Foundry Switch and Router Installation and Configuration Guide
5. Pull the mini-GBIC out of the module.
6. Store the mini-GBIC in a safe, static-free place.

Troubleshooting Network Connections

• For the indicated port, verify that both ends of the cabling (at the device and the connected device) are snug.
• Verify the connected device and device are both powered on and operating correctly.
• Verify that you have used the correct cable type for the connection:
• For twisted-pair connections to an end node, use straight-through cabling.
• For fiber-optic connections, verify that the transmit port on the device is connected to the receive port on
the connected device, and that the receive port on device is connected to the transmit port on the
connected device.
• 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.
• If the other procedures don't resolve the problem, try using a different port or a different cable.

Testing Connectivity

After you install the network cables, you can test network connectivity to other devices by pinging those devices.
You also can 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:
BigIron> 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]
See the Foundry Switch and Router Command Line Interface Reference for information about the parameters.
NOTE: If you address the ping to the IP broadcast address, the device lists the first four responses to the ping.

Tracing a Route

To determine the path through which a Foundry device can reach another device, enter a command such as the
following at any level of the CLI on the Foundry device:
BigIron> traceroute 192.33.4.7
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
[source-ip <ip addr>]
The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests
display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the
Foundry device displays up to three responses by default.
See the Foundry Switch and Router Command Line Interface Reference for information about the command
syntax.
