To install a fiber optic module, you will need an ESD wrist strap with a plug for connection to a metal surface.
WARNIN G: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
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. For more information, see “Cleaning the Fiber-Optic Connectors” on page 4-6.
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. See Table
4.2 on page 4-7.

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 Foundry chassis. You can also purchase this type of cleaner from the following Website:
http://www.fisfiber.com
When not using an SFP or XFP connector, make sure to keep the protective covering on.
Testing Connectivity
After you install the network cables, you can test network connectivity to other devices by pinging those devices.
You also can observe the LEDs related to network connection and perform trace routes.

Pinging an IP Address

To verify that a Foundry device can reach another device through the network, enter a command such as the
following at any level of the CLI on the Foundry device:
FastIron>ping 192.33.4.7
Syntax: ping <ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>] [size <byte>]
[quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>] [brief]
NOTE: If you address the ping to the IP broadcast address, the device lists the first four responses to the ping.
