Switches
Active/Passive Switches
A(ctive) and P(assive) switches are provided for the Ring In port and for
the Ring Out port for connection to active ( “A” ) or to passive (“P”) hubs.
ZDL Switch
The ZDL Switch allows selection of automatic speed detection. NOTE:
The default position is ON. The OFF position is used for connecting non-
802.5 compliant equipment, such as the Hewlet Packard token ring tester.
NOTE: The StackMaster™TR 16-Port Hub must be reset when the ZDL
switch position is changed.
Reset Switch
A reset switch is located on the front of the StackMaster™TR 16-Port Hub.
The reset switch reinitializes the StackMaster™TR 16-Port Unit. If the
SNMP Management Board is installed in the StackMaster™TR 16-Port
Unit and the StackMaster™TR 16-Port Unit is installed at the top of a
Stack, the reset switch reinitializes the entire Stack.
