Cleaning the fiber-optic connectors
To avoid problems with the connection between the fiber optic module (SFP (mini-GBIC)) and the
fiber cable connectors, Brocade 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, Brocade recommends using the fiber-optic reel-type cleaner
that shipped with your FastIron WS CHE1. You can also purchase this type of cleaner from the
following Web site:

When not using an SFP connector, make sure to keep the protective covering on.
Testing connectivity
You can observe the LEDs related to network connection.
Pinging an IP address
To verify that a FastIron WS device can reach another device through the network, enter a
command such as the following at any level of the CLI on the Brocade device:
Brocade>ping 192.33.4.7
Syntax: ping | [source ] [count ] [timeout ] [ttl
] [size ] [quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>]
[brief]
NOTE
If you send the ping to the IP broadcast address, the device lists the first four responses to the ping.
Observing LEDs
After you install the network cables, you can observe certain LEDs to determine if the network
connections are functioning properly.
Table 12 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.
