Maintaining the Hardware

To install a fiber optic module, do the following:
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as an
equipment rack) to act as ground.
2. Remove the new module from its protective packaging.
3. Gently insert the fiber optic module into the port until the module clicks into place. The module is 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. See “Cleaning the Fiber-Optic Connectors” on page 6-9.
3. Gently insert the cable connector(s) (a tab on each connector should face upward) into the port connector(s)
until the tabs lock into place.
4. Observe the link and active LEDs to determine if the network connections are functioning properly. For more
information about the LED indicators, see Table 4.2 on page 4-9.
Cleaning the Fiber-Optic Connectors
To avoid problems with the connection between the fiber optic module (SFP (mini-GBIC) or XFP) and the fiber
cable connectors, Foundry strongly recommends cleaning both connectors each time you disconnect and
reconnect them. In particular, dust can accumulate in the connectors and cause problems such as reducing the
optic launch power.
To clean the fiber cable connectors, Foundry recommends using the fiber-optic reel-type cleaner that shipped with
your FastIron chassis. You can also purchase this type of cleaner from the following Website:

When not using an SFP or XFP connector, make sure to keep the protective covering on.
