Testing Network Connectivity; Observing Leds - Brocade Communications Systems FastIron SX Hardware Installation Manual

Testing network connectivity

Testing network 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.
For more information about ping and traceroute commands, refer to the FastIron Ethernet Switch Layer 3 Configuration Guide.

Observing LEDs

After you install the network cables, you can observe certain LEDs to determine if the network connections are functioning properly. The
table below 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.
NOTE
Some modules use combined link and activity LEDs.

Brocade FastIron SX Series Chassis Hardware Installation Guide
Meaning or Action
No link exists 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
transmit port on
the Brocade
device is
connected to the
receive port on
the other network
device, and that
the receive port
on the Brocade
device is
connected to the
transmit port on
the other network
device. If you are
not certain,
remove the two
cable connectors
from the port
connector and
reinsert them in
the port
connector,
reversing their
order.
