Troubleshooting Network Connections; Managing Temperature Settings - Foundry Networks ServerIron 4G-SSL User Manual

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:
FastIron> 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.

Troubleshooting Network Connections

• For the indicated port, verify that both ends of the cabling (at the Foundry device and the connected device)
are snug.
• Verify that the Foundry device and the connected 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 the 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.

Managing Temperature Settings

This section describes how to display temperature settings on the ServerIron and how to change the temperature
warning and shutdown levels.
Using the Temperature Sensor
The ServerIron comes with a built-in temperature sensor. The temperature sensor causes the device to generate
a Syslog message and SNMP trap if the temperature exceeds a specified warning level or shutdown level. If the
device's temperature exceeds the safe threshold (shutdown level), the device will shut itself down.
The software reads the temperature sensor according to the chassis poll time, which is 60 seconds by default. If
the temperature equals or exceeds the shutdown temperature for five consecutive polls of the temperature by the
software, the software will shut down the device to prevent damage.
You can use the CLI to do the following:
• Display the temperature of the device
• Change the warning and shutdown temperature levels
• Change the chassis poll time
