Installation Guidelines

When determining where to install the switch, verify that these guidelines are met:

  • Clearance to the switch's front and rear panel should meet these conditions:

    • Front-panel LEDs can be easily read.

    • Access to ports is sufficient for unrestricted cabling.

    • AC power cord can reach from the AC power outlet to the connector on the switch's rear panel.

  • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

  • Airflow around the switch and through the vents is unrestricted. To avoid any flow blockage, we strongly recommend these guidelines:

    • Allow at least 3 in. (7.6 cm) of clearance from the left and the right sides, and the front and rear of the switch.

    • Allow at least 1.75 in. (4 cm) of clearance from the top cover, if you are installing the switch in upright position.

    • Allow at least 3 in. (7.6 cm) of clearance from the top cover, if you are installing the switch.

  • Temperature around the unit does not exceed 122°F (50°C). If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

  • Humidity around the switch does not exceed 95 percent.

  • Altitude at the installation site is not greater than 10,000 feet.

  • For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328 feet (100 meters).

  • Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing contaminant build-up inside the chassis, which can result in system malfunction. You must install this equipment in an environment as free from dust and foreign conductive material (such as metal flakes from construction activities) as is possible.

  • None of the switch models can be deployed outside of the wiring closet. These switches can only be deployed indoors.

Verifying Switch Operation

Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify that it passes POST.

To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug the other end into an AC power outlet.

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. The SYST LED blinks green.

When the switch completes POST successfully, the SYST LED remains green. If a switch fails POST, the SYST LED turns amber.

POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.

After a successful POST, unplug the power cord from the switch and install the switch in a rack, on a wall, on a table, or on a shelf.

Installing SFP Modules

See the switch release notes on Cisco.com for the list of supported SFP modules. Use only Cisco SFP modules on the switch. Each Cisco module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the module meets the requirements for the switch.

For information about installing, removing, cabling, and troubleshooting SFP modules, see the module documentation that shipped with your device.

Installing an SFP or SFP+ Module

Before you begin

When installing SFP or SFP+ modules, observe these guidelines:

  • Do not remove the dust plugs from the modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

  • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.


    Caution

    Removing and installing an SFP or SFP+ module can shorten its useful life. Do not remove and insert any module more often than is absolutely necessary.

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2

Find the send (TX) and receive (RX) markings on the module top.

On some SFP or SFP+ modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection.

Step 3

If the module has a bale-clasp latch, move it to the open, unlocked position.

Step 4

Align the module in front of the slot opening, and push until you feel the connector snap into place.

Step 5

If the module has a bale-clasp latch, close it.

Step 6

For fiber-optic SFP or SFP+ modules, remove the dust plugs and save.

Step 7

Connect the SFP cables.

Figure 15. Installing an SFP Module

Removing an SFP or SFP+ Module

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2

Disconnect the cable from the SFP or SFP+ module. For reattachment, note which cable connector plug is send (TX) and which is receive (RX).

Step 3

Insert a dust plug into the optical ports of the SFP or SFP+ module to keep the optical interfaces clean.

Step 4

If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the latch is obstructed and you cannot use your finger, use a small, flat-blade screwdriver or other long, narrow instrument to open the latch.

Step 5

Grasp the SFP or SFP+ module, and carefully remove it from the module slot.

Step 6

Place the module in an antistatic bag or other protective environment.

Connecting to Fiber-Optic SFP or SFP+ Modules


Warning

Class 1 laser product. Statement 1008


Caution

Do not remove the rubber plugs from the SFP or SFP+ module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light. Before connecting to the SFP module, be sure that you understand the port and cabling stipulations.

Procedure

Step 1

Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.

Step 2

Insert one end of the fiber-optic cable into the SFP or SFP+ module port.

Step 3

Insert the other cable end into a fiber-optic receptacle on a target device.

Figure 16. Connecting to a Fiber-Optic SFP Module Port

Step 4

Observe the port status LED.

The LED turns green when the switch and the target device have an established link.

If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be problem with the adapter installed in the target device.

Connecting to 1000BASE-T SFP

When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.


Note

The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. For configuration information for this feature, see the switch software configuration guide or the switch command reference on Cisco.com.


Caution

To prevent ESD damage, follow your normal board and component handling procedures.

Procedure

Step 1

Connect one end of the cable to the SFP module port. Insert a four twisted-pair, straight-through cable when you connect to servers, workstations, and routers. Insert a four twisted-pair, crossover cable when you connect to switches or repeaters.

Step 2

Connect the other end of the cable to an RJ-45 connector on the other device.

Figure 17. Connecting to a 1000BASE-T SFP Module

1

RJ-45 connector

Step 3

Observe the port status LED.

  • The LED turns green when the switch and the other device have an established link.

  • The LED turns amber while the STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the port LED turns green.

  • If the LED is off, the other device might not be turned on, there might be a cable problem, or there might be a problem with the adapter in the other device.

Step 4

If necessary, reconfigure and restart the switch or other device.

10/100/1000 PoE+ Port Connections

A powered device connected to a PoE port does not receive power:

  • Use the show hardware led port power privileged EXEC command to show the PoE status for all ports.

  • Use the show interfaces privileged EXEC command to see if the port is in error-disabled, disabled, or shutdown. Reenable the port if necessary.

  • Verify that the power supply installed in the switch meets the power requirements of your connected devices.

  • Verify that there is sufficient PoE power budget to provide power to the attached device. Use the show power inline global configuration command to check on the available PoE power budget.

  • Verify the cable type. Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switch by a crossover cable. Replace the crossover cable with a straight-through cable.


    Caution

    Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points or IEEE 802.3af-compliant devices. You must remove any cable or device that causes a PoE fault.

10/100/1000 Ethernet Port Connections

The switch 10/100/1000 Ethernet port configuration changes to operate at the speed of the attached device. If the attached ports do not support autonegotiation, you can manually set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have the 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 Ethernet ports:

  • Let the ports autonegotiate both speed and duplex.

  • Set the interface speed and duplex parameters on both ends of the connection.

Auto-MDIX Connections

The autonegotiation and the auto-MDIX features are enabled by default on the switch.

With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If the attached device does not support autonegotiation, you can manually set the switch interface speed and duplex parameters.

With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly.

If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.
