Overview of the Gigabit
Ethernet Modules
The Intel® NetStructure™ 6000 switch has two Gigabit Ethernet
modules. One is a 1000Base-SX card and the other is a 1000BaseLX/1000Base-SX card.
1000Base-SX Module
The chassis can house up to four 1000SX Gigabit Ethern et modules.
Each Gigabit Ethernet module has eight switched ports.
Each port operates in full-duplex mode only, and can be put in autonegotiation mode for flow control parameters.
Setting Auto-negotiation
10
Auto-negotiation makes it possible for devices to exchange
information about their abilities over a link seg m ent. This function
allows the devices at both ends of a li nk segment to advertise abil ities
and acknowledge receip t and understa nding of the common mo des of
operation that both devices share.
The default setting for the switch has auto-negotiation enabled on all
of the ports.
1 Type show link aut on eg port_number to display the auto-nego-
tiation parameters for a link.
2 Type the privileged set link port_number noautoneg command
to disable auto-negotiation on a port.
The Gigabit Ethernet module supports full-duplex mode only.
Note If auto-negotiation is not enabled for a remote partner of a
6000 switch port and another Gigabit Ethernet device, autonegotiation must be disabled.
Only devices configured for full-duplex mode may send pause
frames. Pause frames provide flow control over full-duplex links.

C H A P T E R 3 Intel® NetStructure™ 6000 Switch Modules User Guide
Overview of the Fast Ethernet
Modules
The Intel® NetStructure™ 6000 switch has two Fast Ethernet
modules. One is a 100Base-TX card which can upgrade your Ethernet
network to Fast Ethernet by supporting both 10Mbps and 100Mbps
on each switched port.
The other module is a 100Base-FX card which can directly upgrade
your Ethernet network to 100Mbps.
10/100 Ethernet Module
This module is a 24-port 100Base-T X Ethernet card. It supports fulland half-duplex 10 and 100Mbps data transfer and auto-negotiation.
Setting Auto-negotiation
16
Auto-negotiation allows each end of a link to query the other to
determine a compatible mode of operation. For example, if both links
support full-duplex operation, then the switch can determine this
mode.
When a link becomes active, the switch determines the highest
throughput mode of operation between the two devices.
The Control Process (CP) software also includes commands that
allow the speed an d duplex of the port s to be manually set.
Note The default setting is “autoneg 100 10 full half.” The link
uses autonegotiati on to choose the best mod e. This is usually the best setting unless th e remote par tner is not working
properly. When the remote partner is not capable of autonegotiation, the port autosenses the speed and defaults to half
duplex.
Type the privileged set link port_number options command, where
port_number i s one o f t he globa l ports o n th e chassis and options are
autoneg or noautoneg, 10, 100, half or full.
Example
Intel Switch>#>set link 6 100 FULL no autoneg
C H A P T E R 3 Fast Ethernet Modules
The link configuration is stored in non-vo latile memory. This allows
the current setting to be restored upon the next reset.
The set link port_number defaults command restores the factor y
default link settings to the switch.
T ype the non- privileged show link port_number command to display
the current state of the link.

The module uses 24 RJ-45 modular receptacles for 100Base-TX
switched Fast Ethernet transmissions over Category 5 UTP.
According to IEEE 802.3, the cable length must not exceed 100
meters (328.1 feet).
Light Emitting Diodes (LEDs) provide status information for the
module and individual port connections.

10/100 Ethernet Troubleshooting
Power-up Problems
The following table is a quick guide to power-up problems, their
possible cause, and a suggested course of action.
Possible
Symptom
Cause Course of Action
No Link LED after
plugging in a cable.
Bad or improper
cable type.
Ports are
configured
improperly.
Check cable. 100Mbps
link requires Category 5
cable. Hub-to-switch or
switch-to-switch
connection must be made
with a “crossover” cable.
Check patch cables
especially. Never use
“silver satin” telephone
patch cables. The total
length of the cable should
be less than 100 meters
(328.1 feet) including
patches.
The switch’s default link
connects with any
properly operating lin k.
However, a port can be
configured to link without
auto-negotiation into one
of several configurations.
If plugged into a port that
has been configured
differently, the link might
not connect or might not
work properly. For
example, a full-duplex
port connected to a halfduplex port might have
many frame errors.The
best solution is to use the
ports in auto-negotiation
mode with properly
functioning d evices
plugged into them.
18
C H A P T E R 3 Fast Ethernet Modules
Possible
Symptom
Cause Course of Action
No connectivity
with a station on a
switch port.
Poor performance
on a link.
No link. Link on
10/100 module is
off.
Cable has just
been moved from
one port to
another.
Spanning Tree
has just been
enabled.
A considerable
amount of Data
Link errors such
as CRC errors.
T oo many
collisions.
See “No Link LED”
symptom above.
Test for connectivity with
the ping command.
Use the clear fdb
command or wait until the
aging time has expired if
the destination is not
generating traffic. The set
agingtime command
establishes the aging time.
Wait 60 seconds for state
to change to “forwarding.”
Use the show counters
command to display them.
Or, use any SNMP-based
network management tool
to generate reports based
on these counters.
Too many stations on the
segment. Try moving
some to their own
segment.
Late Collisions. Cables are too long. Use a
shorter cable, or add a
repeater or bridge.
There are too many
“hops.” Use fewer devices
from end to end.
