Introducing the Switch 408
The HP ProCurve Switch 408 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, the name of this switch will be abbreviated
as the Switch 408.
The Switch 408 has 8 auto-sensing 10/100Base-TX RJ-45 ports. 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.

Network Ports
The switch has 8 auto-sensing 10/100Base-TX ports with RJ-45
connectors. All ports, except port 8, are wired as MDI-X ports. Port 8
can operate as either MDI-X or MDI, as controlled by the MDI-X/MDI
Select button.
MDI-X/MDI Select Button
This button is used to select an MDI-X or MDI connection for port 8.
Selecting MDI enables port 8 to be used as a cascade port for
connecting to another switch or hub using straight-through cable.
Selecting MDI-X makes port 8 operate the same as the other ports.
They are used to connect computers, servers, printers and other end
nodes using straight-through cables.

Features
Features
The features of the Switch 408 include:
■8 auto-sensing 10/100Base-TX RJ-45 ports—all ports can sense
the connection speed, 10 Mbps or 100 Mbps, and automatically
operate at that speed
■one port includes an MDI-X/MDI selection button
■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
8000-entry address forwarding table
■auto-negotiation of half/full duplex on all ports
■auto-negotiation of flow control for ports operating at full duplex
■back-pressure flow control for ports operating at half 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 auto-
matically and stored in the Switch 408’s 8000-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.

1-7
Introducing the Switch 408
Switch Operation Overview
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.
■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 408 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
408 automatically recognizes the change and updates the address
table with the new port locations of the devices. Communication with
the connected devices is thereby automatically maintained.

Introducing the Switch 408
Switch Operation Overview
Simultaneous Network Communications
As a part of the traffic isolation benefits provided by the Switch 408
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 bandwidth.

Installation Procedures
Installation Procedures
Summary
Follow these easy steps to install your switch. The rest of this chapter
provides details on these steps.
1. Prepare the installation site. Make sure of the following:
• the network cabling is the correct type and length. See page
2-5.
• the network topology is correct. See page 2-10.
• no devices connected to the switch have a fixed full-duplex
configuration (they must be able to auto-negotiate the duplex
mode or be fixed at half duplex). See page 2-4.
Please see page 2-3 for some installation precautions.
2. 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 2-7.
3. Mount the switch. The Switch 408 can be mounted on any
horizontal surface. The optional mounting kit (5183-7210)
provides other options including mounting two switch units side-
by-side in a standard 19-inch telco rack or equipment cabinet.
4. Connect power to the switch. Once the switch is mounted,
plug in the AC power adapter. See page 2-9.
5. Connect the network devices. Using the appropriate network
cables, connect computers, servers, printers and other periph-
erals, and other network devices including other switches, hubs,
or routers to the switch ports. See page 2-9.
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.

Installing the Switch 408
Installation Procedures
Installation Precautions:
Follow these precautions when installing your Switch 408.
Cautions ■Make sure that the power source circuits are properly
grounded, then use the power adapter supplied with the
switch to connect it to the power source.
■When installing the switch, since the unit does not have
an On/Off power switch, an AC power outlet must be
located near the switch and should be easily accessible
in case the switch needs to be powered off.
■Make sure that the switch does not overload the power
circuits, wiring, and over-current protection. To deter-
mine the possibility of overloading the supply circuits,
add together the amperage 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
amperage ratings are usually printed on the devices near
the AC power connectors or power adapter 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 of the switch is
not restricted.
■If you rack mount the Switch 408 (using the mounting kit,
5183-7210), the rack or cabinet should be adequately
secured to prevent it from 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 408
Installation Procedures
■Connect no devices that have a fixed full-duplex
configuration. Because the switch 408 complies with
the IEEE 802.3u standard, if a device connected to the
switch has a fixed configuration of full duplex, the device
will not connect correctly to the switch. Make sure all
devices connected to the Switch 408 are configured to
auto negotiate, or are configured to connect at half
duplex. For more information, see the “Basic Trouble-
shooting Tips” in chapter 3, “Troubleshooting”.
