Testing Connectivity - Foundry Networks ServerIron 4G-SSL User Manual

• Install a fiber optic module (SFP transceiver or mini-GBIC for Gigabit Ethernet ports)
• Cable the fiber optic module
Installing a Fiber Optic Module
You must install a fiber optic module (SFP) in each Gigabit Ethernet fiber port you want to use.
You can install a new copper or fiber optic module in a port while the FastIron Stackable device is powered on and
running.
Before installing one of these modules into the port, have the following on hand:
• An ESD wrist strap with a plug for connection to a metal surface.
WARNING: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
To install a copper orfiber 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 copper or 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 4-17.
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 4.1 on page 4-18.
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:
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]
