Mode LEDs
(one per port)
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.
Mode Select button
and indicator LEDs
■ 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 fiberoptic 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.

Features
The features of the Switch 2224 include:
■ 24 auto-sensing 10/100Base-TX RJ-45 ports
■ a slot for installing an HP 100Base-FX Transceiver Module (HP J3193B)
■ plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational
■ automatic learning of the hardware addresses in the switch’s 12000-entry
address forwarding table
■ auto-negotiation of half/full duplex on all ports
■ auto-negotiation of flow control for ports operating at full duplex
Switch Operation Overview
Address Table Operation
Address Learning. As devices are connected to the switch ports, either
directly or through hubs or other switches that are connected to the switch,
the MAC addresses of those devices are learned automatically and stored in
the Switch 2224’s 12000-entry address table. The switch also identifies the
number of the port on which each address is learned so it knows the relative
network location of each device.
Forwarding, Filtering, Flooding. When the switch receives a packet, it
determines the destination address, and looks for the address in the address
table. Based on the port location of that address, the switch then determines
whether to forward, filter-out, or flood the packet.
■ forward - if the destination address is on a different port than the one on
which the packet was received, the packet is forwarded to the destination
port and on to the destination device.
■ filter out - if the destination address is on the same port as the one on
which the packet was received, the packet is filtered out. The switch
thereby isolates local traffic so the rest of the network connected to the
switch does not use bandwidth dealing with unnecessary traffic.
1-6
Ice.book Page 7 Monday, January 11, 1999 5:23 PM
Introducing the HP Switch 2224
Switch Operation Overview
■ flood - whenever a new destination address is found in a packet received
on a port, the destination address will not yet be in the switch’s address
table and the Switch 2224 cannot know whether to forward or filter out
the packet. In this case, it sends the packet to all the other switch ports.
This is referred to as “flooding”. When the destination device receives the
packet, it replies, and the switch learns the new address from the reply
packet. Then, all future packets destined for that address are forwarded
or filtered out appropriately.
Network Moves and Changes. When devices are moved in the network,
and become connected to a different switch port, the Switch 2224 automatically recognizes the change and updates the address table with the new port
location of the device. Communication with the device is automatically maintained, without any address table manipulation being required.
Simultaneous Network Communications
As a part of the traffic isolation benefits provided by the Switch 2224 address
table operation, the switch enhances network performance because it can
conduct multiple, simultaneous network connections. Instead of sharing the
network bandwidth, as in connections to a hub, each connection has its own
10 Mbps, or 100 Mbps.

easier to install the transceiver first.
Installing the Switch 2224
3. Verify that the switch passes its self test. This is a simple process of
plugging the switch into a power source and observing that the LEDs on
the switch’s front panel show correct operation. See page 1-3.
4. Mount the switch. The Switch 2224 can be mounted in a 19-inch telco
rack or equipment cabinet, on a wall, or on a horizontal surface.
5. Connect power to the switch. Once the switch is mounted, plug it in
to the nearby AC power source.
6. Connect the network devices. Using the appropriate network cables,
connect other switches, hubs, routers, computers, servers, printers, and
other network devices to the switch ports.
At this point, the switch is fully installed and your network should be up and
running. See the rest of this chapter if you need more detailed information on
any of these installation steps.

Installation Procedures
becoming unstable and/or falling over.
Devices installed in a rack or cabinet should be mounted as low as
possible, with the heaviest device at the bottom and progressively
lighter devices installed above.
Installing the Switch 2224
use the power cord supplied with the switch to connect it to the power
source.
If your installation requires a different power cord than the one
supplied with the switch, 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.
■ When installing the switch, since the unit does not have an On/Off power
switch, the AC power outlet must be located near the switch and should
be easily accessible in case the switch needs to be powered off.
■ Ensure that 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. The maximum ampere ratings are usually
printed on the devices near the AC power connectors.
■ Do not install the switch in an environment where the operating
ambient temperature might exceed 55°C (131°F).
■ Make sure the air flow around the sides and back of the switch is
not restricted.
■ Make sure that if no transceiver is installed in the transceiver slot, the
cover plate is installed to cover the slot. A cover plate is required for
safe operation, and to ensure proper switch cooling.
