Wiring the Protective Ground and DC Power for Alarm Circuits

For instructions on grounding the switch and connecting the DC power, see Grounding the Switch, page 40.

Wiring the External Alarms

The switch has two alarm input and one alarm output relay circuits for external alarms. The alarm input circuits are

designed to sense if the alarm input is open or closed relative to the alarm input reference pin. Each alarm input can be

configured as an open or closed contact. The alarm output relay circuit has a normally open and a normally closed

contact.

Alarm signals are connected to the switch through the six-pin alarm connector. Three connections are dedicated to the

two alarm input circuits: alarm input 1, alarm input 2, and a reference ground. An alarm input and the reference ground

wiring connection are required to complete a single alarm input circuit. The three remaining connections are for the alarm

output circuit: a normally open output, a normally closed output, and a common signal. An alarm output and the common

wiring connection are required to complete a single alarm output circuit.

The labels for the alarm connector are on the switch panel and are displayed in Table 13 on page 60.

Attaching the Alarm Connector to the Switch

Warning: Failure to securely tighten the captive screws can result in an electrical arc if the connector is accidentally

removed. Statement 397

Warning: When you connect or disconnect the power and/or alarm connector with power applied, an electrical arc

can occur. This could cause an explosion in hazardous area installations. Be sure that all power is removed from the

switch and any other circuits. Be sure that power cannot be accidentally turned on or verify that the area is

nonhazardous before proceeding. Statement 1058

To attach the alarm connector to the front panel of the switch:

1. Insert the alarm connector into the receptacle on the switch front panel. See Figure 39 on page 64.

Connecting Destination Ports

These section provide more information about connecting to the destination ports:

„ Connecting to 10/100 and 10/100/1000 Ports, page 64

„ Installing and Removing SFP Modules, page 66

„ Connecting to SFP Modules, page 69

„ Connecting to a Dual-Purpose Port, page 71

Connecting to 10/100 and 10/100/1000 Ports

The switch 10/100/1000 ports automatically 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.

Warning: Do not connect or disconnect cables to the ports while power is applied to the switch or any device on

the network because an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed from the switch and cannot be accidentally be turned on, or verify that the area is

nonhazardous before proceeding. Statement 1070

64

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.

The models that support PoE provide up to four ports of either PoE (15.4 W per port; IEEE 802.3af) or PoE+ (30 W per

port; IEEE 802.3at), depending on the power source used. For more information, see Technical Specifications, page 81.

Caution: To prevent electrostatic-discharge (ESD) damage, follow standard board and component handling procedures.

To connect to 10BASE-T, 100BASE-TX or 1000BASE-T devices, follow these steps:

1. When connecting to workstations, servers, routers, and Cisco IP phones, connect a straight-through cable to an

RJ-45 connector on the front panel. See Figure 40 on page 65.

When connecting to 1000BASE-T-compatible devices, use a twisted four-pair, CAT5 or higher cable.

The auto-MDIX feature is enabled by default. For configuration information for this feature, see the Cisco IE 2000

Switch Software Configuration Guide or the Cisco IE 2000 Switch Command Reference.

The port LED turns on when both the switch and the connected device establish the link.

65

The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for loops. This can

take up to 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.

— There might be a cable problem or a problem with the adapter installed in the attached device. For solutions to

cabling problems, see Troubleshooting, page 75

3. Reconfigure and reboot the connected device if necessary.

4. Repeat Steps 1 through 3 to connect each device.

Installing and Removing SFP Modules

These sections describe how to install and remove SFP modules. SFP modules are inserted into SFP module slots on the

front of the switch. Field-replaceable SFP modules provide the uplink interfaces, send (TX) and receive (RX).

You can use any combination of rugged SFP modules. See Table 2 on page 19 for a list of supported modules. Each SFP

module must be of the same type as the SFP module on the other end of the cable, and the cable must not exceed the

stipulated cable length for reliable communications. See Table 2 on page 19 for cable stipulations for SFP module

connections.

Caution: When you use commercial SFP modules such as CWDM and 1000BX-U/D, reduce the maximum operating

temperature by 59°F (15°C). The minimum operating temperature is 32°F (0°C).

Caution: To prevent electrostatic-discharge (ESD) damage, follow standard board and component handling procedures.

Warning: Do not insert and remove SFP modules while power is on; an electrical arc can occur. This could cause an

explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before

proceeding. Statement 1087

Figure 41 on page 66 shows an LC SFP module with a bale-clasp latch.

Caution: Do not install or remove the LC SFP module with fiber-optic cables attached because of 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.

Installing an SFP Module into an SFP Module Slot

Installing LC SFP Modules

To insert an LC SFP module into the SFP module slot:

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

2. Find the send (TX) and receive (RX) markings that identify the correct 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).

3. Align the SFP module sideways in front of the slot opening.

4. Insert the SFP module into the slot until the connector on the module snaps into place in the rear of the slot. See

Figure 42 on page 67.

5. Remove the dust plugs from the SFP module optical ports and store them for later use.

Caution: Do not remove the dust 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.

6. Insert the LC cable connector into the SFP module.

Installing 1000BASE-T SFP Modules

The 1000BASE-T (copper) SFP transceiver, see Figure 43 on page 68, has a bale-clasp locking mechanism that secures

the transceiver in the module socket. An RJ-45 connector provides the transceiver's interface point to the network.

Closed bale-clasp latch mechanism (locked)

Caution: To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded,

twisted-pair, CAT5 cabling.

When connecting to a 1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through

CAT5 cabling for the SFP transceiver port. When connecting to a 1000BASE-T-compatible switch or repeater, use four

twisted-pair, crossover CAT5 cabling.

To install a 1000BASE-T SFP transceiver:

1.

Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector on the chassis or to a properly

grounded bare metal surface.

Caution: To avoid ESD damage, handle the SFP by its sides; do not touch the connector pins.

2.

Remove the new 1000BASE-T SFP module from its protective packaging.

3.

Check the markings on the SFP transceiver to verify that you have the correct model for your network.

4.

Position the SFP transceiver in front of the port socket opening.

Note: Different Cisco devices have different SFP transceiver socket configurations. Your Cisco device might require

that the SFP transceiver be installed with the bale-clasp either in a latch-up or a latch-down orientation. Verify that

the SFP transceiver is oriented correctly when you position it in front of the port socket.

5.

With the bale-clasp closed (locked), slide the SFP transceiver into the socket until you feel it snap in place in the

socket. You may hear an audible click as the SFP transceiver latch engages in the socket (Figure 42 on page 67).

6.

Connect the network interface cable RJ-45 plug to the SFP RJ-45 connector.

7.

Observe the port status LED:

— Green indicates that the SFP transceiver and the target device established a link.

— Amber indicates that the port is discovering the network topology and searching for loops. This process takes

about 30 seconds, and then the LED turns green.

— Off indicates that the target device might not be turned on, there might be a cable problem, or there might be

a problem with the adapter installed in the target device. Refer to Troubleshooting, page 75 for solutions to

cabling problems.

Removing SFP Modules from SFP Module Slots

To remove an SFP module from a module receptacle:

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

2. Disconnect the LC from the SFP module.

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

4. Unlock and remove the SFP module.

If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed

and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to

open the bale-clasp latch. See Figure 44 on page 69.
