SW3 - PAUSE DISABLE/ENABLE “OFF/PAUSE”
When the UTP port is operating in Auto-Negotiation mode, it advertises for Pause
based on the Pause Disable/Enable “Off/Pause” DIP-Switch setting. Setting the Pause
DIP-switch to the “Off” position
(factory default) forces the UTP port
to negotiate to No Pause. Setting this
DIP-switch to the “Pause” position
allows the UTP port to negotiate to
Symmetrical Pause, Asymmetrical
Pause or No Pause mode. When the
UTP port is operating in Manual
mode, Pause is disabled.
NOTE: When the Fiber optic port
operates in Auto-Negotiation
mode, the port advertises for
Pause. When the Fiber optic port operates in Manual mode, Pause is disabled.
SW4 - MASTER/SLAVE
When the GX/TM module is installed in a chassis with an
iConverter
Network
Management Module (NMM), set the DIP-switch to the LEFT “M/SL” position (factory
default), the assignment of mastership is automatically negotiated by the installed
management modules. To designate the GX/TM module as the master of the chassis,
set the DIP-switch on the module to the LEFT “M/SL” position, and set the other installed
management modules’ DIP-switches to the RIGHT “SL” position to enable Slave-Only
mode.
SW5 - UTP 10/100 AUTO/MANUAL CROSSOVER “AX/MANX”
The 10/100 Auto Crossover feature is only available when the UTP port is operating in
10/100 Auto-Negotiation mode.
When “AX/MANX” DIP-switch is set to “AX” (factory default), the 10/100 UTP Auto
Crossover feature is enabled. When it is set to “MANX”, the UTP Manual Crossover
DIP-switch is enabled to allow the user to manually set either a Crossover or
Straight-through connection.
SW6 - UTP MANUAL CROSSOVER “=/X”
When this DIP-switch is set to “MANX”, the UTP Manual Crossover Switch is enabled.
Set this DIP-switch to “=” (factory setting) when connecting the UTP port to a workstation,
or set it to “X” when connecting to a hub or switch. Only use this setting in 10/100Mbps
Manual negotiation mode.
SW7, SW8 - RESERVED
These DIP-switches are for factory use only and must always remain in the LEFT
position (factory default).
2) INSTALL MODULE IN CHASSIS AND CONNECT CABLES
a. Carefully slide the module into an open slot in the chassis. Align the module with
the installation guides and ensure that the module is firmly seated against the
backplane. Secure the module by fastening the front panel thumbscrew (push in
and turn clockwise to tighten) to the chassis front. Verify the “Pwr” LED is ON
(indicating the chassis is powered).
b. When using a GX/TM SFP model (8939-0), insert the SFP Fiber transceiver into
the Port 1 SFP receptacle on the GX/TM.
NOTE: The release latch of the SFP Fiber transceiver must be in the closed
position before insertion.
SW3 - UTP SPEED GIGABIT/10-100 “1000/10-100”
When the “1000/10-100” DIP-switch is in the “1000” position (factory default), the
UTP port always operates in 10/100/1000Mbps Auto-Negotiation mode. The UTP
port auto-negotiates to a speed of 10Mbps, 100Mbps or 1000Mbps with the
connected UTP device. In this mode, the UTP “AN/Man” and UTP “100/10” DIP-switches
have no effect.
When the “1000/10-100” DIP-switch is in the “10-100” position and the UTP “AN/Man”
DIP-switch is in the “Man” position, the UTP port operates at the Speed, Duplex and
Pause modes set by the “100/10”, “FDX/HDX” and “Off/Pause” DIP-switches.
When the “1000/10-100” DIP-switch is in the “10-100” position and the UTP “AN/Man”
DIP-switch is in the “AN” position, the UTP port maximum auto-negotiation setting
for the Speed, Duplex and Pause mode is determined by the “100/10,” “FDX/HDX”
and “Off/ Pause” DIP-switches.
SW4 - UTP 100/10MBPS “100/10”
When the UTP “AN/Man” DIP-switch (described above) is in the manual “Man” position,
the “100/10" DIP-switch determines the speed of operation for the UTP port. Set the
“100/10” DIP-switch to match the speed of the connected UTP device.
SW5 - UTP FULL/HALF DUPLEX “FDX/HDX”
Setting the UTP Full/Half-Duplex DIP-switch to the LEFT UTP “FDX” position (factory
default) forces the UTP port to operate in Full-Duplex. Setting this DIP-switch to
“HDX” forces the UTP port to operate in Half-Duplex. Adjust the UTP Full/Half-Duplex
DIP-switch to match the duplex mode of the connected UTP device.

SW1, SW2 - BACKPLANE ENABLE
When the DIP-switch is in the LEFT “DS” position (factory default), the Backplane Port
of the GX/TM is isolated from the chassis’ Ethernet Backplane. When the DIP-switch
is in the RIGHT “EN” position, the Backplane Port is enabled. This allows Ethernet
Backplane connectivity to an adjacent module via the chassis Backplane Link “A” or
“B” depending on the switch setting.
