Removing Screws from the Switch

If you plan to install the switch in a rack, you must first remove screws in the switch chassis so that mounting brackets can be attached. Figure 2-3 shows how to remove the chassis screws in a fixed-port and a modular port switch.

Attaching the Brackets to a Catalyst 2912 XL, 2924C XL, 2924 XL, 2912MF XL, or 2924M XL Switch

Follow these steps to attach the brackets to a Catalyst 2912 XL, 2924C XL, 2924 XL, 2912MF XL, or 2924M XL switch:

The bracket orientation and screws that you use depend on whether you are attaching the brackets for a 19-, 23-, or 24-inch rack. Use two of the supplied screws to attach each bracket, according to rack size:

• For a 19-inch rack, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.
  
  
• For a 23- or 24-inch rack, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.
  
  

Figure 2-3, Figure 2-5, Figure 2-6, Figure 2-7, and Figure 2-8 show how to attach a bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

Note   Catalyst 2912 LRE XL and 2924 LRE XL switches cannot be mounted in telco racks.

Attaching the Brackets to a Catalyst 2912 LRE XL or 2924 LRE XL Switch

Follow these steps to attach the brackets to a Catalyst 2912 LRE XL or 2924 LRE XL switch:

The bracket orientation and screws that you use depend on whether you are attaching the brackets for a 19-, 23-, or 24-inch rack. Use two of the supplied screws to attach each bracket, according to rack size:

• For a 19-inch rack, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.
  
  
• For a 23- or 24-inch rack, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.
  
  

Figure 2-3, Figure 2-5, Figure 2-6, Figure 2-7, and Figure 2-8 show how to attach a bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

Mounting the Switch in a Rack

After the brackets are attached to the switch, use the four supplied number-12 Phillips machine screws to securely attach the brackets to the rack, as shown in Figure 2-11.

After the switch is mounted in the rack, power the switch as described in "Powering On the Switch and Running POST" section.

Attaching the Optional Cable Guide

We recommend attaching the cable guide to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack. If the switch is in a 19-, 23-, or 24-inch rack, use the supplied black screw as shown in Figure 2-12 to attach the cable guide to the left or right bracket. The cable guide for the modular switches requires two screws.

Note   The cable guide is not applicable for the Catalyst 2912 LRE XL and 2924 LRE XL switches.

Installing the Switch on a Wall

To attach the switch to a wall, follow the procedures in this section:

• Attaching the brackets to the switch
  
  
• Attaching the switch to a wall
  
  

  ---

  Note   To mount a Catalyst 2912 LRE XL or 2924 LRE XL switch on a wall, you need to obtain two special wall-mount brackets (Cisco part number wallmount-1ru=). To order these brackets, contact your Cisco sales representative.

  ---

Attaching the Brackets to the Switch

The bracket orientation and the screws you use depend on whether you are attaching the brackets for parallel or vertical wall-mounting. Use two of the supplied screws to attach each bracket, according to the following guidelines:

• For parallel wall-mounting, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.
  
  
• For vertical wall-mounting, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.
  
  

  ---

  Note   The Catalyst 2912 LRE XL and 2924 LRE XL switches cannot be mounted vertically on a wall.

  ---

Figure 2-13 and Figure 2-13 show how to attach the brackets to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.

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 2-17.

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 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 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:

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 phone 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 come 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 2   Connect one end of the fiber-optic cable to the 100BASE-FX port on the switch, as shown in Figure 2-18.

Step 3   Connect the other end of the cable to the 100BASE-FX port of the other device.

Step 4   The port LED comes 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 does not come 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 5   Reconfigure and reboot the connected device if necessary.

Step 6   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 Cisco 575 LRE customer premises equipment (CPE) devices through a patch panel. 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   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-M180120-5 (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 2   Referring to the following figure, secure the cable to the switch:

• For a 90-degree connector, see the top of Figure 2-19.
  
  
• For a 12-degree connector, see the bottom Figure 2-19.
  
  

  ---

  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 575 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 575 LRE CPE device, refer to the Cisco 575 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 public system telephone network (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 phone 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 expansion 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 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 back 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 2-20. 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 up 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.
