Inserting or Removing Optical Switch
Cassettes (Certain Models Only)
If your unit features optical switch cassettes, you can change the
configuration according to your test needs.
To insert a cassette into the unit:
1. If you are using a fiber management tray, remove the protective
window. For more information, see Working with the Fiber (Patchcord)
Management Tray on page 36.
2. Turn off the unit and disconnect it completely from the power sources
(turn off both disconnect devices).
3. Put on an antistatic strap and connect it to the connector provided for
that purpose on the front panel of the unit.
4. Loosen the retaining screws on each side of the unit.
5. Pull the unit out of its casing.

AUTION
When removing a cassette, make sure to replace it with another
one so that the front opening of the unit is always filled. Leaving
empty spaces into the opening could allow dust and particles into
the unit, and compromise its optimal operation.
