Management Options
Cisco IOS CLI
The switch CLI is based on Cisco IOS software and is enhanced to support desktop-switching 
features. You can fully configure and monitor the switch and switch cluster members from the CLI. 
You can access the CLI either by connecting your management station directly to the switch console 
port or by using Telnet from a remote management station. See the Catalyst 3560 Switch Command 
Reference on Cisco.com for more information.
For setup instructions that use the CLI, go to Appendix D, “Configuring the Switch with the 
CLI-Based Setup Program.”
CiscoView application
The CiscoView device-management application displays the switch image that you can use to set 
configuration parameters and to view switch status and performance information. The CiscoView 
application, which you purchase separately, can be a standalone application or part of a Simple 
Network Management Protocol (SNMP) platform. See the CiscoView documentation for more 
information.
SNMP network management 
You can manage switches from a SNMP-compatible management station that is running platforms 
such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of 
Management Information Base (MIB) extensions and four Remote Monitoring (RMON) groups. See 
the switch software configuration guide on Cisco.com and the documentation that came with your 
SNMP application for more information.
Network Configurations
See the switch software configuration guide on Cisco.com for an explanation of network configuration 
concepts. The software configuration guide also provides examples of network configurations that use 
the switch to create dedicated network segments that are interconnected through Ethernet connections.

Preparing for Installation
Statement 371—Power Cable and AC Adapter
CautionTo 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. 
CautionTo 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.
NoteThe 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 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.

Chapter 2      Switch Installation (24- and 48-Port Switches)
Verifying Switch Operation
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) 
Box Contents
The switch getting started guide on Cisco.com describes the box contents. If any item is missing or 
damaged, contact your Cisco representative or reseller for support.
Tools and Equipment
You need to supply a number-2 Phillips screwdriver to rack-mount the switch.
Verifying Switch Operation
Before you install the switch in a rack, on a wall, or on a table or shelf, you should power the switch and 
verify that the switch passes POST. See Section 3, “Running Express Setup,” in the getting started guide 
for the steps required to connect a PC to the switch and to run Express Setup. 
If your configuration has an RPS, connect the switch and the RPS to the same AC power source. See the 
“Cisco RPS” section on page 1-19, and see the Cisco RPS documentation for more information. 
NoteWhen you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode 
during normal operation. 
To power on the switch, connect one end of the AC power cord to the AC power connector on the switch, 
and connect the other end of the power cord to an AC power outlet.
WarningAttach only the following Cisco RPS model to the RPS receptacle: 
PWR-RPS2300, PWR675-AC-RPS-N1=. Statement 370

Chapter 2      Switch Installation (24- and 48-Port Switches)
Installing the Switch
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the 
switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When 
the switch begins POST, the System, RPS, Status, Duplex, and Speed LEDs turn green. The System LED 
blinks green, and the other LEDs remain solid green. 
When the POST completes successfully, the System LED remains green. The RPS LED remains green 
for some time and then reflects the switch operating status. The other LEDs turn off and then reflect the 
switch operating status. If a switch fails POST, the System LED turns amber. 
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
Powering Off the Switch
After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a 
wall, on a table, or on a shelf as described in the “Installing the Switch” section on page 2-7.
