Preparing for Installation
Statement 371—Power Cable and AC Adapter
Caution
To comply with the Telcordia GR-1089 Network Equipment Building Systems (NEBS) standard for
electromagnetic compatibility and safety, connect the ethernet cables only to intrabuilding or
nonexposed wiring or cabling.
Caution
To comply with the Telcordia GR-1089 NEBS standard, PoE or non-PoE 10/100/1000 Ethernet port
cables that exit from either the left side or right side of the switch should be routed and tied to the nearest
rack metal hardware.
Note
The grounding architecture of this product is DC-isolated (DC-I).
Installation Guidelines
When you determine where to place the switch, be sure to observe these requirements:
•
The operating environment is within the ranges listed in
Appendix A, “Technical Specifications.”
•
Airflow around the switch and through the vents is unrestricted.
•
Clearance to front and rear panels meets these conditions:
–
You can easily read the front-panel indicators.
–
Access to ports is sufficient for unrestricted cabling.
–
The rear-panel power connector is within reach of an AC power receptacle.
•
Temperature around the unit does not exceed 113°F (45°C).
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. Make sure the cabling is safely away from other devices that might damage the
cables.
•
For copper Ethernet ports, including 10/100 ports, 10/100/1000 ports, and 1000BASE-T SFP
module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).
•
The cables meet the specifications in
, which lists the cable specifications for
1000BASE-X and 100BASE-X SFP modules for the Catalyst 3560 switch. Catalyst 3560 switch
SFP ports use both GLC-GE-100XX and GLC-FE-100XX SFP modules.
When you use shorter lengths of single-mode fiber cable, you might need to insert an inline optical
attenuator in the link to avoid overloading the receiver.
