Introducing the Switch
The ProCurve Switches 3400cl are multiport switches thatcan be usedto build
high-performance switched workgroup networks. These switches are store-
and-forward devices offering low latency for high-speed networking.
Throughout this manual, this switch will be abbreviated as the Switch 3400cl-
24G or Switch 3400cl-48G and collectively as the Series 3400cl Switch devices.
The Switch 3400cl-24G and Switch 3400cl-48G have respectively, 24 or 48,
auto-sensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports—
either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC, and one slot is
provided in the back of the device to support a two port 10 Gigabit per second
Ethernet (10-GbE) module to provide box connectivity to other switch boxes,
to a 10 Gigabit per second concentrator or to any Ethernet compatible uplink.
The Series 3400cl Switch devices can be connected to a ProCurve
RPS/EPS (J8168A) and receive full redundant power from that unit. If the
internal power supply in the switch fails, the RPS/EPS unit will immediately
provide all the power necessary to keep the switch running.

Introducing the Switch
Introducing the Switch
These switches are designed to be used primarily as a high-density wiring
closet or desktop switch. These switches can directly connect computers,
printers, and servers to provide dedicated bandwidth to those devices, and can
build a switched network infrastructure by connecting the switch to hubs,
other switches, or routers. In addition, the Series 3400cl Switch devices offer
full network management capabilities.
This chapter describes the Series 3400cl Switch devices, including:

Network Ports
■24 or 48 auto-sensing 10/100/1000Base-T ports.
All these ports have the “HP Auto MDIX” feature, which means you can
use either straight-through or crossover twisted-pair cables to connect
any network devices to the switch.
■Four dual-personality ports. Use either the 10/100/1000Base-T RJ-45
connector, or install a supported ProCurve mini-GBIC for fiber-optic
connections.
The RJ-45 connectors support the IEEE Auto MDI/MDI-X feature, which
means you can use either straight-through or crossover twisted-pair
cables to connect any network device to the switch.
Dual-Personality Port Operation. By default, the RJ-45 connectors are
enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated
RJ-45 connector is disabled and cannot be used. If the mini-GBIC is
removed, the associated RJ-45 port is automatically re-enabled.
■One, 10 gigabit expansion slot. These switches provide a single slot in the
back of the device that can accept a 2 x 10 gigabit transceiver module. The
module provides two 10 gigabit ports. The module may provide either
copper or fiber optic media that conforms to the gigabit Ethernet standard
as well as dual 10 gigabit copper or uplink ports.

Table 1-1. Switch LEDs
Switch LEDs State Meaning
Power
(green) On
Off
The switch is receiving power.
The switch is NOT receiving power.
Fault
(orange) Off The normal state; indicates there are no fault conditions on the switch.
Blinking* A fault has occurred on the switch, one of the switch ports, module in the rear of the
switch, or the fan. The Status LED for the component with the fault will blink
simultaneously.
On On briefly after the switch is powered on or reset, at the beginning of switch self test.
If this LED is on for a prolonged time, the switch has encountered a fatal hardware
failure, or has failed its self test. See chapter 4, “Troubleshooting” for more information.
Test
(green) Off The normal operational state; the switch is not undergoing self test.
On The switch self test and initialization are in progress after the switch has been power
cycled or reset. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you “hot swap” a mini-GBIC into the switch; the mini-GBIC
is self tested when it is hot swapped.
Blinking* A component of the switch has failed its self test. The status LED for that component,
for example an RJ-45 port, and the switch Fault LED will blink simultaneously.
Port LEDs
(green – over-
laid with the
port number)
Displays port link information, network activity information, whether the port is configured for full-
duplex operation, or the speed of the connection depending on the Port LED View selected. See “Port
LED View Select Button and Indicator LEDs” on the next page for more information. If a fault has
occurred on the port, the port LED will blink with the Fault LED.
LED Mode

LEDs)
Link Indicates the port LEDs are displaying link information:
• if the port LED is on, the port is enabled and receiving a link indication from the
connected device.
• if the port LED is off, the port has no active network cable connected, or is not
receiving link beat or sufficient light. Otherwise, the port may have been disabled
through the switch console, the web browser interface, or ProCurve Manager.
• if the port LED is blinking* simultaneously with the Fault LED, the corresponding port
has failed its self test.
Act Indicates the port LEDs are displaying network activity information.
FDx Indicates port LEDs are lit for ports in Full Duplex Mode. Off indicates ½duplex.
Spd Indicates the port LEDs are displaying the connection speed at which each port is
operating:
• if the port LED is off, the port is operating at 10 Mbps.
• if the port LED is flashing**, the port is operating at 100 Mbps.
• if the port LED is on continuously, the port is operating at 1000 Mbps.
** The flashing behavior is an on/off cycle once every 0.5 seconds, approximately.

LED Mode Select Button and Indicator LEDs
To optimize the amount of information displayed for each of the switch ports
without overwhelming you with LEDs, the Series 3400cl Switch devices use a
single LED for each port. The operation of this LED is controlled by the LED
Mode select button, and the current setting is indicated by the LED Mode
indicator LEDs near the button. Press the button to step from one view mode
to the next.

■If the Link (Lnk) indicator LED is lit, each port LED displays link infor-
mation for the associated port.
If the port LED is in Link mode and it is blinking, the port has failed its
self test. The Fault and Self Test LEDs will be blinking simultaneously.
■If the Activity (Act) indicator LED is lit, each port LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those
ports that are operating in full duplex.
■If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle
once every 0.5 sec.)
• On = 1000 Mbps
Reset Button
This button is used to reset the switch while it is powered on. This action clears
any temporary error conditions that may have occurred and executes the
switch self test.
Clear Button
This button is used for these purposes:
■Deleting Passwords - When pressed by itself for at least one second, the
button deletes any switch console access passwords that you may have
configured. Use this feature if you have misplaced the password and need
console access.
This button is provided for your convenience, but its presence means that
if you are concerned with the security of the switch configuration and
operation, you should make sure the switch is installed in a secure
location, such as a locked wiring closet.
■Restoring Factory Default Configuration - When pressed with the
Reset button in a specific pattern, any configuration changes you may
have made through the switch console, the web browser interface, and
SNMP management are removed, and the factory default configuration is
restored to the switch. For the specific method to restore the factory
default configuration, see “Restoring the Factory Default Configuration”
on page 11, in chapter 4, “Troubleshooting” of this manual.

Expansion Module LEDs
“Expansion Module” LEDs refer to the LEDs specific to the expansion module.
These LEDs are located on the physical expansion module bulkhead. These
LEDs are only viewable in the rear of the Switch 3400cl-48G product on the
Expansion Slot Module itself.
Table 1-3. Expansion Module LEDs
Expansion module LEDs for port A and B operate in modes for Link and
Activity. FDx and Spd modes have no meaning for the 10-GbE ports on the
expansion module.
Caution It is recommended the power to the switch be removed before inserting or
extracting the Expansion Module.

Blinking
Indicates that the port LEDs are displaying link information:
• if the port LED is on, the port is enabled and receiving a link indication
from the connected device.
• if the port LED is off, the port has no active network cable connected,
or is not receiving link beat or sufficient light. Otherwise, the port may
have been disabled through the switch console, the web browser
interface, or ProCurve Manager.
• if the port LED is blinking* simultaneously with the Fault LED, the
corresponding port has failed its self test.
Act Green On Indicates the port LEDs are displaying network activity information.
* The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

Console Port
This port is used to connect a console to the switch by using the serial cable
supplied with the switch. This connection is described under “Connect a
Console to the Switch” in chapter 2, “Installing the Switch.” The console can
be a PC or workstation running a VT-100 terminal emulator, or a VT-100
terminal. The console port is located on the front of the 3400cl-24G and on the
back of the 3400cl-48G.
Power Connector
The Series 3400cl Switch devices do not have a power switch; they are
powered on when connected to an active AC power source. These switches
automatically adjust to any voltage between 100--127 and 200--240 volts and
either 50 or 60 Hz. There are no voltage range settings required.

Switch Features
The features of the Series 3400cl Switch devices include:
■24 or 48 auto-sensing 10/1001000Base-T RJ-45 ports with HP Auto-MDIX.
■four dual-personality ports—either the auto sensing 10/100/1000Base-T
RJ-45 or the mini-GBIC can be used for each port.
■one slot (optional cl module slot) is provided in the back of the device to
support a series of transceivers to provide box connectivity to other
switch boxes, to a 10 Gig concentrator or to any Ethernet compatible
uplink.
■one auxiliary port is provided.
■The Series 3400cl Switch devices can be connected to a ProCurve
RPS/EPS (J8168A) and receive full redundant power from that unit. If the
internal power supply in the switch fails, the RPS/EPS unit will immedi-
ately provide all the power necessary to keep the switch running.
■plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■IEEE 802.3ab Auto MDI/MDI-X on all 10/100/1000-T twisted-pair ports,
meaning that all connections can be made using straight-through
twisted-pair cables. Cross-over cables are not required, although they
will also work. The pin operation of each port is automatically adjusted
for the attached device: if the switch detects that another switch or hub
is connected to the port, it configures the port as MDI; if the switch detects
that an end-node device is connected to the port, it configures the port as
MDI-X.
■automatic learning of the network addresses in each switch’s 8000-
address forwarding table, (with configurable address aging value).
■automatically negotiated full-duplex operation for the 10/100/1000-T RJ-
45 ports when connected to other auto-negotiating devices—the mini-
GBIC ports always operate at full duplex.
■easy management of the switch through several available interfaces:
•console interface—a full featured, easy to use, VT-100 terminal
interface that is especially good for out-of-band switch management
or for Telnet access to the switch.
•web browser interface—an easy to use built-in graphical interface
that can be accessed from common web browsers.
•ProCurve Manager—an SNMP-based, graphical network manage-
ment tool that you can use to manage your entire network. This
product is included with your new switch.
