Switch Architecture

This switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.

Network Management Options

This switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a management agent that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications. To manage the switch, you can make a direct connection to the console port (out-of-band), or you can manage the switches through a network

connection (in-band) using Telnet, the on-board web agent, or SNMP-based network management software.

The management port (RJ-45) provides a dedicated management channel that operates outside of the data transport network. This makes it possible to re-configure or troubleshoot the switch over either a local or remote connection to the management port when access via the data channel is not possible or deemed insecure.

For a detailed description of the switch’s advanced features, refer to the SMC7824M/ESW Management Guide.

Description of Hardware

100BASE-TX and 1000BASE-T Ports

The switch contains 24 100BASE-TX RJ-45 ports that operate at 10/100 Mbps, half or full duplex, and two 1000BASE-T RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all of the RJ-45 ports support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. (See “1000BASE-T Pin Assignments” on page B-5.)

Each of these ports support auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10, 100 or 1000 Mbps) can be selected automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually.

Each port also supports auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated.

100BASE-TX Management Port

The 10/100BASE-TX port labeled “Mgmt” provides a dedicated management interface which is segregated from the data traffic crossing the other ports.

1-3

BOUT THE TIGERACCESSSWITCH

This port supports auto-negotiation, so the optimum transmission mode (half or full duplex) and data rate (10 or 100 Mbps) can be selected automatically, if this feature is also supported by the attached device. However, note that the interface connection parameters of this port cannot be configured.

Console Port

The console port on the switch’s front panel is an RJ-45 connection using a male DB-9 connector that enables a connection to a terminal for performing switch monitoring and configuration functions. The terminal may be a PC or workstation running terminal emulation software, or a terminal configured as a Data Terminal Equipment (DTE) connection. A null-modem wired serial cable is supplied with the switch for connecting to this interface.

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with RJ-45 ports (ports 25~26 on the front panel or ports 27~28 on the optional modules). In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used. The switch can also be configured to force the use of an RJ-45 port or SFP slot, as required.

Alarm Interface Port

The DB-15 alarm port on the switch’s front panel can be used to provide alarm, service port, and BITS clock reference interfaces. The switch supports two sets of alarm relay contacts (major and minor), and 4 external customer site alarm inputs. It also provides an alarm cutoff button (labeled ACO). Refer to “Connecting to the Alarm Port” on page 3-15 for a description of the pin assignments used to connect to the alarm port.

Port and System Status LEDs

This switch includes a display panel for key system and port indications that simplifies installation and network troubleshooting. The LEDs, which are located on the front panel and the power module trays for easy viewing, are shown below and described in the following tables.

If an SFP transceiver (purchased separately) is installed in a slot and has a valid link, the associated RJ-45 port is disabled and cannot be used. The switch can also be configured to force the use of an RJ-45 port or SFP slot, as required.

When connecting to the 1000BASE-T RJ-45 port, Category 5, 5e, or 6 twisted-pair cable can be used to connect to another device up to 100 m (328 ft) away. The 1000BASE-T port operates at 10, 100, and 1000 Mbps. At 1000 Mbps it operates at full duplex and supports auto-negotiation of flow control. At 10/100 Mbps it supports auto-negotiation of speed, duplex mode (i.e., half or full duplex), and flow control. Note that you should first test the cable installation for IEEE 802.3ab compliance. See “1000BASE-T Cable Requirements” on page 4-6.

This module also provides an SFP slot that supports 1000BASE-SX, 1000BASE-LX and 1000BASE-ZX transceivers. For a full listing of the supported transceivers, see “Ordering Information” on page E-1.

Introduction to Switching

A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.

When performance bottlenecks are caused by congestion at the network access point (such as the network card for a high-volume file server), the device experiencing congestion (server, power user or hub) can be attached directly to a switched port. And, by using full-duplex mode, the bandwidth of the dedicated segment can be doubled to maximize throughput.

When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.

A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly boost bandwidth while using conventional cabling and network cards.

Application Examples

This switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below.

ETWORK PLANNING

Collapsed Backbone

This switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future. In a basic stand-alone configuration, it can provide direct full-duplex connections for up to 28 workstations or servers. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers. When the time comes for further expansion, just connect to another hub or switch using one of the Gigabit Ethernet ports built into the front panel, or a Gigabit Ethernet port on a plug-in SFP transceiver.

In the figure below, the switch is operating as a collapsed backbone for a small LAN. It is providing dedicated 100 Mbps full-duplex connections to workstations, and 1 Gbps full-duplex connections to servers

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-ZX link up to 70 km. This allows a switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

A 1000BASE-SX SFP transceiver can be used for a high-speed connection between floors in the same building. For long-haul connections, a 1000BASE-ZX SFP transceiver can be used to reach another site up to 70 kilometers away.

The figure below illustrates three switches interconnecting multiple segments with fiber cable.

Making VLAN Connections

These switches support VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.

VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs. Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger networks, and all the VLANs assigned to the inter-switch links.

These switches also support multiple spanning trees which allow VLAN groups to maintain a more stable path between all VLAN members. This can reduce the overall amount of protocol traffic crossing the network, and provide a shorter reconfiguration time if any link in the spanning tree fails.

Application Notes

1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode.

2. To interconnect distinct VLANs or IP subnets, you can attach the

switch to a standard Layer 3 router. For network applications that require routing between dissimilar network types, attach the switch to a multi-protocol router.

3. As a general rule, the length of fiber optic cable for a single switched

link should not exceed:

• 1000BASE-SX: 550 m (1805 ft) for multimode fiber, duplex fiber

• 1000BASE-LX: 10 km (6.2 miles) for single-mode fiber, duplex fiber

• 1000BASE-ZX: 70 km (43 miles) for single-mode fiber, duplex fiber

However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.

2. SFP transceivers are not provided in the switch package.

Grounding the Chassis

Before powering on the switch, ground the switch to earth as described below.

1. Ensure that the rack on which the switch is to be mounted is properly

grounded and in compliance with ETSI ETS 300 253.

2. Ensure that there is a good electrical connection to the grounding

point on the rack (no paint or isolating surface treatment).

3. Disconnect all power cables to the switch.

4. The switch chassis is connected internaly to 0 V. This circuit is

connected to the single-hole grounding terminal on the back of the switch. The surface area around this terminal is not painted in order to provide for a good connection. Attach a 6 AWG stranded copper wire to the grounding terminal on the switch.

5. Then attach the grounding wire to the ground point on the rack.

Caution: The earth connection must not be removed unless all supply

connections have been disconnected.

3-9

NSTALLING THE SWITCH

Connecting to a Power Source

This switch supports both AC and DC power conversion modules.

Connecting DC Power

When a -48 VDC power conversion module is installed in the switch, an external DC power supply must be connected to the DC power connection on the left side of the front panel.

Warning: Before wiring the DC plug or connecting power to the switch,

ensure that power to the feed lines is turned off at the supply circuit breaker or disconnected from the power bus.

Notes: 1. To provide adequate circuit protection between the DC

power supply and the switch, all intermediate wiring and circuitry should be rated to carry a load at least two times the maximum rating for this switch (see “Power Supply” on page C-2).

2. The wiring between the DC power supply and the switch must be stranded copper wire within the range of 10 to 24 AWG.

3. Wiring for the power input terminals on the switch are described below. Wiring of the DC power supply terminals depends on the equipment in use on the local site, but should be wired in such a way as to meet the input requirements shown in Figure 3-7 “DC Plug Connections” on page 3-12. The wiring should also be color coded according to local standards to ensure that the input power and ground lines can be easily distinguished.

3-10

4. When using two power conversion modules with the switch, either AC or DC modules can be used – both AC, both DC, or one AC and one DC.

ONNECTING TO A POWER SOURCE

To connect the switch to a power source:

1. First verify that the external DC power supply can provide -36 to

-72 VDC, 4 A minimum for the -48 VDC power conversion module.

2. Prepare two wires for each power source to be used (A or B). Use 10 to 24 AWG stranded copper wire. Make sure these wires are not plugged into the power source.

3. Use a wire stripper to carefully strip about a half an inch of the outer insulation off the end of each wire, exposing the copper core.

4. Twist the copper wire strands together to form a tight braid. If possible, solder the exposed braid of wire together for better conductivity.

5. Connect the external power feed and power ground/return lines to the DC plug (provided with the switch) as shown below. The power leads are labeled on the front of the chassis, above the DC power connection block. The -48 VDC power feed uses the “-48VDC” input and RETA/B (Return) lines for power source A and B respectively, while +24 VDC power feed uses the indicated “24VDC” input and

GNDA/B (Ground) lines for power source A and B respectively

. Use a small flat-tip screwdriver to loosen the screws on the power plug and open the wire clamps.

6. Insert the wire leads into the openings shown in the figure below. Each lead inserted in the power plug must match the lead attached to the power source. Use the label above the DC power connection block to identify the appropriate power input and return or ground lines.

Warning: If the power leads are plugged into the wrong holes, the power

supply will not work properly and may damage the switch.

The 24 VDC power conversion module is not currently supported for this switch.

7. Push each wire about half an inch into the opening on the plug, and tighten down the clamp screw securely. You should not be able to pull on the wire and dislodge it.

8. Insert the power plug in the power receptacle on the left side of the front panel.

9. At the power source, turn on the power for the feed lines or power bus.

10. After the power source is tuned on, set the power button on the front of the power conversion module to the ON position (marked “–”).

11. Check the indicators on the power conversion module as the switch is powered on to verify that the -48V LED indicating external power status is on, and that the +12V LED indicating internal power conversion is on. If not, recheck the power supply and power cable connections at the supply source and at power conversion module.

12. If you have installed both a primary and redundant power conversion module, verify that the LEDs on both modules are lit as indicated in the preceding step.

3-12

ONNECTING TO A POWER SOURCE

Connecting AC Power

When a universal AC power module is installed in the switch, external AC power must be supplied to the module.

To connect the switch to a power source:

1. First verify that the external AC power supply can provide 100 to 240 VAC, 50-60 Hz, 2 A minimum.

2. Plug the power cable into a grounded, 3-pin, AC power source.

Note: For international use, you may need to change the AC line

cord. You must use a line cord set that has been approved for the receptacle type in your country.

3. Insert the plug on the other end of the power cable directly into the receptacle on the AC power module.

Figure 3-8 AC Power Receptacle

4. Check the indicators on the power module as the switch is powered on to verify that the AC LED indicating external power status is on, and that the +12V LED indicating internal power conversion is on. If not, recheck the power supply and power cable connections at the supply source and at power module.

Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-ZX) can be used for a backbone connection between switches, or for connecting to a high-speed server.

Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends. 1000BASE-SX/LX/ZX uses duplex fiber, operating at the same wavelength for both the transmit and receive signals (SX: 850 nm, LX: 1310 nm, ZX: 1550 nm).

Warning: These switches use lasers to transmit signals over fiber optic

cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

Note: When selecting a fiber SFP device, considering safety, please

make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1 SFP transceiver.

Hinweis: Bei der Wahl eines Glasfasertransceivers muß für die

Beurteilung der Gesamtsicherheit beachtet werden, das die maximale Umgebungstemperatur des Transceivers für den Betrieb nicht niedriger ist als die für dieses Produkts. Der Glasfasertransceiver muß auch ein überprüftes Gerät der Laser Klasse 1 sein.

1. Remove and keep the LC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables

will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Figure 4-3 Making Connections to SFP Transceivers

4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.

The 1000BASE-SX/LX/ZX fiber optic ports operate at 1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit speeds will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet Cable Lengths” on page 4-6. Also, remember to consider power budget constraints when calculating the maximum cable length for each specific connection.

AKING NETWORK CONNECTIONS

Connectivity Rules

When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

1000BASE-T Cable Requirements

All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e specification includes test parameters that are only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running 1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3-2005 standards.

Cable Labeling and Connection Records

When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption.

To best manage the physical implementations of your network, follow these guidelines:

• Clearly label the opposing ends of each cable.

• Using your building’s floor plans, draw a map of the location of all network-connected equipment. For each piece of equipment, identify the devices to which it is connected.

• Note the length of each cable and the maximum cable length supported by the switch ports.

• For ease of understanding, use a location-based key when assigning prefixes to your cable labeling.

• Use sequential numbers for cables that originate from the same equipment.

• Differentiate between racks by naming accordingly.

• Label each separate piece of equipment.

• Display a copy of your equipment map, including keys to all abbreviations at each equipment rack.

OWER AND COOLING PROBLEMS

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has not been disabled. If it has not been disabled, then check the network cabling that runs between your remote location and the switch.

Note: The management agent can accept up to four simultaneous Telnet

sessions. If the maximum number of sessions already exists, an additional Telnet connection will not be able to log into the system.

Twisted-Pair Cable and Pin Assignments

For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: DO NOT plug a phone jack connector into any RJ-45 port.

Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Caution: Each wire pair must be attached to the RJ-45 connectors in a

specific orientation as shown on the following pages.

The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

WISTED-PAIR CABLE AND PIN ASSIGNMENTS

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on these switches, you can use either straight-through or crossover cable to connect to any device type.)

You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet connections.

1000BASE-T Pin Assignments

All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.

Use 100-ohm Category 5, 5e or 6 unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for 1000BASE-T connections. Also be

that the length of any twisted-pair connection does not exceed 100

sure meters (328 feet)

1000BASE-T Cable Requirements

Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch cables between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem:

1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables.

2. Reduce the number of connectors used in the link.

3. Reconnect some of the connectors in the link.

IBER STANDARDS

Fiber Standards

The current TIA (Telecommunications Industry Association) 568-A specification on optical fiber cabling consists of one recognized cable type for horizontal subsystems and two cable types for backbone subsystems.

Horizontal 62.5/125 micron multimode (two fibers per outlet). Backbone 62.5/125 micron multimode or single mode.

TIA 568-B will allow the use of 50/125 micron multimode optical fiber in both the horizontal and backbone in addition to the types listed above. All optical fiber components and installation practices must meet applicable building and safety codes.

• Sicherstellen, dass das verdrehte Kabel stets weg von anderen Stromkabeln, Neonleuchteinrihtungen und anderen Quellen von moglichen elektrischen Storungen verlegt wird, wie z. B. von Radios und Transmittern.

D-1

ERMAN INSTRUCTIONS

• Sicherstellen, dass das Gerat an eine separate Stromquelle mit Erdanschlus mit einer Netzspannung von 100 bis 240 V AC (Wechselstromspannung), 50 bis 60 Hz, und innerhalb in einem Abstand von 2,44 m (8 Fus) zu jedem Gerat installiert wird und on einem separaten Trennschalter bzw. Leistungsschalter mit Strom versorgt wird. Fur alle Gerate wird empfohlen, einen Filter oder einen Überspannungsschutz zu verwenden.

Montage (Rack Mounting Instructions)

Switch-Einheiten können an ein standardmäßiges 19-Zoll Einrichtungsrack, einen Arbeitstisch oder ein Regal montiert werden. Folgend finden Sie die Montageanweisungen für jeden Positionstyp.

Rack-Montage

Beachten Sie die folgenden Faktoren, bevor Sie die Rack-Montage beginnen:

• Temperatur: Da die Temperatur innerhalb einer Rackeinheit höher als die Raumumgebungstemperatur sein kann, stellen Sie bitte sicher, dass die Rackumgebungstemperatur innerhalb des angegebenen Betriebstemperaturbereichs liegt. (Siehe “Temperatur” auf Seite C-2.)

• Mechanische Last: Stellen Sie kein Gerät auf eine Rack-Montageeinheit.

• Stromüberlastung: Stellen Sie sicher, dass der Netzkreis der Rackeinheit nicht überlastet wird.

• Erdung: Die Rack-Montageeinheit muss richtig geerdet werden. Besondere Acht sollten Sie bei Verbindungen geben, die nicht direkt zum Netz führen.

D-2

DAS E

RDEN DES GEHÄUSES

So montieren Sie Geräte an ein Rack:

1. Befestigen Sie die Metallwinkel mit den im Metallwinkel-Montageset erhältlichen Schrauben an dem Gerät.

2. Befestigen Sie das Gerät mit vier Rackmontageschrauben (nicht beigelegt) an dem Rack.

3. Wenn Sie nur einen Switch installieren, dann springen Sie bitte über zu “Verbinden mit einer Stromquelle” auf Seite 3-9 am Ende dieses Kapitels.

4. Wenn Sie mehrere Switches installieren möchten, dann montieren Sie sie untereinander in einer beliebigen Reihenfolge.

ROUNDING THE CHASSIS

Das Erden des Gehäuses

(Grounding the Chassis)

Bevor Sie den Switch anschalten, erden Sie den Switch mit dem Erdboden, wie im Folgenden beschrieben.

)

1. Vergewissern Sie sich, dass das Rack, auf welchem der Switch montiert werden soll, regelrecht geerdet ist und ETSI ETS 300 253 genügt.

2. Vergewissern Sie sich, dass eine gute elektrische Verbindung zum Erdungspunkt des Racks besteht (keine Farbe oder isolierende Oberflächenbehandlung).

3. Entfernen Sie alle Stromkabel vom Switch.

4. Das Switchgehäuse ist intern an 0 V angeschlossen. Der Schaltkreis ist mit dem Einzelloch-Erdungspunkt auf der Rückseite des Switches verbunden. Die Oberfläche um diesen Punkt ist nicht bemalt, um eine gute Verbindung zu gewährleisten. Schließen Sie einen 6 AWG verdrillten Kupferdraht an den Erdungspunkt des Switches an.

D-3

ERMAN INSTRUCTIONS

5. Dann schließen Sie das Erdungskabel an den Erdungspunkt des Racks an.

Vorsicht: Die Erdungsverbindungen dürfen nicht entfernt werden, es sei

denn, alle Verbindungen zu den Stromquellen sind abgezogen.

Anschluss an eine Stromquelle

(Connecting to a Power Source)

Dieser Switch unterstützt sowohl Gleichstrom- als auch Wechselstrom-Umwandlungsmodule.

Anschluss an Gleichstrom

Wenn ein-48 VDC Stromwandlungsmodul im Switch installiert ist, muß eine externe Gleichstromquelle an den Gleichstromanschluss auf der linken Seite der Vorderfront angeschlossen werden

Warnung: Vor dem Anschließen des DC Steckers oder Anschluß des

Geräts ans Versorgungsnetz sicherstellen, daß die Stromversorgung ausgeschaltet ist oder keine Verbindung dazu besteht.

Bemerkung: 1. Um einen ausreichenden Schaltkreisschutz zwischen

der Gleichstromquelle und dem Switch zu bieten, sollten alle Drähte und Schaltungen mindestens das zweifache der maximalen Ladung dieses Switches führen können (Siehe ““Power Supply”” auf Seite C-2).

2. Die Drähte zwischen der Gleichstromquelle und dem Switch sollen aus gedrilltem Kupfer bestehen und im Bereich von 10 bis 24 AWG liegen.

3. Die Verdrahtung der Stromeingangspunkte des Switches ist unten beschrieben. Die Verdrahtung der Gleichstromquellenpunkte hängen vom Einsatzort ab, sollten aber so angelegt sein, dass die Eingangsanforderungen, wie sie in Figure 3-7 “DC

D-4

NSCHLUSS AN EINE STROMQUELLE

Plug Connections” auf Seite 3-8 beschrieben sind, erfüllt sind. Die Drähte sollten auch gemäß der örtlichen Normen gefärbt sein, um sicherzustellen, dass die Stromeingangskabel und die Erdungsdrähte leicht unterschieden werden können.

4. Wenn Sie die zwei Stromwandlungsmodule benutzen, können Sie sowohl Wechsel- als auch Gleichstrommodule verwenden – beide Wechstelstrom, beide Gleichstrom oder ein Wechselstrom und ein Gleichstrom. Die einzige Einschränkung besteht darin, dass, wenn Sie zwei Gleichstromwandulungsmodule benutzen, beide Module vom gleichen Typ sein müssen, z.B. beide -48 V Gleichstrom.

So schließen Sie den Switch an eine Stromquelle an:

1. Stellen Sie zunächst sicher, dass die externe Gleichstromquelle -36 bis

-72 V Gleichstrom, mit mindestens 4 A für das -48 V Gleichstrom Stromwandlungsmodul liefern kann.

2. Halten Sie zwei Drähte für jede Stromquelle, die benutzt wird, bereit (A oder B). Benutzen Sie 10 bis 24 AWG verdrillte Kupferdrähte. Vergewissern Sie sich, dass diese Drähte nicht in die Stromquelle gesteckt werden.

ONNECTING TO A POWER SOURCE

)

3. Entfernen Sie mit einer Abstreifzange etwa 2 cm von der Isolierung am Ende des Drahtes, um den Kupferkern freizulegen.

4. Verdrehen Sie die Kupferstränge, um eine feste Litze zu erhalten. Wenn es möglich ist, verlöten Sie die freigelegten Litzen des Drahtes, um eine bessere Leitfähigkeit zu erreichen.

5. Verbinden Sie die externen Stromleitungen und Erdungsdrähte mit dem Gleichstromstecker (mit dem Switch mitgeliefert) wie unten gezeigt. Die Netzanschlusskabel sind auf der Vorderseite des Gehäuses, über dem Gleichstromblock, gekennzeichnet. Die -48 V Gleichstromzuleitung benutzt den “-48VDC” Eingang und die

Wenn nicht, überprüfen Sie noch einmal die Stromquelle und die Stromverbindungen an der Stromquelle und am Stromwandlungsmodul.

12. Wenn Sie sowohl ein primäres als auch ein freigesetztes Stromwandlungsmodul installiert haben, vergewissern Sie sich, dass die LEDs beider Module so leuchten, wie in den vorherigen Schritten angegeben.

ONNECTING TO A POWER SOURCE

Wechselstromanschluss

Wenn ein universelles Wechselstrommodul im Switch installiert ist, muß dem Modul externer Wechselstrom zugeführt werden.

So schließen Sie den Switch an eine Stromquelle an:

)

1. Vergewissern Sie sich zunächst, dass die externe Wechselstromquelle 100 bis 240 V Wechselstrom, 50-60 Hz, mit mindestens 2 A liefern kann.

2. Stecken Sie den Stromkabel in eine geerdete, 3-Pin Wechselstromquelle.

Bemerkung: Für den internationalen Gebrauch kann es sein, dass Sie

das Wechselstromkabel austauschen müssen. Sie müssen ein Kabel benutzen, das für die Anschlusstypen in Ihrem Land genehmigt ist.

3. Stecken Sie den Stecker am anderen Ende des Stromkables direkt in die Anschlussbuchse des Wechselstrommoduls.
