d. When using a GM4 model with UTP ports or copper transceivers, connect the UTP port
via a Category 5 or better cable to a 10BASE-T, 100BASE-TX or 1000BASE-T Ethernet
device (depending on the conguration of the port).
3) CONFIGURE MODULE VIA COMMAND LINE INTERFACE
To access the Command Line Interface, connect the GM4 RS-232 Serial Console Port to the
COM port of a computer equipped with terminal emulation software such as HyperTerminal.
The Console Port (DCE) is a mini DIN-6 female connector which can be changed to a
DB-9 connector with the included adapter. The GM4 Console Port is a standard RS-232
asynchronous serial interface.
Start HyperTerminal and select the correct COM Port in the HyperTerminal “Connect To:”
window. Set the serial port to the following:
Bits Per Second 57,600 Stop Bits 1
Data Bits 8 Parity NONE
Hardware Flow Control NONE
The Command Line Interface enables detailed conguration of the module.
4) VERIFY OPERATION
Once the module has been installed and congured per steps 1 - 3, verify the module is
operational by viewing the LED indicators.

SW1: P1 AUTO/MANUAL NEGOTIATION “AN / Man”
When this DIP-switch is in the “AN” position (factory default), the port automatically determines
the duplex and pause modes of the connected device. If the connected device cannot provide
the proper signal to indicate its own mode of operation, the DIP-switch should be set to the
“Man” position. When in manual mode, no capabilities are advertised and the port operates
in full-duplex mode.

SW6, SW7, SW8: LINK MODES
The DIP-switches shown in Figure 2, on the previous page, are used to congure the link
modes. It is recommended to keep link mode DIP-switches in the default Down position
during the initial installation. After the circuit has been tested and operational, congure the
module for the desire mode.
DIP-SWITCH BANK 2
The function of DIP-switch Bank 2 is outlined in Figure 4 below.
Switch Position Legend Down (Default) Up
1 A-DS Disable Enable
2 B-DS Disable Enable
3 M/SL Master (Auto Select) Slave
4 ZTP Disable Enable
Figure 4: DIP-switch Bank 2
Page 2 Page 3
SW1 and SW2: Backplane Enable
When these DIP-switches are in the “Disable” position, the Backplane Port of the module is
isolated from the Ethernet Backplane on the chassis. When these DIP-switches are in the
“Enable” position, the Backplane Port is enabled. This allows Ethernet Backplane connectivity
to an adjacent module via the chassis A/B Backplane Link depending on the switch setting.
Enabling backplane A or B will depend where the module is installed in the chassis. When
connecting an odd slot number to an even slot number (referenced from left to right), use
backplane A. When connecting an even slot number to a odd slot number (referenced from
left to right), use backplane B.
SW3: Master/Slave
Setting this DIP-switch to the “Master” position (factory default), allows chassis mastership
to be automatically negotiated by the installed management modules.
When an NMM2 is installed in the chassis, the NMM2 will always be the master, otherwise
the lowest slot number with a management module installed will become the chassis master.
To designate the GM4 module as the master of the chassis when a Network Management
Module (NMM2) is not installed, set the DIP-switch on the module to the Down “M/SL” position,
and set the DIP-switch on the other installed management modules to the Up “SL” position
to enable Slave-Only mode.
SW4: Zero Touch Global
Zero Touch Provisioning (ZTP) allows the module to be automatically congured via standard
protocols: BOOTP, DHCP, and TFTP. Zero Touch is disabled by default. Setting this DIP-
switch to the “Disable” position (factory default) globally disables DHCP and TFTP protocols.
When this DIP-switch is in the “Enable” position, the network parameters of the module are
requested from a DHCP server. This includes the IP conguration parameters and the IP
address of the TFTP server. Once the parameters are received, the module requests the
conguration le from the TFTP server.
2) INSTALL MODULE IN CHASSIS AND CONNECT CABLES
Caution: Use proper ESD protection to reduce the risk of damage to your equipment.
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 rmly 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 GM4 model with SFP ports, insert the SFP ber or copper transceivers
into the SFP receptacles on the module.
NOTE: The release latch of the SFP transceiver must be in the closed (up) position
before insertion.
The GM4 module has the ability to detect the speed and automatically congure the
port to match the speed of approved SFP transceivers. Some SFP ber transceivers
will need to be congured using the portattribute CLI commands to congure the speed
of the port to match the speed of the installed SFP transceiver.
c. Connect the appropriate multimode or single-mode ber cable to the ber port of the
installed module. It is important to ensure that the transmit (TX) is attached to the receive
side of the device at the other end and the receive (RX) is attached to the transmit side.
Single-ber (SF) transceivers operate in pairs. The TX wavelength must match the RX
wavelength at the other end and the RX wavelength must match the TX wavelength at
the other end.
