Running Boot Fast

When the switch powers on, it automatically initiates a boot fast sequence. The boot fast sequence allows the switch to boot up in less than 60 seconds. To test the switch, follow the steps in these sections:

■Powering On the Switch

■Verifying Boot Fast

■Disconnecting Power

Powering On the Switch

To apply power to a switch that is directly connected to a DC power source, locate the circuit breaker on the panel board that services the DC circuit, and switch the circuit breaker to the ON position.

Verifying Boot Fast

When you power on the switch, it automatically begins a boot fast sequence. The System LED blinks green as the Cisco IOS software image loads. If the boot fast sequence fails, the System LED turns red.

Note: Boot fast failures are usually fatal. Call Cisco TAC immediately if your switch does not complete boot fast successfully.

Note: You can disable boot fast and run POST by using the Cisco IOS CLI. See the Cisco Connected Grid Switches System Management Software Configuration Guide and the Cisco IOS Master Command List, All Releases for more information.

Disconnecting Power

To disconnect power after successfully running boot fast:

1. Turn off power to the switch.

2. Disconnect the cables.

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.

Warning: Explosion Hazard—Do not connect or disconnect wiring while the field-side power is on; an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or that the area is nonhazardous before proceeding. Statement 1081

Caution: The input voltage source of the alarm output relay circuit must be an isolated source and limited to less than or equal to 24 VDC, 1.0 A or 48 VDC, 0.5 A.

Note: Wire connections to the alarm connector must be 16- to 20-AWG, UL- and CSA-rated, style 1007 or 1569 twisted-pair copper appliance wiring material (AWM) wire.

To wire the switch to an external alarm device:

1. Remove the captive screws that hold the alarm connector on the switch, and remove the connector from the switch chassis. See Figure 36.

Figure 36 Removing the Alarm Connector

2. Measure two strands of twisted-pair wire (16-to-20 AWG) long enough to connect to the external alarm device.

Choose between setting up an external alarm input or output circuit.

3. Use a wire stripper to remove the casing from both ends of each wire to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm).

Note: Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than the recommended amount of wire can leave exposed wire from the alarm connector after installation.

4. Insert the exposed wires for the external alarm device into the connections based on an alarm input or output circuit setup (see Table 13).

For example, to wire an alarm input circuit, complete the IN1 and REF connections (see Figure 37).

Figure 37 Inserting Wires into the Alarm Connector (Alarm Input Circuit)

5. Use a ratcheting torque flathead screwdriver to tighten the alarm connector captive screw (above the installed wire leads) to 2 in-lb (0.23 N-m) torque. See Figure 38 for details.

Note: Do not over-torque the captive screws of the alarm connectors. Do not exceed 2 in-lb (0.23 N-m) torque.

Figure 38 Torquing the Alarm Connector Captive Screws

6. Repeat the above steps to insert the input and output wires of one additional external alarm device into the alarm connector.

Figure 39 shows the completed wiring for two external alarm devices. The first alarm device circuit is wired as an alarm input circuit; the IN1 and REF connections complete the circuit. The second alarm device circuit is wired as an alarm output circuit that works on a normally open contact basis; the NO and COM connections complete the circuit.

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 40.

Figure 40 Connecting the Alarm Connector to the Switch

2. Use a ratcheting torque flathead screwdriver to tighten the alarm connector captive screw (above the installed wire leads) to 2 in-lb (0.23 N-m) torque. See Figure 38 for details.

Note: Do not over-torque the captive screws of the alarm connectors. Do not exceed 2 in-lb (0.23 N-m) torque.

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.

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 PoE-capable IE 2000U-16TC-GP model provides up to four ports of either PoE (15.4 W per port; IEEE 802.3af) or PoE+ (30 W per port; IEEE 802.3at). In order to utilize the PoE capability, you must attach a site source DC or power supply module to the PoE power connector on the switch faceplate. For more information about the PoE power connector, see Connecting Power to the Switch PoE DC-Input (Optional).

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

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

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

1. When connecting to workstations, servers, and routers, connect a straight-through cable to an RJ-45 connector on the front panel. See Figure 41.

When connecting to 1000BASE-T-compatible devices, use a twisted four-pair, Category 5 or higher grade cable.

The auto-MDIX feature is enabled by default. For configuration information for this feature, see the Cisco Connected Grid Switches Interfaces Software Configuration Guide or go to the Cisco IOS 15.2M&T command references, at:
http://www.cisco.com/en/US/products/ps11746/prod_command_reference_list.html

Figure 41 Connecting to an Ethernet Port

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

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

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:

–Check that the device at the other end is turned on.

–Check the cable and adapter. There might be a cable problem or a problem with the adapter installed on the attached device. See Troubleshooting for solutions to cabling problems.

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. These field-replaceable modules provide the optical interfaces, send (TX) and receive (RX).

You can use any combination of rugged SFP modules. See the Release Notes for the Cisco IE 2000U Switches at www.cisco.com/go/ie2000u-docs for the 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 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).

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

Installing SFP Modules into SFP Module Slots

Figure 42 shows an SFP module that has a bale-clasp latch.

Caution: Do not install or remove the SFP module with fiber-optic cables attached to it 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 42 SFP Module with a Bale-Clasp Latch

Installing Fiber-Optic SFP Modules

To insert a fiber-optic 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 you feel the connector on the module snap into place in the rear of the slot (Figure 43).

Figure 43 Installing an SFP Module into an SFP Module Slot

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 44, 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.

Figure 44 1000BASE-T SFP Transceiver

Caution: To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair, CAT5 cabling.

Note: 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. Figure 45, left view, shows the SFP installed in a latch-up orientation where the bale-clasp latching mechanism pivots up to the closed (locked) position. Figure 45, right view shows the SFP installed in a latch-down orientation where the bale-clasp latching mechanism pivots down to the closed (locked) position. Verify that you have the SFP transceiver oriented correctly when you position it in front of the port socket.

Figure 45 SFP Transceiver Socket Orientation

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 43).

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 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 46.

Figure 46 Opening a Bale-Clasp Latch on an SFP Module Using a Flat-Blade Screwdriver

5. Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.

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

Connecting to SFP Modules

This section describes how to connect to a fiber-optic SFP port. To connect to an RJ-45 Gigabit Ethernet port instead of a fiber-optic port, see the Connecting to a Dual-Purpose Port.

For instructions on how to install or remove an SFP module, see the Installing and Removing SFP Modules.

Warning: Class 1 laser product. Statement 1008

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

Caution: 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 guidelines in the Preparing for Installation. See Cable and Connectors for information about the LC on the SFP module.

To connect a fiber-optic cable to an SFP module:

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

2. Insert one end of the fiber-optic cable into the SFP module port. See Figure 47.

Figure 47 Connecting to a Fiber-Optic SFP Module Port

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

4. Observe the port status LED:

–Green indicates that the switch and the target device established a link.

–Amber indicates that the STP is discovering the network topology and is searching for loops. This process takes about 30 seconds, and then the port 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. See Troubleshooting for solutions to cabling problems.

5. If necessary, reconfigure and restart the switch or the target device.

Connecting to a Dual-Purpose Port

The dual-purpose port is a single port with two interfaces, one for an RJ-45 cable and another for an SFP module. Only one interface can be active at a time. If both interfaces are connected, the SFP module has priority. For more information about dual-purpose ports, see the Power Connectors.

Warning: Class 1 laser product. Statement 1008

Caution: 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 guidelines in the Preparing for Installation. See Cable and Connectors for information about the LC on the SFP module.

To connect to a dual-purpose port:

1. Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot, and connect a cable to the SFP module port. See Figure 48.

For more information about RJ-45 connections, SFP modules, and optical connections, see the Connecting to 10/100 and 10/100/1000 Ports, the Installing and Removing SFP Modules, and the Connecting to SFP Modules.

Figure 48 Connecting to a Dual-Purpose Port

2. Connect the other end of the cable to the other device.

By default, the switch detects whether an RJ-45 connector or SFP module is connected to 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 typ e interface configuration command.
