Environmental and physical requirements

The optical routing system is mounted in an optical shelf with connections at the
front of the module. For user access to these connections, a minimum of 36 inches
(90 cm) of clearance is required. Keep the area as dust-free as possible.

Electrostatic discharge

To prevent equipment damage, observe the following electrostatic discharge
(ESD) precautions when handling or installing the components.

Ground yourself and the equipment to an earth or building ground. Use a
grounded workbench mat (or foam that dissipates static charge) and a
grounding wrist strap. The wrist strap should touch the skin and be grounded
through a one megohm resistor.

Do not touch anyone who is not grounded.

Leave all components in their ESD-safe packaging until installation, and use
only a static-shielding bag for all storage, transport, and handling.

Warning:

Never look directly at the output of a fiber which contains

muxed CWDM GBICs, especially with a magnifier. Fiber optic
equipment can emit laser light that can injure your eyes.

Caution:

To minimize contamination, keep protective caps on all fiber

optic connectors when not in use. For more information about handling
fiber optic cables, see

“Handling and cleaning fiber optic equipment” on
