Chapter 2 Installation Preparing for Installation • For GigaStack GBIC module ports, the cable length from a switch to an attached device cannot exceed 3 feet (1 meter). • For Long-Reach Ethernet (LRE) ports, cable-length specifications vary. See the "LRE Port" section on page 1-9. • Operating environment is within the ranges listed in Appendix A, "Technical Specifications." • Clearance to front and rear panels meet these conditions: - Front-panel LEDs can be easily read. - Access to ports is sufficient for unrestricted cabling. - Rear-panel AC power connector on switches other than the LRE switches is within reach of an AC power outlet. - Rear-panel direct current (DC) power connector on the Catalyst 2950G-24-EI-DC switch is within reach of a circuit breaker. - Front-panel AC power connector on the LRE switches is within reach of an AC power outlet. - Front-panel DC power connector on the Catalyst 2950ST-24 LRE 997 switch is within reach of a circuit breaker. • 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. • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. • For sites requiring compliance to Telcordia GR-1089-CORE Intra-building Lightning requirements, all 10/100 and 10/100/1000 ports must be connected with shielded cable grounded at both ends.

Installation
Preparing for Installation
•
For GigaStack GBIC module ports, the cable length from a switch to an attached device cannot
exceed 3 feet (1 meter).
•
For Long-Reach Ethernet (LRE) ports, cable-length specifications vary. See the
“
LRE Port
”
section
on page 1-9
.
•
Operating environment is within the ranges listed in
Appendix A,
“
Technical Specifications.
”
•
Clearance to front and rear panels meet these conditions:
–
Front-panel LEDs can be easily read.
–
Access to ports is sufficient for unrestricted cabling.
–
Rear-panel AC power connector on switches other than the LRE switches is within reach of an
AC power outlet.
–
Rear-panel direct current (DC) power connector on the Catalyst 2950G-24-EI-DC switch is
within reach of a circuit breaker.
–
Front-panel AC power connector on the LRE switches is within reach of an AC power outlet.
–
Front-panel DC power connector on the Catalyst 2950ST-24 LRE 997 switch is within reach of
a circuit breaker.
•
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.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures.
•
For sites requiring compliance to Telcordia GR-1089-CORE Intra-building Lightning requirements,
all 10/100 and 10/100/1000 ports must be connected with shielded cable grounded at both ends.
