Installation Guidelines
Before installing the switch, verify that these guidelines are met:
•For Ethernet ports, including the 10/100, the 10/100/1000 dual-purpose, and 1000BASE-T SFP module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).
•For cable requirements for SFP module connections, see the "Cable Pinouts" section.
•Operating environment is within the ranges listed in "Technical Specifications."
•Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling.
•AC-power cord reaches from the power outlet to the connector.
•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.
Note If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.
•Before you connect the switch to a power source, note the power consumption specifications in "Technical Specifications."
Verifying Switch Operation
Before installing the switch in a rack, on a wall, on a table, or on a shelf, you should power the switch and verify that the switch passes the power-on self-test (POST).
•To power on the Cisco ME 3400E-24TS-M and Cisco ME 3400EG-12CS-M, see Chapter 3 "Installing and Removing AC- and DC-Power-Supply Modules."
•To power on the Cisco ME 3400EG-2CS-A, 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. (See Figure 2-1.)
Figure 2-1 Cisco ME 3400EG-2CS-A Rear Panel
When the switch begins POST, the System LED blinks green, and the other LEDs remain solid green. When the switch passes POST, the System LED becomes solid green. The other LEDs turn off and return to their operating status. If the switch fails POST, the System LED is solid amber.
Note Contact Cisco Systems immediately 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.

Installing and Removing SFP Modules
Installing SFP Modules
Figure 2-16 shows an SFP module that has a bale-clasp latch.
We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached because of the potential damage to the cables, the cable connector, or the optical interfaces in the SFP module. Disconnect all cables before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.
Figure 2-16 SFP Module with a Bale-Clasp Latch
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 that identify the top side of the SFP module.
On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX).
Step 3 Align the SFP module in front of the slot opening and push until you feel the connector on the module snap into place in the rear of the slot (see Figure 2-17).
Figure 2-17 Installing an SFP Module into an SFP Module Slot
Step 4 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use.
Do not remove the dust plugs from the fiber-optic 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.
Step 5 Insert the cable connector into the SFP module:
•For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the SFP module.
•For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module.
Note When connecting to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 or higher cable.
Removing SFP Modules
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 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 module to keep the optical interfaces clean.
Step 4 Pull the bale out and down to eject the module.

Bale clasp |
Step 5 Grasp the SFP module, and carefully remove it from the module slot.
Step 6 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.
Step 7 Place the removed SFP module in an antistatic bag or other protective environment.
Inserting and Removing the SFP Module Patch Cable
To insert an SFP module patch cable into the SFP module slot, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Insert the SFP module patch cable into the slot until you feel the connector on the cable snap into place in the rear of the slot (see Figure 2-19).
Figure 2-19 Inserting an SFP Module Patch Cable into an SFP Module Slot
Step 3 Repeat these steps for the second switch to which you want to connect the first switch.
Figure 2-20 Connecting Two Switches with an SFP Module Patch Cable
Removing the SFP Module Patch Cable
To remove an SFP module patch cable from the SFP module slot, release the connector, and pull it from the SFP module slot.
Connecting to the 10/100 and 10/100/1000 Ports
The switch 10/100 and 10/100/1000 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 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, 100BASE-TX, or 1000-BASE-T devices:
Step 1 When connecting to workstations, servers, and routers, connect a straight-through cable to an RJ-45 connector on the front panel. (See Figure 2-21.) When connecting to switches or repeaters, use a crossover cable. (See the "Cables and Adapters" section for cable-pinout descriptions.)
Note You can use the mdix auto interface configuration command in the CLI to enable the automatic medium-dependent interface crossover (auto-MDIX) feature. The switch then detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.
Step 2 Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on when both devices have established link. (See Figure 2-21.)
Figure 2-21 Connecting to an Ethernet Port
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 Chapter 4 "Troubleshooting," for solutions to cabling problems.
Note On user network interface (UNI) ports, the port LED is green after the link is established. It does not turn amber because STP is not supported.
Step 3 Reconfigure and reboot the connected device, if necessary.
Step 4 Repeat Steps 1 through 3 to connect each device.
Connecting to Fiber-Optic SFP Modules
|
Warning Class 1 laser product. Statement 1008
|
Do not remove the rubber plugs from the 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 in the "Installation Guidelines" section and in the "SFP Modules" section. See "Connector and Cable Specifications," for information about the LC on the SFP module.
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 module port (see Figure 2-22).
Figure 2-22 Connecting to a Fiber-Optic SFP Module Port
Step 3 Insert the other cable end into a fiber-optic connector on a target device.
Step 4 Observe the port status LED.
The LED turns green when the switch and the target 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 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. See Chapter 4 "Troubleshooting," for solutions to cabling problems.
Step 5 If necessary, reconfigure and restart the switch or target device.
Connecting to 1000BASE-T SFP Modules
Follow these steps to connect a Category 5 or higher cable to a 1000BASE-T SFP module (see Figure 2-23):
Figure 2-23 Connecting to a 1000BASE-T SFP Module
|
|
RJ-45 connector |
To prevent ESD damage, follow your normal board and component handling procedures.
Step 1 When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover cable.
Note When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.
You can use the mdix auto interface configuration command in the CLI to enable the automatic medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.
Step 2 Insert the other cable end in an RJ-45 connector on a target device.
Step 3 Observe the port status LED.
The LED turns green when the switch and the target 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 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. See Chapter 4 "Troubleshooting," for solutions to cabling problems.
Step 4 If necessary, reconfigure and restart the switch or target device.
Connecting to Dual-Purpose Ports
Step 1 Insert an RJ-45 connector or an SFP module in the port. See Figure 2-24.
For more information about RJ-45 connectors and SFP modules, see the "Connecting to the 10/100 and 10/100/1000 Ports" section and the "Connecting to Fiber-Optic SFP Modules" section.
Figure 2-24 Connecting to a Dual-Purpose Port
Step 2 Connect the other end of the cable to the other device. The switch automatically detects the connection and configures the port.
By default, the switch detects that either an RJ-45 copper connector or a fiber-optic SFP module in a dual-purpose port and configures the port accordingly. You can change this setting and configure the port to recognize only an RJ-45 connector or only an SFP module by using the media type interface configuration command. For more information, see the switch command reference.
Where to Go Next
You can use the default configuration or use any of the management options described in the "Management Options" section to change the switch settings.
