To clean the fiber cable connectors, it is recommended that you use a fiber optic
reel-type cleaner. You can purchase this type of cleaner from the following Web
site:

When not using an SFP connector, make sure to keep the protective covering in
place.
Testing connectivity
Test for connectivity by observing the LEDs related to network connection.
Pinging an IP address
To verify that a y-series device can reach another device through the network,
enter a command similar to the following at any level of the CLI.
FCX648SHPOE Switch> ping 192.33.4.7
Syntax: ping <ip addr> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>]
[verify] [no-fragment] [quiet] [data <1-to-4 byte hex#, e.g. abcdef00>] [numeric]
[size <byte>] [brief [max-print-per-sec <num 0-2047>]]
Note: If you address the ping to the IP broadcast address, the device lists the first
four responses.
Observing LEDs
After you install the network cables, you can observe certain LEDs to determine if
the network connections are functioning properly. Table 20 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. For the locations of the LEDs, see “Control features” on page 3.

with the remote port
and user packets are
being transmitted or
received. Off A link is not established with the remote port. You
can do the following:
v
Verify that the connection to the other network
device has been properly made. Also, make certain
that the other network device is powered on and
operating correctly.
v Verify that the port has not been disabled through a
configuration change. You can use the CLI. If you
have configured an IP address on the device, you
also can use the Web management interface or
IronView Network Manager.
v For the combination ports (ports 1~4), check that
the shared SFP port (1F~4F) is not being used.
v If the other actions don't resolve the problem, try
using a different port or a different cable.
