Switches:
Up-Link: MDI-X (Media Dependent Interface - Crossover) manual slide
switch, converts RJ-45 port #8 from a regular (=) user segment port to a
crossover (X) up-link port for on-off connection to a backbone or another
cascaded hub.
Stack Enable Switch: Manual slide switch to specify which Stackable
Personal Hub is the base of the stack. Exactly one hub should have its Stack
Enable switch in the “OFF” position (left). All other hubs in the stack should
have their Stack Enable switches set to the “ON” position (right).
Internal Termination Switch (ST80-B only): When switched to the right
position, allows BNC connection without a “tee” connector and a 50 ohm
terminator. When switched to left position, a “tee” connector is required.
LEDs:
PWR: GREEN when Proper DC power supplied to ST80.
COL: YELLOW when a transmit collision occurs on the hub.
LINK/TX (per port): GREEN when link established on port. Flickers as
port transmits packets.
