:
