Hub Back Panel Features

As shown in Figure 12, the back panel features of the AT-TS12FS series

hubs include:

❑ Interrepeater bus connector that attaches the TurboStack module

to the backplane bus in a concentrator chassis

❑ Status indicators providing information on the hub as a whole; for

convenience, these LEDs appear on both the front and back panels

of each hub

Note

TurboStack hubs without management do not have a firmware cassette

port. In a department concentrator configuration, management is provided

by the Master module through the chassis backplane.

Note

Although the AUI port is located on the front panel of the AT-TS12FS/ST,

SC, SM models, it resides on the back panel of the AT-TS24TRS and

AT-TS24TS models. Hub status LEDs are located on both the front and the

back panels of each Slave module.
