Mounting Instructions
1. Insert the unit into the rack, aligning the mounting bracket holes with those in the rack.
2. Secure the switcher to the rack using the supplied bolts.
Battery and Power Precautions
The matrix switcher is provided with a permanently installed (factory‑soldered in place)
lithium battery. The battery maintains the real time clock in the event of power failure or
extended storage periods and does not affect the normal operation of the switcher. If the
battery becomes ineffective, return the switcher to Extron for repair.
WARNING: Explosion hazard — There is a danger of explosion if the battery is
incorrectly replaced. Do not attempt to remove or replace the internal battery.
ATTENTION:
• This unit uses double pole/neutral fusing.
• Do not operate the equipment with only one power supply cord connected.
Removing and Installing the I/O Board or Blank Panel
WARNING: Risk of serious physical injury — The FOX matrix switchers fiber optic
I/O boards output continuous invisible light, which may be harmful to the eyes; use
with caution.
• Do not look into the fiber optic cable connectors or into the fiber optic cables
themselves.
• Plug the attached dust caps into the optical transceivers when the fiber cable is
unplugged.
NOTES:
• As factory configured, the fiber optic I/O boards are either 100 percent singlemode
or 100 percent multimode, but you can remove a fiber optic transceiver module
(one input and one output) of one transmission mode and replace it with a block of
the other transmission mode.
You can mix transmission mode transceiver modules on a fiber optic I/O board,
provided that you ensure that each fiber cable and connected devices are the
appropriate transmission mode for the transceiver module. Typically, singlemode
fiber has a yellow jacket and multimode cable has an orange or aqua jacket.
• For proper cooling and air flow, boards or blank panels should be installed in all
locations during normal switcher operations.
