Installation Precautions
WARNING ■ Wall-mount the switches with network ports facing up (away from
the floor) or down (toward the floor). Do not wall-mount any of
the switches with the ventilation ducts facing up or down.
Cautions ■ Use only the AC/DC power adapter supplied with the switch for
connection to an AC power source.
■ If your installation requires a different power cord than the one supplied
with the switch, ensure the cord is adequately sized for the switch’s
current requirements. In addition, be sure to use a power cord displaying
the mark of the safety agency that defines the regulations for power cords
in your country. The mark is your assurance that the power cord can be
used safely with the switch. If the supplied power cord does not fit,
contact HP networking support.
■ When installing the switch, the AC outlet should be near the switch and
should be easily accessible in case the switch must be powered off.
■ Ensure the switch does not overload the power circuits, wiring, and
over-current protection. To determine the possibility of overloading the
supply circuits, add together the ampere ratings of all devices installed on
the same circuit as the switch and compare the total with the rating limit
for the circuit. Maximum ampere ratings areusually printed on thedevices
near the AC power connectors.
■ Do not install the switch in an environment where the operating ambient
temperature might exceed 40°C (104°F). This includes a fully-enclosed
rack. Ensure the air flow around the sides and back of the switch is not
restricted. Leave at least 7.6 cm (3 inches) for cooling.
■ For indoor use only. For safe and reliable operation, do not install the
switch or LAN cables outdoors.

Installation Procedures
LED Behavior
After Initialization:
• The Power LED remains on.
• The port Link/Act LEDs on the front of the switch go into their normal
operational mode:
– If the ports are connected to active network devices, the Link/Act
LEDs stay on or may be blinking to indicate port activity.
– If the ports are not connected to active network devices, the
Link/Act LEDs will stay off.
If the LED display is different than what is described above, the self test
has not completed correctly. Refer to chapter 4, “Troubleshooting” for
diagnostic help.
3. Mount the Switch
After the switch passes self test, it is ready to be mounted in a stable location.
The switch can be mounted in these ways:

Figure 2-7. Basic configuration
The switches are designed to be used as desktop switches to which end nodes,
printers and other peripherals are directly connected, as shown in the above
illustration.
Because the switches have the Auto-MDIX feature, the connections between
the switches and end nodes or servers can be through category 5
straight-through or cross-over twisted-pair cable. Category 3 or 4 cable can
also be used if the connection is 10 Mbps only.

Troubleshooting
This chapter describes how to troubleshoot your 1405-5 Switch, 1405-5G
Switch, 1405-8 Switch, and 1405-8G Switch. This document describes
troubleshooting from a hardware perspective.
This chapter describes the following:
■ basic troubleshooting tips (page 3-1)
■ diagnosing with the LEDs (page 3-3)
■ hardware diagnostic tests (page 3-5)
■ HP Customer Support Services (page 3-6)
Basic Troubleshooting Tips
3
Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:
■ Connecting to devices that have a fixed full-duplex configuration.
The RJ-45 ports are configured as “Auto”. That is, when connecting to
attached devices, the switch operates in one of two ways to determine the
link speed and the communication mode (half duplex or full duplex):
• If the connected device is also configured to Auto, the switch will
automatically negotiate both link speed and communication mode.
• If the connected device has a fixed configuration, for example
100 Mbps,
the link speed, but will default to a communication mode of half
duplex.
at half or full duplex, the switch will automatically sense
Caution Because the switches behave in this way (in compliance with the IEEE
802.3 standard), if a device connected to the switch has a fixed
configuration at full duplex, the device will not connect correctly to the
switch. The result will be high error rates and very inefficient
communications between the switch and the device.
Ensure all devices connected to the switches are configured to auto
negotiate, or are configured to connect at half duplex (all hubs are
configured this way, for example).
3-1
Troubleshooting
Basic Troubleshooting Tips
■ Faulty or loose cables. Look for loose or obviously faulty connections.
If the cables appear to be OK, make sure the connections are snug. If that
does not correct the problem, try a different cable.
■ Non-standard cables. Non-standard and miswired cables may cause
network collisions and other network problems, and can seriously impair
network performance. Use a new correctly-wired cable or compare your
cable to the cable in appendix A, “Cabling and Technology Information
Specifications”
for pinouts and correct cable wiring. A category 5 cable
tester is a recommended tool for every 100Base-TX and 1000Base-T
network installation.
■ Improper Network Topologies. It is important to make sure you have
a valid network topology. Common topology faults include excessive
cable length and excessiverepeater delays betweenend nodes. If youhave
network problems after recent changes to the network, change back to
the previous topology. If you no longer experience the problems, the new
topology is probably at fault.
In addition, you should make sure that your network topology contains
no data path loops. Between any two end nodes, there should be only
one active cabling path at any time. Data path loops will cause broadcast
storms that will severely impact your network performance.

Diagnosing with the LEDs
Table 3-1 shows LED patterns on the switch that indicate problem conditions
for general switch operation troubleshooting.
LED patterns for General Switch Troubleshooting
1. Check in the table for the LED pattern you see on your switch.
2. Refer to the corresponding diagnostic tip on the next few pages.

The switch is not
plugged into an
active AC power
source, or the
switch’s power
supply may have
failed.
The network
connection is not
working
properly.
1. Verify the power cord is plugged into an active power source and to the switch. Make
sure these connections are snug.
2. Try power cycling the switch by unplugging and plugging the power cord back in.
3. If the Power LED is still not on, verify the AC power source works by plugging another
device into the outlet. Or try plugging the switch into a different outlet or try a different
power cord.
If the power source and power cord are OK and this condition persists, the switch power
supply may have failed. Call your HP networking authorized network reseller, or use the
electronic support services from HP to get assistance. For software license, warranty,
and support information, visit www.hp.com/networking/support.
Try the following procedures:
• For the indicated port, verify that both ends of the cabling, at the switch and the
connected device, are connected properly.
• Verify the connected device and switch are both powered on and operating correctly.
• Verify you have used the correct cable type for the connection:
– For twisted-pair connections to the fixed 10/100/1000 ports, either straight-through
or cross-over cables can be used because of the switch’s “Auto-MDIX” feature
and the Auto MDI/MDI-X feature of the 10/100/1000-T port.
• For 1000Base-T connections, verify the network cabling complies with the IEEE 802.3ab
standard. The cable should be installed according to the ANSI/TIA/EIA-568-A-5
specifications. Cable testing should comply with the stated limitations for Attenuation,
Near-End Crosstalk, Far-End Crosstalk, Equal-Level Far-End Crosstalk (ELFEXT),
Multiple Disturber ELFEXT, and Return Loss.
The cable verification process must include all patch cables from any end devices,
including the switch, to any patch panels in the cabling path.
• Verify the switch port configuration of the attached device. All switch ports are
configured as “Auto”, so ports on the attached device also MUST be configured as
“Auto”. Depending on the port type, twisted-pair or fiber-optic, if the configurations
do not match, the results could be a very unreliable connection, or no link at all.
• If the other procedures don’t resolve the problem, try using a different port or a different
cable.

Hardware Diagnostic Tests
Troubleshooting
Hardware Diagnostic Tests
Testing the Switch by Resetting It
If you believe the switch is not operating correctly, you can reset the switch
to test its circuitry and operating code. To perform a reset, power cycle the
switch; unplug the power cord, wait 2 seconds, then reconnect power.
Power cycling the switch causes the switch to perform its power-on self test.
Testing Twisted-Pair Cabling
Network cables that fail to provide a link or provide anunreliable link between
the switch and the connected network device may not be compatible with the
IEEE 802.3 Type10Base-T, 100Base-TX, or 1000Base-Tstandards. The twistedpair cables attached to the switch must be compatible with the appropriate
standards. To verify your cable is compatible with these standards, use a
qualified cable test device.
Testing End-to-End Network Communications
Both the switch and the cabling can be tested by running an end-to-end
communications test—a test that sends known data from one network device
to another through the switch. For example, if you have two PCs on the
network that have LAN adapters between which you can run a link-level test
or Ping test through the switch, you can use this test to verify that the entire
communication path between the two PCs is functioning correctly. See your
LAN adapter documentation for more information on running a link test or
Ping test.

Twisted-pair copper
10 Mbps Operation Category 3, 4 or 5, 100-ohm unshielded twisted-pair (UTP) or
shielded twisted-pair (STP) cable, complying with IEEE 802.3
10BASE-T specifications.
100 Mbps Operation Category 5, 100-ohm UTP or STP cable, complying with IEEE 802.3u
100BASE-TX specifications.
1000 Mbps Operation Category 5, 100-ohm 4-pair UTP or STP cable, complying with IEEE
802.3ab 1000BASE-T specifications—Category 5e or better is
recommended. See note on 1000BASE-T Cable Requirements
below.
Note on 1000BASE-T Cable Requirements. The Category 5 networking
cables that work for 100BASE-TX connections should also work for
1000BASE-T, as long as all four-pairs are connected. But, for the most robust
connections, you should use cabling that complies with the Category 5e
specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/
TIA/EIA-568-A-5).
Because of theincreased speed providedby 1000BASE-T (Gigabit-T),network
cable quality is more important than for either 10BASE-T or 100BASE-TX.
Cabling plants being used to carry 1000BASE-T networking must comply with
the IEEE 802.3ab standards. In particular, the cabling must pass tests for
Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT).
Additionally, unlike the cables for 100BASE-TX, the 1000BASE-T cables must
pass tests for Equal-Level Far-End Crosstalk (ELFEXT) and Return Loss.
When testing your cabling, be sure to include the patch cables that connect
the switch and other end devices to the patch panels on your site. The patch
cables are frequently overlooked when testing cable and they must also
comply with the cabling standards.

Twisted-Pair Cable/Connector Pin-Outs
Twisted-Pair Cable/Connector Pin-Outs
The Auto-MDIX Feature: In the default configuration, “Auto”, the fixed 10/
100/1000Base-T ports on the switches all automatically detect the type of port
on the connected device and operate as either an MDI or MDI-X port,
whichever is appropriate. So for any connection, a straight-through twistedpair cable can be used—you no longer have to use crossover cables, although
crossover cables can also be used for any of the connections. (The 10/100/
1000-T ports support the IEEE 802.3ab standard, which includes the “AutoMDIX” feature.)
If you connect a switch twisted-pair port to another switch or hub, which
typically have MDI-X ports, the switch port automatically operates as an MDI
port. If you connect it to an end node, such as a server or PC, which typically
have MDI ports, the switch port operates as an MDI-X port. In all cases, you
can use standard straight-through cables or crossover cables.
If you happen to use a correctly wired crossover cable, though, the switch will
still be able to automatically detect the MDI/MDI-X operation and link
correctly to the connected device.
Note Using Fixed Configurations. If the port configuration is changed to any of
the fixed configurations though, for example 100 Mbps/full duplex, the port
operates as MDI-X only and the correct cable type must be used: for
connections to MDI ports, such as end nodes, use a straight-through cable; for
connections to MDI-X ports, such as on hubs and other switches, use a
crossover cable.
Other Wiring Rules:
■ All twisted-pair wires used for 10 Mbps, and 100 Mbps operation must be
twisted through the entire length of the cable. The wiring sequence must
conform to EIA/TIA 568-B (not USOC). See “Twisted-Pair Cable Pin
Assignments” later in this appendix for a listingof the signals used oneach
pin.
■ For 1000Base-T connections, all four pairs of wires in the cable must be
available for data transmission.
■ For 10 Mbps connections to the ports, you can use Category 3, 4, or 5
unshielded twisted-pair cable, as supported by the IEEE 802.3 Type
10Base-T standard.

Twisted-Pair Cable/Connector Pin-Outs
Straight-through Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connections
Because of the Auto-MDIX operation of the 10/100 ports on the switch, for all
network connections, to PCs, servers or other end nodes, or to hubs or other
switches, you can use straight-through cables.
If any of these ports are given a fixed configuration, for example 100 Mbps/
Full Duplex, the ports operate as MDI-X ports, and straight-through cables
must be then used for connections to PC NICs and other MDI ports.
