Figure 2-13 Attaching Brackets for Parallel and Vertical Wall-Mounting for Fixed-Port Switches
Figure 2-14 Attaching Brackets for Parallel and Vertical Wall-Mounting for Modular Switches
Mounting the Switch to a Wall
For best support of the switch and cables, make sure the switch is attached securely to a wall stud or to a firmly attached plywood mounting backboard, as shown in Figure 2-15, Figure 2-16, and Figure 2-28.
Figure 2-15 Mounting a Fixed-Port Switch to a Wall
Figure 2-16 Mounting a Modular Switch to a Wall
After the switch is mounted on the wall, power the switch as described in "Powering On the Switch and Running POST" section.
Powering On the Switch and Running POST
To power on the switch after you install it, follow these steps:
Step 1 Connect one end of the AC power cord to the AC power connector on the switch.
Step 2 Connect the other end of the power cord to an AC power outlet.
As the switch powers on, it begins POST, a series of eight tests that run automatically to ensure that the switch functions properly. When the switch begins POST, the port LEDs turn amber for 2 seconds, and then they turn green. The System LED flashes green, and the RPS LED turns off. As each test runs, the port LEDs, starting with number 1, turn off. The port LEDs for ports 2 to 8 each turn off in turn as the system completes a test.
When POST completes successfully, the port LEDs return to the status mode display, indicating that the switch is operational. If a test fails, the port LED associated with the test turns amber, and the system LED turns amber. If POST fails, refer to "Troubleshooting," to determine a course of action.
POST failures are usually fatal. Call Cisco Systems immediately if your switch does not pass POST.
Connecting to DC Power
To connect the Catalyst 2924M XL DC switch to a DC-input power source, follow the steps in these sections:
•Preparing for Installation
•Grounding the Switch
•Wiring the DC-Input Power Source
Preparing for Installation
Follow these steps before rack-mounting and grounding the switch or wiring it to a DC-input power source.
Step 1 Unpack the shipping box, and verify its contents. In addition to the items described in the Catalyst 2900 Series XL Installation Guide, the switch is shipped with a DC terminal block plug on the switch back panel.
Step 2 Obtain the following necessary tools and equipment:
•Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound-force inches (lbf-in.) of pressure
•Panduit crimping tool with optional controlled cycle mechanism, model CT-700, CT-720, CT-920, CT-930, CT-920CH, or CT-940CH
•6-gauge copper ground wire (insulated or noninsulated)
•Four leads of 12- or 14-gauge copper wire
•Wire-stripping tool(s) for stripping both 6- and 12- or 14-gauge wires
Grounding the Switch
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Warning When installing the unit, the ground connection must always be made first and disconnected last.
Follow these steps to ground the switch to earth ground. Make sure to follow any grounding requirements at your site.
Step 1 Use a standard Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head to remove the two number-10-16 ground-lug screws and the ground lug from the rear panel of the switch. (See Figure 2-17.
Figure 2-17 Removing the Ground-Lug Screws
Step 2 Set the screws and the ground lug aside.
Step 3 If your ground wire is insulated, use a wire-stripping tool to strip the 6-gauge ground wire to 0.5 inch (12.7 mm) ± 0.05 inch (1.27 mm) as shown in Figure 2-18:
Figure 2-18 Stripping the Ground-Lug Wires
Step 4 Slide the open end of the ground lug over the exposed area of the 6-gauge wire.
Step 5 Using a Panduit crimping tool, crimp the ground lug to the 6-gauge wire. (See Figure 2-19.)
Figure 2-19 Crimping the Ground Lug
Step 6 Use the two number-10-16 screws to attach the ground lug and wire assembly to the rear panel of the switch.
Step 7 Using a ratcheting torque screwdriver, torque each ground-lug screw to 15 1bf-in. (or 240 ounce-force inches [240 ozf-in.]). (See Figure 2-20.)
Figure 2-20 Torquing Ground-Lug Screws
Wiring the DC-Input Power Source
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Caution The switch is to be installed with 5A-branch-circuit protection.
Note This installation must comply with all applicable codes.
Follow these steps for wiring the switch to a DC-input power source:
Step 1 Locate and remove the terminal block plug. It is already in the DC power connector on the switch back panel. (See Figure 2-21.)
Figure 2-21 Terminal Block Plug
Step 2 Identify the positive and negative feed positions for the terminal block connection. (See Figure 2-22.) The wiring sequence is return to return and negative to negative for both the A feed wires and the B feed wires. The rear panel of the switch identifies the positive and negative positions for both the A and B feed wires.
Figure 2-22 Positive and Negative Positions on the Switch Rear Panel
Step 3 Using a 12- or 14-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power source to 0.27 inch (6.86 mm) ± 0.05 inch (1.27 mm). (See Figure 2-23.) Do not strip more than 0.29 inches (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.
Figure 2-23 Stripping the DC-Input Power-Source Wire
Step 4 Insert the exposed wire of one of the four DC-input power source wires into the terminal block plug. Make sure that you cannot see any wire lead. (See Figure 2-24.) Only wire with insulation should extend from the terminal block plug.
Warning An 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.
Figure 2-24 Inserting Wires into the Terminal Block Plug
Step 5 Use a ratcheting torque screwdriver to torque the terminal block captive screw (above the installed wire lead) to 4.5 1bf-in. (72 ozf-in.). (See Figure 2-25.)
Caution Do not overtorque the terminal-block captive screws. The recommended maximum torque is 4.5 lbf-in. (72 ozf-in.).
Figure 2-25 Torquing the Terminal-Block Captive Screws
Step 6 Repeat Steps 4 and 5 for the remaining three DC-input power source wires. Figure 2-26 shows the completed wiring of a terminal block plug.
Figure 2-26 Completed Wiring of Terminal Block Plug
Step 7 Insert the terminal block plug into the terminal block header on the rear panel of the switch. (See Figure 2-27.)
Caution Secure the wires coming from the terminal block so that they will not be disturbed by casual contact. For example, use tie wraps to secure the wires to a rack.
Figure 2-27 Inserting Terminal Block Into Switch
Connecting to a 10/100 Port
The switch 10/100 ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage. To maximize performance, choose one of these methods for configuring the 10/100 Ethernet ports:
•Let the ports autonegotiate both speed and duplex.
•Set the port speed and duplex parameters on both ends of the connection.
Follow these steps to connect to 10BASE-T and 100BASE-TX devices:
Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through Category 5 cable to an RJ-45 connector on the front panel (Figure 2-28). When connecting to switches or repeaters, use a crossover Category 5 cable. Pinouts for the cables are described in the "Cable and Adapter Specifications" section.
Figure 2-28 Connecting to a 10/100 Switch Port
Note The switch can connect to a Cisco IP Phone through a straight-through, twisted-pair cable. The rear panel of the Cisco IP Phone might have more than one RJ-45 jack. Use the LAN-to-phone jack to connect the telephone to the switch. Refer to the documentation that came with your Cisco IP Phone for information about connecting devices to it.
Step 2 Connect one end of the cable to the RJ-45 connector of the switch 10/100 port.
Step 3 Connect the other end of the cable to an RJ-45 connector of the other device.
The switch port LED comes on when both the switch and the connected device have established link.
The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This takes about 30 seconds, and then the port LED turns green.
If the port LED does not turn on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See "Troubleshooting," for solutions to cabling problems.
Step 4 Reconfigure and reboot the connected device if necessary.
Step 5 Repeat Steps 1 through 3 to connect to each 10/100 port.
Connecting to a 100BASE-FX Port
Warning Invisible laser radiation may be emitted from the aperture ports of the 100BASE-FX single-mode supervisor engine module. Avoid exposure and do not stare into open apertures.
Warning Avoid exposure to the laser beam.
Caution Do not remove the rubber plugs from the fiber-optic port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the fiber-optic port and cable from contamination and ambient light.
You can connect the 100BASE-FX ports to other 100BASE-FX-compatible network devices, such as servers, routers, and other switches. These ports use a duplex SC connector, and you must provide the 50/125- or 62.5/125-micron multimode fiber-optic cable to connect these ports to other 100BASE-FX devices.
The fiber-optic distances between the switch and the attached device follow.
•If the switch port and the port on the attached device are configured for half-duplex operation, the connection can be up to 412 meters.
•If the switch port and the port on the attached device are configured for full-duplex operation, the connection can be up to 2 kilometers.
Note Speed and duplex-mode autonegotiation is not supported on the 100BASE-FX ports.
To connect a switch 100BASE-FX port to another 100BASE-FX device, follow these steps:
Step 1 Remove the rubber plugs from the port and the rubber caps from the cable connectors.
Step 2 Connect one end of the fiber-optic cable to the 100BASE-FX port on the switch, as shown in Figure 2-29.
Figure 2-29 Connecting to a 100BASE-FX Switch
Step 3 Connect the other end of the cable to the 100BASE-FX port of the other device.
The port LED turns on when both the switch and the connected device have established link.
The port LED is amber while the STP discovers the topology and searches for loops. This takes about 30 seconds, and then the port LED turns green.
If the port LED does not turn on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See Chapter 3, "Troubleshooting," for solutions to cabling problems.
Step 4 Reconfigure and reboot the connected device if necessary.
Step 5 Repeat Steps 1 through 3 to connect each 100BASE-FX port.
Connecting to an LRE Port
Depending on the switch model, you can connect the LRE port to either 12 or 24 LRE customer premises equipment (CPE) devices through a patch panel.
Note You can connect both Cisco 575 LRE CPE and Cisco 585 LRE CPE devices to your LRE switch, and you can hot swap the CPE devices without powering down the switch or disrupting the other switch ports.
If telephone services, such as voice or integrated services digital network (ISDN), use the same cabling as LRE traffic, you must connect the LRE to a plain old telephone service (POTS) splitter.
Note Cisco LRE products are designed to share lines with analog, Integrated Services Digital Network (ISDN), and digital private branch exchange (PBX) switch telephones that use the 0 to 700 kHz frequency range. Digital telephones connected to digital PBX switches that use frequencies above 700 kHz do not work when sharing a line with LRE signals. Due to the proprietary nature of digital PBX switches, some digital PBX switch services use frequencies above 700 kHz. [CSCdu73260]
Note If no other telephone services travel on the same wiring as LRE traffic, the LRE switch connects directly to a patch panel.
Connecting the LRE port to a patch panel or POTS splitter requires a male-to-male RJ-21 cable, Category 3 or above. You can order RJ-21 cables from your cable vendor, or you can order these cables from your Cisco sales representative:
•CAB-5-M120M120-5= (Category 5 cable with 90-degree, male-to-male RJ-21 connectors)
•CAB-5-M180M120-5= (Category 5 cable with 120-degree, male-to-male RJ-21 connectors)
The screws you need to secure the cable to the switch are shipped with the cable. Contact your Cisco sales representative for more information.
To connect the LRE port to a patch panel or POTS splitter, follow these steps:
Step 1 Connect one end of a wiring trunk cable to the RJ-21 connector of the LRE port on the switch. (See Figure 2-30.)
Figure 2-30 Connecting to an LRE Port
Step 2 Referring to Figure 2-30, secure the cable to the switch:
•For a 90-degree connector, see the top of Figure 2-30.
•For a 12-degree connector, see the bottom Figure 2-30.
Note The cable tie is not included with the connector and cable assembly.
Step 3 Connect the other end of the cable to the patch panel or POTS splitter.
Each LRE port status LED turns on when it establishes a link with a Cisco LRE CPE. For more information about the LRE link between the switch LRE port and the CPE, as well as information about the configuration and management of CPE devices, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.
For more information about the Cisco LRE CPE devices, refer to the Cisco LRE CPE Hardware Installation Guide.
If telephone services, such as voice or ISDN, use the same cabling as LRE traffic, the LRE port must be connected to the patch panel through a basic telephone service, also known as plain old telephone service (POTS) splitter. The splitter routes LRE data (high-frequency) and voice (low-frequency) traffic from the telephone line to the switch and private branch exchange (PBX) switch or Public Switched Telephone Network (PSTN).
If the other telephone services are connected through a PBX switch, a Cisco LRE 48 POTS Splitter can be used. The PBX routes voice traffic to private telephone networks and the PSTN. For more information about the Cisco LRE 48 POTS Splitter (PS-1M-LRE-48), refer to the Installation Notes for the Cisco LRE 48 POTS Splitter.
If the installation does not have a PBX, a homologated POTS splitter is required to directly connect to the PSTN. For more information about homologated POTS splitters, contact your Cisco sales representative.
Note If a connection to a telephone network is not required at all, a splitter is not needed, and the switch can connect directly to the patch panel.
Connecting to a Module Port
For information about installing and connecting to modules in the Catalyst 2924M XL and 2912MF XL module slots, refer to the Catalyst 2900 Series XL Modules Installation Guide and the Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide.
Connecting to the Console Port
Use the supplied rollover cable and DB-9 adapter to connect a PC to the switch console port. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see the "Cable and Adapter Specifications" section.
The PC or terminal must support VT100 terminal emulation. The terminal-emulation software—frequently a PC application such as Hyperterminal or Procomm Plus—makes communication between the switch and your PC or terminal possible during the setup program.
Follow these steps to connect the PC or terminal to the switch:
Step 1 Configure your PC- or terminal-emulation software to communicate with the switch through hardware flow control.
Step 2 Configure the baud rate and character format of the PC or terminal to match these switch console port default characteristics:
•9600 baud
•8 data bits
•1 stop bit
•No parity
After you have accessed the switch, you can change the port baud rate to its original setting. See the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide for instructions.
Step 3 Using the supplied rollover cable, connect one end of the rollover cable into the console port, as shown in Figure 2-31. See the "Identifying a Rollover Cable" section for a description of the pinout.

Step 4 Attach the supplied RJ-45-to-DB-9 female DTE adapter to a PC, or attach an appropriate adapter to the terminal.
Step 5 Connect the other end of the supplied rollover cable to the attached adapter.
Step 6 Start the terminal-emulation program.
Where to Go Next
After the switch passes POST, it can operate on its default settings and passwords after you configure IP information on the switch. For information about using the setup program, refer to the Release Notes for the Catalyst 2900 Series XL and Catalyst 3500 Series XL Cisco IOS Release 12.0(5)WC(1).
For information about configuring the switch, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.
