Table 2-3. AsantéHub Switches and Switch Settings
Switch Description
A On/Off Switch Turns power to the unit on and off. (Power
condition of a networked unit does not
affect AMS Link Ports.) (i.e.: if an
intermediate hub is powered off, all the
other hubs can still communicate over the
AMS link.)
B Through/End switch
(AMS Link Termination)
Terminates AMS Link connection (see AMS
Link, above). Up = through; down = end.
• If both AMS Link ports are occupied, set
the switch to Through.
• If only one AMS or none Link port is
occupied, set the switch to End.
C PC/Terminal switch
(packet/character
transmission)
Determines transmission by character or
packet for the device connected to the RS-
232 port on the rear panel. Up = open;
down = closed.
• To use local PC-based network
management, or a modem, set the switch
to PC.
• To use a local terminal, set the switch
to Terminal.
