CAM Lite 3

Prerequisites

Table 4. Safety

ELECTROCUTION HAZARD!
DANGEROUS AND OR FATAL VOLTAGES ARE PRESENT IN THE ENERGIZED CABINET.
Follow loto steps as given in first section of this document to disable and verify safe voltage levels.

Laser Radiation Hazard!
Invisible laser radiation can be emitted from disconnected fiber-optic cables or connectors.
Do not stare into the beam, point the cable or connector ends at your eyes, or view through optical instruments.

Electrostatic discharge (ESD) can cause permanent damage to electronic components. Observe the following ESD precautions:
- Wear a static wrist strap to ensure that any accumulated electrostatic charge is discharged from your body to the ground.
- Create a common ground for the equipment being worked on by connecting the static-free mat, static wrist strap, and peripheral units to that piece of equipment.

The SFP optical transceiver is very sensitive to ESD. SFP latent failures can occur, in dry climates or low relative humidity, surpassing their ESD protection. Contaminant failures can occur in SFP optics and exposed glass Rx and Tx cable ends. Do not touch the exposed ends on fiber connectors. Leave the dust caps in place until you are ready to install the SFP module. Use the Fiber Optics Cleaning Kit to clean both the SFP and cable end every time they are replaced or swapped from one port to another, or when using a loopback. When working with the SFP optical transceiver or SFP Loopback, also observe the following precautions:
- Always use ESD protection when handling the SFP optical transceiver to prevent early failure.
- Always keep a protective cap on unplugged fiber connections.
- The SFP must be shipped in antistatic packaging. Discard any SFP shipped or stored without proper ESD protection.
For more information on handling and cleaning the SFP transceiver refer to Fiber Optic Cable Devices Installation and Replacement.

note:

The unit can be withdrawn with slide rail.
