Replacing and Maintaining the Hardware
This chapter provides instructions for maintaining the FastIron compact switch hardware.
WARNING: The procedures in this manual are for qualified service personnel.
Hardware Maintenance
The FastIron compact 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 install or replace the following hardware components as needed:
• Copper and fiber optic modules (SFPs (mini-GBICs) and XFP transceivers)
• Power supplies
• CPU Dual Inline Memory Module (DIMM)
• 10-Gigabit Ethernet module
• Dual Inline Package (DIP) key (Layer 3 upgrade)
Replacing a Power Supply
You can replace a power supply while the FastIron switch is powered on and running. The power supplies are
located in slots at the rear of the FastIron switch.
This section provides information about the following topics:
• Installation precautions and warnings
• Determining which power supply has failed, if necessary.
• Replacing a power supply.
WARNING: Power supplies are hot swappable. However, Foundry Networks recommends that you disconnect
the power supply from AC power before installing or removing the supply. The device can be running while a
power supply is being installed or removed, but the power supply itself should not be connected to a power
source. Otherwise, you could be injured or the power supply or other parts of the device could be damaged.
