Foundry FastIron LS Layer 2 Compact Switch Hardware Installation Guide
5 - 4 © 2007 Foundry Networks, Inc. September 2007
To change the shutdown temperature, enter a command such as the following at Privileged EXEC level of the CLI:
FLS648 Switch# temperature shutdown 57
Syntax: temperature shutdown <value>
The <value> can be 0 – 125.
Changing the Temperature Polling Interval
The software reads the temperature sensor and polls other hardware sensors according to the value set for the
poll time, which is 60 seconds by default. You can change the poll time using the CLI.
To change the poll time, enter a command such as the following at the global CONFIG level of the CLI:
FLS648 Switch(config)# chassis poll-time 200
Syntax: chassis poll-time <value>
The <value> can be 0 – 65535.
Displaying Management Module CPU Usage
You can display the amount of the management module’s CPU in use. To do so, enter the following command at
any level of the CLI:
Syntax: show cpu
Hardware Maintenance Schedule
The FastIron switch requires minimal maintenance for its hardware components. Foundry recommends cleaning
the fiber-optic connectors on a fiber-optic port and the connected fiber cable each time you disconnect the cable.
Otherwise, you can replace the following hardware components as needed:
• Copper and fiber optic modules (SFPs (mini-GBICs) and XFP transceivers)
• 10-Gigabit Ethernet module
Installing or Replacing a 10-Gigabit Ethernet Module
The 1-port and 10-Gigabit Ethernet modules are optional. You can order the FastIron LS with a 10-Gigabit module
installed at the factory, or you can later upgrade your device.
This section provides the steps for installing, removing, and replacing the 10-Gigabit Ethernet module. You will
need the following tools to perform these procedures:
• #2 Phillips-head screwdriver
• Electrostatic Discharge (ESD) kit.
