Installing the FastIron GS Chassis

WARNIN G: 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.
WARNIN G: Make sure that the power source circuits are properly grounded, then use the power cord supplied
with the device to connect it to the power source.
WARNIN G: If the installation requires a different power cord than the one supplied with the device, make sure
you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your
country. The mark is your assurance that the power cord can be used safely with the device.
Preparing the Installation Site

Cabling Infrastructure

Ensure that the proper cabling is installed in the site. See “Chassis Specifications” on page6-2 or
www.foundrynetworks.com for a summary of supported cabling types and their specifications.

Installation Location

Before installing the device, plan its location and orientation relative to other devices and equipment. Allow at
least 3" of space at the front of the device for the twisted-pair, fiber-optic, and power cabling. Also, allow a
minimum of 3" of space between the sides and the back of the device and walls or other obstructions.
Installing an Additional Power Supply
The FGS ships with one AC or DC power supply. If desired, you can install a second supply for added power or for
redundancy (if applicable). The illustration below shows the rear panel of an AC power supply.
If you need to install a second power supply, it may be easier to install it before mounting the device, although the
power supplies are “hot swappable” and can be installed or removed after the device is mounted and powered on.
CAUTION: Remove the power cord from a power supply before you install it in or remove it from the device.
Otherwise, the power supply or the device could be damaged. The device can be running while a power supply is
being installed or removed, but the power supply itself should be disconnected from the power source.
