requirements:

• For 10/100 and 10/100/1000 ports, cable lengths from the switch to connected

devices are up to 100 meters.

• For 100BASE-FX ports, the cable length from a switch to an attached device

does not exceed 6562 feet (2 kilometers) for full-duplex connections.

• For 1000BASE-X GBIC ports, cable lengths from the switch to the connected

devices are up to 100 kilometers. For specific cable lengths, refer to the GBIC

documentation.

• For 1000BASE-T GBIC ports, cable lengths from the switch to the connected

devices are up to 100 meters. For specific cable lengths, refer to the GBIC

documentation.

• For GigaStack GBIC ports, cable lengths from the switch to the connected

devices are up to 1 meter. For specific cable lengths, refer to the GigaStack

GBIC documentation.

• Operating environment is within the ranges listed in Appendix A, “Technical

Specifications.”

• Clearance to front and rear panels is such that

–

Front-panel indicators can be easily read.

–

Access to ports is sufficient for unrestricted cabling.

–

Rear-panel power connector is within reach of an AC power receptacle.

• Airflow around the switch and through the vents is unrestricted.

• Temperature around the unit does not exceed 113°F (45°C).

Note If the switch is installed in a closed or multirack assembly, the temperature around

it might be greater than normal room temperature.
