Testing connectivity
Test for connectivity by observing the LEDs related to network connection.
Pinging an IP address
To verify that a ICX 6610 device can reach another device through the network, enter a command
similar to the following at any level of the CLI.
device> ping 10.33.4.7
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. The following table 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.
Network connection-related LED states TABLE 14

(1-24/48) On or
flashing
(Green or
Yellow) A link is
established 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:
• 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.
• Verify that the port has not been disabled
through a configuration change. You can use the
CLI. .
• If the other actions don’t resolve the problem, try
using a different port or a different cable.
