WARNING:
All fiber-optic interfaces use Class 1 Lasers.
NOTE:
See “Installation Precautions” on page 3-1 for other hardware installation precautions.
Before installing a fiber-optic module, have on hand an ESD wrist strap with a plug for connection to the ESD
connector on the NetIron MLX Series chassis.
WARNING:
For safety reasons, the ESD wrist strap should contain a 1 meg ohm series resistor.
To install a fiber-optic module into an Ethernet port, do the following:
1.
Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located in the
upper right corner of the chassis front.
2.
Remove the module from its protective packaging.
3.
Remove the metal cover from the port on the interface module’s control panel.
4.
Gently insert the fiber-optic module into the port until the module clicks into place. The fiber-optic modules are
keyed to prevent incorrect insertion.
Cabling a Fiber-Optic Module
To cable a fiber-optic module, do the following:
1.
Remove the protective covering from the fiber-optic port connectors and store the covering for future use.
2.
Before cabling a fiber-optic module, Foundry strongly recommends cleaning the cable connectors and the
port connectors. For more information, see “Cleaning Fiber-Optic Modules”.
3.
Gently insert the two cable connectors (a tab on each connector should face upward) into the port connectors
until the tabs lock into place.
Cleaning Fiber-Optic Modules
To avoid problems with the connection between the fiber-optic module port and the fiber cable connector, Foundry
strongly recommends cleaning both connectors before making this connection. In particular, dust can accumulate
in either connector and cause problems such as reducing the optic launch power.
To clean the fiber cable connectors, Foundry recommends using a fiber-optic reel-type cleaner. You can purchase
this type of cleaner from the following Website:

When not using a fiber-optic module port connector, make sure to keep the protective covering on.
Troubleshooting Network Connections
After you cable the fiber-optic modules, you can observe certain LEDs to determine if the network connections are
functioning properly. Table 4.2 outlines the LEDs related to the network connections, the desired state of each
LED, possible abnormal states of each LED, and what to do if an LED indicates an abnormal state.
