SWITCH ARCHITECTURE

This Gigabit Ethernet 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.

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

With a comprehensive array of LEDs, the switch provides “at a glance”
monitoring of network and port status. The switch can be managed over the
network with a web browser or Telnet application, or via a direct connection to
the console port. The switch includes a built-in network management agent that
allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9)
protocols. It also has an RJ-45 serial port on the front panel for out-of-band
management. A PC may be connected to this port for configuration and
monitoring out-of-band through the included RJ-45-to-DB-9 console cable.

For a detailed description of the management features, refer to the Management
Guide.

DESCRIPTION OF HARDWARE

RJ-45 PORTS

The switch contains two combination RJ-45 ports that operate at 10 Mbps or
100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. They are shared with
SFP ports 23~24. 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.

Because 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 “Twisted-Pair Cable and Pin Assignments” on page 59)

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.

SFP+ TRANSCEIVER SLOTS

The Small Form Factor Pluggable Plus (SFP+) transceiver slots are 10G capable
slots that support both SFP and SFP+ transceivers (purchased seperately).

CONSOLE PORT

An RJ-45 serial console port is provided on the switch front panel for a
connection to a console device through an included console cable. The console
device can be a PC or workstation running a VT-100 terminal emulator, or a VT­100 terminal.

2 NETWORK PLANNING

INTRODUCTION TO SWITCHING

A network switch allows simultaneous transmission of multiple packets via non­crossbar switching. This means that it can partition a network more efficiently
than bridges or routers. The switch has, 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

The 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.

NETWORK AGGREGATION PLAN

With 28 parallel bridging ports (i.e., 28 distinct collision domains), the switch can
collapse a complex network down into a single efficient bridged node, increasing
overall bandwidth and throughput.

In the figure below, the 1000BASE-X SFP ports on the switch are providing 1000
Mbps connectivity for up to 24 segments. In addition, the switch is also
connecting several servers at 1000 Mbps.

Application Examples

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 100 km.
This allows the switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.

The figure below illustrates the switch connecting multiple segments with fiber
cable.

MAKING VLAN CONNECTIONS

This switch supports 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.

When connecting to a switch that does not support IEEE 802.1Q

VLAN tags, use untagged ports.

Application Notes

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. Avoid using flow control on a port connected to a hub unless it is actually

required to solve a problem. Otherwise back pressure jamming signals may
degrade overall performance for the segment attached to the hub.

3. Based on recommended standards, the length of fiber optic cable for a

single switched link should not exceed:

■

1000BASE-SX: 550 m (1805 ft) for multimode fiber.

■

1000BASE-LX: 10 km (6.2 miles) for single-mode fiber.

■

1000BASE-ZX: 100 km (62 miles) for single-mode fiber.

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

CONNECTING NETWORK DEVICES

The switch is designed to be connected remote devices using optional SFP
transceivers. It may also be connected to 10, 100, or 1000 Mbps network cards
in PCs and servers, as well as to other switches and hubs.

TWISTED-PAIR DEVICES

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45
connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T
connections, Category 5 or better for 100BASE-TX connections, and Category 3
or better for 10BASE-T connections.

CABLING GUIDELINES

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout
configuration, so you can use standard straight-through twisted-pair cables to
connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

FIBER OPTIC SFP DEVICES

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, 1000BASE­ZX) 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.

1. Remove and keep the LC port’s rubber plug. When not connected to a fiber

cable, the rubber plug 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 optic 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.

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 and 6 specifications include 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.

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. If you still
cannot isolate the problem, 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.

The management agent accepts 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.

B CABLES

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.

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.

10BASE-T/100BASE-TX PIN ASSIGNMENTS

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or
100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure

that

the length of any twisted-pair connection does not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit 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. In straight-through cable, pins 1, 2,
3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3,
and 6 at the other end of the cable. When using any RJ-45 port on this switch,
you can use either straight-through or crossover cable.

Note: The “+” and “-” signs represent the polarity of the wires that make

up each wire pair.

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 this switch, 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

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 sure

that the

length of any twisted-pair connection does not exceed 100 meters (328 feet)

.

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.

USER DATAGRAM PROTOCOL (UDP)

UDP provides a datagram mode for packet-switched communications. It uses IP

as the underlying transport mechanism to provide access to IP-like services.
UDP packets are delivered just like IP packets – connection-less datagrams that
may be discarded before reaching their targets. UDP is useful when TCP would
be too complex, too slow, or just unnecessary.

UTP

Unshielded twisted-pair cable.

VIRTUAL LAN (VLAN)

A Virtual LAN is a collection of network nodes that share the same collision
domain regardless of their physical location or connection point in the network.
A VLAN serves as a logical workgroup with no physical barriers, allowing users to
