OVERVIEW

The ECS3510-28F is an intelligent Layer 2 switch designed for delivering Fiber­To-The-Home (FTTH) for high-speed Internet access. Deployed at the service
provider’s central office (CO), the switch supports up to 24 subscribers through
100BASE-FX single-fiber downlink connections to remote CPEs (customer
premises equipment). Uplink connections from the switch to other devices at the
CO are provided by four Gigabit combination ports, which are comprised of four
RJ-45 ports and four SFP transceiver slots.

The switch includes an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access for managing the
switch. The switch also supports comprehensive OAM (Operations,
Administration, and Maintenance) functions for management of CPEs on the
subscriber fiber links.

| Introduction

SWITCH ARCHITECTURE

The 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 a straight-through UTP or STP Ethernet cable
and the included RJ-45-to-DB-9 converter.

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

DESCRIPTION OF HARDWARE

100BASE-FX FIBER PORTS

The switch provides 24 SC ports on the front of the switch. Each single-fiber SC
connector supports a 100BASE-FX full-duplex link to a subscriber’s CPE. The
switch’s fiber transceivers use Wavelength Division Multiplexing (WDM)
technology to achieve bi-directional operation (1550 nm transmit, 1310 nm
receive) over a single optical fiber. The WDM single-mode fiber links can run up
to 15 km.

The 100 Mbps bandwidth of the fiber links can be restricted by rate-limiting,
which is configurable thorugh switch management. Each port also supports

HAPTER

| Introduction

Description of Hardware

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

RJ-45 PORTS

The switch contains four 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 25~28. 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 53)

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 switch contains four Small Form Factor Pluggable (SFP) transceiver slots
that operate at 1000 Mbps full duplex. These slots support 1000 Mbps SFP
Gigabit Ethernet transceivers. The supported transceiver types are listed below:

◆ SFP 100BX20

◆ SFP 100BX20D

◆ SFP 1000SX

◆ SFP 1000LX

◆ SFP 1000LHX

◆ SFP 1000ZX

CONSOLE PORT

An RJ-45 serial console port is provided on the switch front panel for a
connection to a console device through a straight-through UTP or STP Ethernet
cable and an RJ-45-to-DB-9 converter. The console device can be a PC or
workstation running a VT-100 terminal emulator, or a VT-100 terminal.
An RJ-45-to-DB-9 converter is supplied with the unit for connecting to the
console port.

2 NETWORK PLANNING

FIBER-TO-THE-HOME (FTTH)

Fiber-To-The-Home (FTTH) has always been an attractive option for Internet
access. It has all the benefits of optical fiber. It provides a future-proof network,
in that you do not have to go through the hassles of upgrading from ADSL to
XDSL, or digital co-ax to digital wireless. It does not have to struggle with
electromagnetic interference problems, and with no active “outside-plant”
components, it offers the highest reliability. Moreover, it does not require electric
power and is immune to lightning and other transients. These properties of fiber
lead to the lowest possible power and operational costs, such as maintenance,
provisioning and facilities planning.

The ECS3510-28F and CPE provide an ideal FTTH system, allowing a service
provider to extend an Ethernet connection over optical fiber directly to a
subscriber. The ECS3510-28F contains 24 100BASE-FX full-duplex single-fiber
single-mode cable connections that run from the service provider’s central office
(CO) directly to CPEs installed at subscriber premises. Each single-mode fiber
connection can be run up to a distance of 15 km from the CO. The switch also
provides four 1000BASE-T/SFP uplink ports for connections to other switches or
routers at the CO.

The CPE is typically a single-channel fiber-to-copper converter housed in a
compact unit. The CPE connects to the fiber cable from the CO and provides one
standard 10/100BASE-TX RJ-45 Ethernet port for connecting to a subscriber’s
PC, switch, or other network device using twisted-pair cable.

APPLICATION EXAMPLES

The ECS3510-28F switch is designed to offer a cost-effective solution for FTTH,
providing downlink fiber connections to subscribers and high-bandwidth twisted­pair uplink connections to core switches and routers at the CO.

Some basic connection configurations are described in the following pages.

DOWNLINK FIBER CONNECTIONS

Fiber optic technology allows for longer cabling than any other media type. A
100BASE-FX single-mode fiber link from the chassis can connect to a subscriber
up to 15 km away. The CPE is installed inside a subscriber’s premises, so there
are no active outside components between the CO and the end user.

The figure below illustrates a basic switch to CPE connection.

UPLINK SFP CONNECTIONS

The ECS3510-28F switch provides 24 downlink fiber ports and four combination
SFP/RJ-45 uplink ports. The 1000BASE-T ports can provide a trunked high­bandwidth connection to a core switch or router at the CO. Besides balancing the
load across each port in the trunk, the additional port provides redundancy by
taking over the load if the other port in the trunk 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. 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-LH: 80 km (49.7 miles) for single-mode fiber.

■

1000BASE-LHX: 40 km (24.8 miles) for single-mode fiber.

■

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

■

1000BASE-BX20: 20 km (12.4 miles) for single-mode fiber.

■

1000BASE-BX10: 10 km (6.2 miles) for single-mode fiber.

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

4 MAKING NETWORK CONNECTIONS

The ECS3510-28F switch is designed to provide high-speed Internet access to
individual subscribers through its 100BASE-FX single-fiber downlink
connections. Four combination 1000BASE-T/SFP ports provide the uplink
connection from the switch to other switches or routers at the central office.

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.

C

AUTION

:

Do not plug a phone jack connector into an RJ-45 port. This
will damage the switch. Use only twisted-pair cables with RJ-45
connectors that conform to FCC standards.

Fiber Optic Devices

FIBER OPTIC DEVICES

Each single-fiber SC connector on the switch’s front panel connects directly to a
CPE at the subscriber’s premises.

The switch’s single-fiber ports require one strand of 9/125 micron single-mode
fiber optic cable with an SC connector at the switch end.

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, 1000BASE­LH, 1000BASE-LHX, 1000BASE-ZX, 1000BASE-BX20, or 1000BASE-BX10) can
be used for uplink connections from the switch to other network devices at the
CO. A Gigabit SFP transceiver may also be used for long distance connections to
devices at another service provider site.

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.

W

ARNING

:

This switch uses 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.

W

ARNING

:

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.

When selecting a fiber SFP device, considering safety, please

1. Remove and keep the SC/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.

Connectivity Rules

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 100BASE-FX fiber optic ports operate at 100 Mbps, full duplex. You can run
each single-mode fiber link up to a maximum of 15 kilometers from the central
office. However, note that power budget constraints must also be considered
when calculating the maximum cable length for each specific connection.

The SFP fiber optic ports operate at 1 Gbps, full duplex, with auto-negotiation of
flow control. The maximum length for fiber optic cable operating at Gigabit
speed will depend on the fiber type as listed under "1000 Mbps Gigabit Ethernet

Collision Domain" on page 47.

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

| Making Network Connections

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.

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.

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.
