APPENDIXC
Connecting to DC Power
This appendix describes how to make DC power connections to the Catalyst 3560V2-24TS-SD switch. 
See “Switch Installation (24- and 48-Port Switches)” and “Switch Installation (8- and 12-Port 
Switches)” for instructions on installing the switch.
Connecting to DC Power 
To connect the Catalyst 3560V2-24TS-SD switch to a DC-input power source, follow the steps in these 
sections:
Preparing for Installation, page C-2
Grounding the Switch, page C-2
Wiring the DC-Input Power Source, page C-5
WarningThis unit is intended for installation in restricted access areas. A restricted access area can be 
accessed only through the use of a special tool, lock and key, or other means of security. 
Statement 1017
NoteWe recommend that you use 18 AWG copper wiring for Network Equipment Building Systems (NEBS) 
installation. This guideline follows the standard guidelines for DC power wiring in the Central Office.
NoteWhen an RPS is connected to the Catalyst 3560V2-24TS-SD switch, the switch is not NEBS compliant.
NoteThe grounding architecture of this product is DC-isolated (DC-I).
CautionTo comply with the intrabuilding lightning surge requirements, intrabuilding wiring must be shielded, 
and the shield for the wiring must be grounded at both ends.

CautionThe Catalyst 3560V2-24TS-SD switch is suitable only for intrabuilding or nonexposed wiring 
connections.
Preparing for Installation
Locate the ground lug and the two number-10-32 screws on the switch rear panel and the DC terminal 
block plug in the DC-switch accessory kit.
Obtain these necessary tools and equipment:
Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound-force inches (lbf-in.) 
or 240 ounce-force inches (ozf-in.) of pressure
Panduit crimping tool with optional controlled cycle mechanism (model CT-700, CT-720, CT-920, 
CT-920CH, CT-930, or CT-940CH)
6-gauge copper ground wire (insulated or noninsulated)
Four leads of 18-gauge copper wire
Wire-stripping tools for stripping 6- and 18-gauge wires
Grounding the Switch
WarningThis equipment must be grounded. Never defeat the ground conductor or operate the equipment in the 
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection 
authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
CautionTo make sure that the equipment is reliably connected to earth ground, follow the grounding procedure 
instructions, and use a UL-listed lug suitable for number-6 AWG wire and two number-10-32 
ground-lug screws.
To ground the switch to earth ground, follow these steps. Make sure to follow any grounding 
requirements at your site.
Step 1Locate and remove the ground lug and the two number-10-32 ground-lug screws from the rear panel of 
the switch. (See Figure C-3 for location.) Use a standard Phillips screwdriver or a ratcheting torque 
screwdriver with a Phillips head. Set the screws and the ground lug aside.
Step 2If your ground wire is insulated, use a wire stripping tool to strip the 6-gauge ground wire to 0.5 
inch (12.7 mm) ± 0.02 inch (0.5 mm), as shown in Figure C-1.

Step 3Slide the open end of the ground lug over the exposed area of the 6-gauge wire.
Step 4Using a Panduit crimping tool, crimp the ground lug to the 6-gauge wire, as shown in Figure C-2.
Figure C-2 Crimping the Ground Lug
Step 5Use the two number-10-32 screws to attach the ground lug and wire assembly to the switch rear panel 
ground connector, as shown in Figure C-3. If you are using an RPS, connect the ground lug as shown in 
Figure C-4.
Step 6Using a ratcheting torque screwdriver, torque each ground-lug screw to 15 lbf-in. (240 ozf-in.)

Wiring the DC-Input Power Source
WarningBefore performing any of the following procedures, ensure that power is removed from the DC circuit. 
Statement 1003
WarningOnly trained and qualified personnel should be allowed to install, replace, or service this equipment. 
Statement 1030
CautionYou must connect the Catalyst 3560V2-24TS-SD switch only to a DC-input power source that has an 
input supply voltage from –36 to –72 VDC. If the supply voltage is not in this range, the switch might 
not operate properly or might be damaged.
CautionThe switch must be installed with 5 A-branch-circuit protection.
NoteThis installation must comply with all applicable codes.
To wire the switch to a DC-input power source, follow these steps:
Step 1Apply tape to the circuit-breaker switch handle, and move the circuit-breaker handle to the off position.
Step 2Locate and remove the terminal block plug (see Figure C-5).
Figure C-5 Terminal Block Plug
Step 3Identify the positive and negative feed positions for the terminal block connection. The wiring sequence 
is positive to positive and negative to negative for both the A and the B feed wires. The switch rear panel 
identifies the positive and negative positions for both the A and B feed wires.
Step 4Using a 18-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power 
source to 0.27 inch (6.6 mm) ± 0.02 inch (0.5 mm), as shown in Figure C-6. Do not strip more than 0.29 
inch (7.4 mm) of insulation from the wire. Stripping more than the recommended amount of wire can 
leave exposed wire from the terminal block plug after installation.

Step 5Insert the exposed wire of one of the four DC-input power source wires into the terminal block plug, as 
shown in Figure C-7. Make sure that you cannot see any wire lead. Only wire with insulation should 
extend from the terminal block.
WarningAn exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure 
that no exposed portion of the DC-input power source wire extends from the terminal block plug. 
Statement 122
Figure C-7 Inserting Wires in the Terminal Block Plug
Step 6Use a ratcheting torque screwdriver to torque the terminal block captive screw (above the installed wire 
lead) to 4.5 lbf-in. (72 ozf-in.), as shown in Figure C-8.
CautionDo not overtorque the terminal-block captive screws. The recommended maximum torque is 4.5 lbf-in.

Step 8Insert the terminal block plug in the terminal block header on the switch rear panel, as shown 
in Figure C-10.
CautionSecure the wires coming in from the terminal block so that they cannot be disturbed by casual contact. 
For example, use tie wraps to secure the wires to the rack.

APPENDIXD
Configuring the Switch with the CLI-Based Setup 
Program
This appendix provides a command-line interface (CLI)-based setup procedure for a standalone switch. 
Review the safety warnings in Chapter 2, “Switch Installation (24- and 48-Port Switches)” and 
Chapter 3, “Switch Installation (8- and 12-Port Switches).”
See the Catalyst 3560 Switch Getting Started Guide for setting up the switch by using Express Setup.
Preparing for Setup
Step 1Remove these items from the shipping container:

Preparing for Setup
Step 2Use the supplied RJ-45-to-DB-9 adapter cable to insert the RJ-45 connector into the console port on the 
switch rear panel, as shown in Figure D-2. 
Figure D-2 Connecting a Switch to a PC
Step 3
Attach the DB-9 female DTE of the adapter cable to a PC serial port, or attach an appropriate adapter to 
the terminal.
Step 4Wait before you power on the switch.
Step 5Before you power on the switch, start the terminal emulation session to see the output from the power-on 
self-test (POST). The terminal-emulation software—frequently a PC application such as Hyperterminal 
or ProcommPlus—makes communication between the switch and your PC or terminal possible. 
Step 6Configure the baud rate and character format of the PC or terminal to match these console port default 
characteristics:
9600 baud
8 data bits
1 stop bit
No parity
None (flow control)
Step 7Connect one end of the supplied AC power cord to the power connector on a switch rear panel. See 
Figure D-2. 
Step 8Connect the other end of the power cable to a grounded AC outlet.
