10/100/1000Base-T Twisted Pair Ports
This section describes the twisted pair ports on the switches.
Connector TypeThe ports are 8-pin RJ-45 connectors that use four pins at 10 or 100 Mbps
and all eight pins at 1000 Mbps. For the pin assignments, refer to “RJ-45
Twisted Pair Port Pinouts” on page 67.
SpeedA port’s speed can be 10, 100, or 1000 Mbps. The speed can be set
automatically through Auto-Negotiation, the default setting, or manually
with the AlliedWare Plus
To operate at 1000 Mbps, a twisted pair port must be set to Auto Negotiation. The speed of a twisted pair port cannot be set manually
to 1000 Mbps.
TM
Operating System Software.
Duplex ModeA twisted pair port can operate in either half- or full-duplex mode. (Full-
duplex mode is the only mode available when a port is operating at 1000
Mbps.) The twisted pair ports are IEEE 802.3u-compliant and AutoNegotiate the duplex mode setting.
You can disable Auto-Negotiation on one or all of the switch ports so that
you can set the duplex mode manually through the AlliedWare Plus
Operating System Software.
In order for a switch port to successfully Auto-Negotiate its duplex
mode with a 10 or 100 Mbps end node, the end node must be
configured for Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur. A switch port using Auto-Negotiation defaults
to half-duplex if it detects that the end node is not using AutoNegotiation. This results in a mismatch if the end node is operating
at a fixed duplex mode of full-duplex.
To avoid this problem when connecting an end node with a fixed
duplex mode of full-duplex to a switch port, use the AlliedWare
TM
Plus
the port and set the port speed and duplex mode manually.
Operating System Software to disable Auto-Negotiation on
TM
Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).

Chapter 1: Overview
Cable TypeThe cabling requirements for a 10/100/1000Base-T port are:
For 10 Mbps operation: Standard TIA/EIA 568-B-compliant Category 3
or better shielded or unshielded cabling with 100 ohm impedance and
a frequency of 16 MHz.
For 100 Mbps operation: Standard TIA/EIA 568-A-compliant Category
5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded
or unshielded cabling with 100 ohm impedance and a frequency of 100
MHz.
For 1000 Mbps operation: Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
shielded or unshielded cabling with 100 ohm impedance and a
frequency of 100 MHz.
Auto-MDI/
MDI-X
The twisted pair ports on the switch are IEEE 802ab-compliant and feature
auto-MDI/MDI-X. This feature, available when a port’s speed and duplex
mode are set through Auto-Negotiation, automatically configures a switch
port to MDI or MDI-X depending on the wiring configuration of the port on
the end node. This allows you to connect any network device to a port on
the switch using a straight-through twisted pair cable.
If Auto-Negotiation is disabled on a port and the speed and duplex mode
are set manually, the auto-MDI/MDI-X feature is also disabled and the
port’s wiring configuration defaults to the MDI-X setting. This setting can
be configured with the AlliedWare Plus
TM
Operating System Software.
Port PinoutsRefer to Table 10 on page 67 for the port pinouts when a twisted pair port
operates at 10 or 100 Mbps in the MDI configuration and Table 11 on
page 67 for the MDI-X configuration. For port pinouts when a twisted pair
port operates at 1000 Mbps, refer to Table 12 on page 68.

SFP Transceiver Slots
Note
All of the x600 Series switches feature slots for four optional Gigabit
Ethernet SFP transceivers that interconnect network devices over large
distances using fiber optic cable. Figure 9 illustrates an SFP transceiver.

Chapter 1: Overview
Note
XFP Transceiver Slots
The x600-24Ts/XP and the x600-48Ts/XP Switches have two slots for
optional XFP 10 Gigabit Ethernet transceivers to connect high speed, 10
gigabit devices to the switch or create high speed backbone networks
between switches.
Figure 10 shows an example of an XFP transceiver.

Redundant Twisted Pair Ports
Four of the twisted pair ports on the x600-24-Ts and x600-24-Ts/XP
switches are paired with SFP slots. The twisted pair ports are identified
with the letter “R” for “Redundant” as part of their number on the faceplate
of the unit. The ports and slots are listed in Table 2.
Table 2. Twisted Pair Ports Matched with SFP Slots

x600-24Ts/XP
21R with SFP slot 21
22R with SFP slot 22
23R with SFP slot 23
24R with SFP slot 24
Follow these guidelines when using these ports and slots:
Only one port in a pair can be active at a time. It can be either the
twisted pair port or the corresponding SFP module.
The twisted pair port is the active port when its SFP slot is empty, or
when an SFP module is installed but has not established a link to an
end node.
The twisted pair port automatically changes to the redundant status
mode when an SFP module establishes a link with an end node.
A twisted pair port automatically transitions back to the active status
when the link is lost on the SFP module.
In nearly all cases, a twisted pair port and an SFP module share the
same configuration settings, including port settings, VLAN
assignments, access control lists, and Spanning Tree Protocol
settings.
An exception to the shared settings is port speed. If you disable Auto-
Negotiation on a twisted pair port and set the speed and duplex mode
manually, the speed reverts to Auto-Negotiation when an SFP module
establishes a link with an end node.

Port LEDs
A twisted pair port has two LEDs labeled L/A (link/activity) and D/C (duplex
mode/collisions). The L/A LED indicates the speed and activity on a port.
The D/C LED indicates the duplex mode (full- or half-duplex) and the
status of collisions on the port.
The twisted pair port LEDs appear on the right side of the x600-24Ts and
x600-24Ts/XP faceplates. On the x600-48Ts and x600-48Ts/XP
faceplates, the twisted pair port LEDs are interspersed among the twisted

The auto-MDI/MDI-X feature on the twisted pair ports automatically
configures the MDI/MDI-X setting when a link is established with an
end node. Available when a port is at the default setting of AutoNegotiation, this feature allows you to use a straight-through twisted
pair cable when connecting any type of network device to a port.
Disabling Auto-Negotiation on a port and setting the speed and
duplex mode manually also disables the auto-MDI/MDI-X feature. A
port where Auto-Negotiation has been disabled defaults to MDI-X.
Disabling Auto-Negotiation may require manually configuring a
port’s MDI/MDI-X setting or using a crossover cable.
A 10/100/1000Base-T twisted pair port must be set to Auto Negotiation to operate at 1000 Mbps. You cannot manually set the

Installing Optional Transceivers
Review the following guidelines before installing an optional SFP or XFP
transceiver in a switch:
A transceiver can be hot-swapped; the switch can be powered on
when you install it. However, you should always disconnect the cables
first before removing a transceiver.
You must install the transceiver before you connect the cables to it.
Fiber optic transceivers are dust sensitive. When a fiber optic cable is
not installed, or when you store the transceiver, always keep the plug
in the optical bores. When you do remove the plug, keep it for future
use.
Unnecessary removal and insertion of a transceiver can lead to
premature failure.
Installing an SFP
Transceiver
A transceiver can be damaged by static electricity. Be sure to
observe all standard electrostatic discharge (ESD) precautions,
such as wearing an antistatic wrist strap, to avoid damaging the
device.
To install an SFP transceiver in an x600 switch, perform the following
procedure:
1. Remove the dust plug from a transceiver slot on the switch, as shown
in Figure 22.
46
Figure 22. Removing a Dust Plug from an SFP Slot
2. Remove the transceiver from its shipping container and store the
packaging material in a safe location.
3. Position the transceiver with the label facing up.
4. Slide the transceiver into the slot until it clicks into place.

7. Repeat this procedure to install another SFP transceiver or go to
“Cabling the Twisted Pair and Fiber Optic Ports” on page 51.
For SFP optical and cabling specifications, consult the documentation
shipped with the module.
Observe the following guidelines when connecting a twisted pair or fiber
optic cable to a port on the switch:
The connector on the cable should fit snugly into the port on the
switch. The tab on the connector should lock the connector into place.
Because the twisted pair ports on the switch are auto-MDI/MDI-X, any
type of network device can be connected to a port on the switch using
a straight-through twisted pair cable. If you disable Auto-Negotiation
on the port, the port defaults to MDI-X.
If your network topology contains a loop where two or more network
devices can communicate with each other over more than one network
path, do not connect the network cables forming the loop until you
have activated a Spanning Tree Protocol on the switch. Data loops can
adversely affect network performance.
In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end node, the end node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A switch
port using Auto-Negotiation defaults to half-duplex if it detects that the
end node is not using Auto-Negotiation. This can result in a mismatch
if the end node is operating at a fixed duplex mode of full-duplex.
To avoid this problem, disable Auto-Negotiation on a switch port and
set the port’s speed and duplex mode manually if the end node has a
fixed duplex mode of full-duplex.

Chapter 4: Troubleshooting
Power LED is Off
Check the PWR LED on the front of the switch. If the LED is off, indicating
that the unit is not receiving power, do the following:
Make sure the power cord is securely connected to the power source
and to the AC connector on the back panel of the switch.
Verify that the power outlet has power by connecting another device
to it.
Connect the unit to another power source.
Use a different power cord.
Check that the voltage from the power source is within the required
levels for your region.
56
Twisted Pair Port Link LED is Off
Note
When a twisted pair port on the switch is connected to a properly operating
end node, the Link LED for the port should be on. If a Link LED is off, do
the following:
A 1000Base-T connection can take from five to ten seconds to
establish a link.
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the twisted pair cable is securely connected to the port on
the switch and to the port on the end node.
Make sure that the twisted pair cable does not exceed 100m (328 ft).
Verify that you are using the appropriate category of twisted pair cable.
Determine if a crossover cable is required. Since the twisted pair ports
feature auto MDI/MDI-X, you should be able to use a straight-through
cable regardless of the type of device you connect to a port. However,
if you disable Auto-Negotiation on a port and set a port’s speed and
duplex mode manually, the port defaults to MDI-X. Disabling AutoNegotiation may require manually configuring a port’s MDI/MDI-X
setting or using a crossover cable.
Make sure that the operating parameters of a port on the switch are
compatible with the end node to which the port is connected. This may
require using the switch’s operating system software.
For a switch port to successfully Auto-Negotiate its duplex mode with
an end node, the end node should also be using Auto-Negotiation.
Otherwise, a duplex mode mismatch can occur. A switch port using
Auto-Negotiation defaults to half-duplex if it detects that the end node
is not using Auto-Negotiation. This can result in a mismatch if the end
node is operating at a fixed duplex mode of full-duplex.
To avoid this problem, disable Auto-Negotiation on a switch port and
set the port’s speed and duplex mode manually if the end node has a
fixed duplex mode of full-duplex.
The switch has a bad cable detection feature that enables it to
determine if a twisted pair cable has a electrical short that might cause
a network loop. If the switch detects a bad cable on a port, it does not
establish a link on that port. In this situation, replace the cable.
57
Chapter 4: Troubleshooting
Note
SFP or XFP LED is Off
When a fiber optic port on the switch is connected to a properly operating
end node, the Link LED for the port should be on. If a Link LED is off, do
the following:
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the fiber optic cable is securely connected to the port on
the switch and the port on the end node.
If the fiber optic port is on a SFP or XFP transceiver, check that the
transceiver is firmly inserted into the slot on the switch.
Make sure that you are using the appropriate type of fiber optic cable
and that the cable length does not exceed the allowed maximum
distance. For cable specifications for an SFP transceiver, refer to the
installation instructions shipped with the module.
Use a fiber optic tester to test the attenuation on the cable and the
strength of the optical signal. For operating specifications for an SFP
transceiver, refer to the installation instructions shipped with the
module.
Check that the operating specifications (for instance, wavelength and
maximum operating distance) of the fiber optic port on the remote end
node are compatible with the fiber optic port on the switch.
Check that the fiber optic ports on the switch and on the end node are
operating at the same speed and duplex mode.
A fiber optic cable contains two separate fiber strands. One strand is
for receiving data and the other is for transmitting data. When you
connect a fiber optic cable to a port, be sure that the receive fiber
connector is connected to the transmit connector on the remote end
node. In addition, check that the transmit fiber connector is connected
to the receive connector on the remote node.
The L/A LED for an SFP transceiver slot may remain ON if you
remove the transceiver when it has a link to an end node without first
disconnecting the fiber optic cable. The L/A LED will change to OFF
the next time an SFP module is installed in the slot. To avoid this,
always disconnect the fiber optic cable before removing a
transceiver.
Transceiver is Installed but the Status is “Not Present”
If a SFP or XFP transceiver is installed in a transceiver slot but the Uplink
Information menu in the AlliedWare Plus
TM
Operating System Software
interface displays “Not Present” for that port, do the following:
Verify that the transceiver is completely inserted in the slot on the front
of the switch.
The uplink status does not reflect whether a fiber optic cable is
connected to the transceiver.

Chapter 4: Troubleshooting
System Fault LED is Blinking
If the system FAULT LED is blinking, no action is required. A blinking
FAULT LED could indicate that a new version of the operating system
software is in the process of being downloaded to the switch or the switch
is updating the active boot configuration file. The LED stops blinking after
the switch has completed downloading the operating system software or
updating the boot configuration file.
60
System Fault LED is Steadily On
Note
If the system FAULT LED is steadily on, a problem has occurred in the
switch. Do the following:
Reset the switch by disconnecting and reconnecting the AC power
cord.
If the FAULT LED remains ON, download a new version of the switch’s
operating system software. For instructions, refer to the AlliedWare
TM
Plus
Operating System Software Reference Guide.
If the FAULT LED remains steadily on, contact Allied Telesis
Technical Support for assistance. See “Contacting Allied Telesis” on
page 12.
Cannot Establish a Local (Out-of-Band) Management Session
If you are unable to establish a local (out-of-band) management session
with the switch through the terminal port on the front panel, do the
following:
Check that the RJ-45 serial management cable is securely connected
to the serial terminal port on the switch and to the RS-232 port on the
terminal or personal computer.
Check that the operating parameters on the terminal or the terminal
emulation program have been set correctly. The default settings for the
RJ-45 serial terminal port can be found in “Starting a Local
Management Session” on page 45.
62
Switch Functions Intermittently
If a switch functions intermittently, check the system hardware status
through the management interface:
Note the current voltage for the power supply compared to the
optimum rating.
Verify that the system temperature is within the operating range.
Table 11 lists the pin signals when a port is operating in the MDI-X
configuration at 10 or 100 Mbps.

The MDI/MDI-X setting is established automatically when a port is set to
Auto-Negotiation. If a port’s speed and duplex are set manually, the MDI/
MDI-X setting defaults to the MDI-X setting.
