Chapter 3 Switch Installation (8- and 12-Port Switches)
Preparing for Installation
• 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 Table B-1 on page B-4 , 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.
When the fiber-optic cable span is less than 15.43 miles (25 km), you should insert a 5-decibel (dB)
or 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the
1000BASE-ZX SFP module at each end of the link.
• Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers.
However, these fans and blowers can draw dust and other particles, causing contaminant buildup
inside the chassis, which can result in a system malfunction.
You must install this equipment in an environment as free as possible from dust and foreign
conductive material (such as metal flakes from construction activities).
These standards provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:
– Network Equipment Building Systems (NEBS) GR-63-CORE
– National Electrical Manufacturers Association (NEMA) Type 1
– International Electrotechnical Commission (IEC) IP-20
This applies to all Cisco Ethernet switches except for this compact model:
– Catalyst 3560-8PC switch—8 10/100 PoE ports and 1 dual-purpose port (one
10/100/1000BASE-T copper port and one SFP module slot)
Equipment That You Supply
You need this equipment to install the switch:
• Number-2 Phillips screwdriver
• Drill with a #27 drill bit (0.144-inch [3.7 mm])
You can order an optional cable guard to secure cables to the front of the switch and to prevent accidental
removal. To order a cable guard (CBLGRD-C3560-12PC or CBLGRD-C3560-8PC), contact your Cisco
representative.
The switch has security slots in the left and right side panels. You can install an optional cable lock, such
as the type that is used to secure a laptop, to secure either or both sides of the switch. Cable locks are
available from most computer accessory suppliers.
Installing the switch in a 19-inch rack requires an optional bracket kit that is not included but which you
can order, RCKMNT-19-CMPCT=.
If you want to connect a terminal to the switch console port, you need to provide an RJ-45-to-DB-25
female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) with that adapter from
Cisco.
