Maintenance and Modifications
This section describes repairing and reconfiguring the FOX3 Matrix switchers by replacing components.
NOTE:
All the diagrams in the section show the 40x frame, which is similar in function to the 80x frame.
Removing and Installing a Module
Input/Output modules can be added or removed to increase or decrease the I/O configuration (size) of the switcher.
WARNING:
The fiber optic I/O modules of the FOX3 matrix switchers 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.
AVERTISSEMENT:
L'appareil émet une lumière invisible en continu, à utiliser avec precaution.
Ne regardez
pas dans les connecteurs de câble fibre optique sur le panneau arrière ou dans les câbles fibre optique eux-
mêmes.
Branchez les protections contre la poussière dans l'ensemble émetteur/récepteur lorsque le câble fibre optique est
débranché.
ATTENTION:
•
Do not touch the electronic components or the connectors on the backplane or on the circuit boards without being
electrically grounded. Handle circuit boards by their edges only. Electrostatic discharge can damage circuits, even if you
cannot feel, see, or hear it.
•
Ne pas toucher les composants électroniques ou les connecteurs sur la carte mère ou sur les circuits imprimés sans être
électriquement relié à la terre. Manipuler les circuits imprimés en les tenant seulement par leurs bords. Les décharges
électrostatiques (ESD) peuvent endommager l'équipement, même si vous ne pouvez pas le sentir, le voir ou l'entendre.
•
Thumbscrews should be tightened with a tool after both initial installation and subsequent access to the panel.
•
Les vis doivent être serrées avec un outil adapté après la première installation et l’accès postérieur au panneau.
NOTES:
•
On a fiber optic I/O module as delivered from Extron, all transceiver modules are configured the same: either all
multimode or all singlemode. Multimode and singlemode fiber optic I/O modules can be mixed in a FOX3 matrix
switcher, but ensure the proper transmission mode fiber cables are connected to the board.
•
Typically, singlemode fiber has a yellow jacket and multimode cable has an orange or cyan jacket.
•
For proper cooling and air flow, boards or blank panels should be installed in all locations during normal switcher
operations.
•
The FOX3 Matrix Switcher components that are user-replaceable are hot-swappable. The switcher does not need to be
powered down to remove or replace a component.
Remove and replace an I/O module as follows:
1.
Disconnect any connected cables.
2.
Rotate the left and right captive panel screws to
completely loosen the screws (see figure 14).
3.
Gently pull on the captive panel screws to loosen the
module from the backplane.
4.
Slide the module out of the chassis. Place the removed
module on an anti-static surface or in an anti-static
container.
5.
Align the module with the left and right chassis guides.
6.
Gently slide the module into the enclosure. Slide the
module toward the front panel until it meets resistance.
7.
Gently seat the module in the backplane.
8.
Use a screwdriver to tighten the left and right captive
panel screws to lock the module in place.
