Introducing the HP Switch 2224
The HP ProCurve Switch 2224 is a multiport switch that can be used to build
high-performance switched workgroup networks. This switch is a store-and-
forward device that offers low latency for high-speed networking.
Throughout this manual, this switch will be abbreviated as the Switch 2224.
The Switch 2224 has 24 auto-sensing 10/100Base-T RJ-45 ports, and a slot for
installing an HP 100Base-FX fiber-optic transceiver.
With this switch you can build a switched network infrastructure by
connecting it to hubs, other switches, or routers; or you can connect directly
to computers, printers, and servers to provide dedicated bandwidth to those
devices.

LEDs
Table 1-1. Switch LEDs
Switch LEDs State Meaning
Power
(green)
On The switch is receiving power.
Off The switch is NOT receiving power.
Fault
(orange)
Off The normal state; indicates that there are no fault conditions on the switch.
Blinking†A fault has occurred on the switch, or the transceiver module (if installed). If the
transceiver is having the problem, the Port 1 Link LED will blink simultaneously.
On On briefly after the switch is powered on or reset, at the beginning of switch self test.
If on for a prolonged time, the switch has a hardware failure, or has failed its self test.
See chapter 3, “Troubleshooting” for more information.
Link
(green –
overlaid with
the port
number)
On Indicates the port is enabled and receiving a link beat signal (for the twisted-pair ports),
or a strong enough light level (for the fiber-optic ports) from the connected device.
Off One of these conditions exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
Mode
(green)
Displays network activity information, or whether the port is configured for full-duplex operation, or
100 Mbps operation depending on the mode selected. See “Mode Select Button and Indicator LEDs”
on the next page for more information.
Mode Select
indicators
(3 green LEDs)
Act Indicates that the port Mode LEDs are displaying network activity information.
Fdx Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
100 Indicates that the port Mode LEDs are lit for ports that are operating at 100 Mbps.
Port 1
indicator LED
(green)
On Indicates that a transceiver module is installed in the slot, and the switch is using the
transceiver as switch Port 1.
Off A transceiver module is not installed in the switch, and the fixed Port 1 RJ-45 connector
is being used as switch Port 1.
†The blinking behavior is an on/off cycle once every 1.6 seconds, approximately.

Mode Select Button and Indicator LEDs
To optimize the amount of information that can be displayed for each of the
switch ports without overwhelming you with LEDs, the Switch 2224 uses a
Mode LED for each port. The operation of this LED is controlled by the Mode
Select button, and the current setting is indicated by the Mode indicator LEDs
near the button. Press the button to step from one mode to the next.
■If the Activity (Act) indicator LED is lit, the Mode LED for each port
displays activity information for the port—it flickers as network traffic is
received and transmitted through the port.
■If the Full Duplex (Fdx) indicator LED is lit, the Mode LEDs light for those
ports that are operating in full duplex.
■If the 100 Mbps (100) indicator LED is lit, the Mode LEDs light for those
ports that are operating at 100 Mbps.
Port 1 Indicator LED
The LED labeled “100FX Port used as Port 1” indicates which of the switch
ports, the transceiver module or the fixed RJ-45 connector is being used as
the switch Port 1. Only one of these ports can be active at any time. If a
transceiver module is installed, it will automatically be selected by the switch
to be used for Port 1, and the LED will be lit, even if there is no active fiber-
optic cable connected to the transceiver.
If a non-supported transceiver is installed in the switch, for example a
100Base-TX twisted-pair transceiver, this LED remains off.
