Introducing the Switch 408
The 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 eight 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.

Features
Features
The features of the Switch 408 include:
■eight auto-sensing 10/100Base-TX RJ-45 ports—all ports can
sense the connection speed, 10 Mbps or 100 Mbps, and automat-
ically operate at that speed
■HP Auto-MDIX on all ports—all ports allow you to use either a
straight-through or crossover cable to connect to any other
RJ-45 network device. There are no switches or buttons to deal
with, and no more worrying about what type of cable is needed
to connect to an end node, or to another switch or hub.
■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
1000-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
matically and stored in the Switch 408’s 1000-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.
■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.

Installing the Switch 408
The ProCurve Switch 408 is easy to install. It comes with four rubber
feet that can be attached so the switch can be securely located on any
level surface (for example, a table or shelf). A mounting kit (5183-
7210) is also available that provides a variety of mounting options
including in a standard 19-inch EIA equipment rack or cabinet, on a
wall, or under a horizontal surface. Contact your HP Networking
products reseller to order the mounting kit.
This chapter shows you how to install your Switch 408.

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.
See page 2-3 for 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.

Installation Procedures
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.
Installation Precautions
Follow these precautions when installing your Switch 408:
Cautions ■Make sure you use the power adapter supplied with the
switch to connect it to an AC 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 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 40°C
(104°F).
■Make sure the air flow around the sides of the switch is
not restricted.
Continued on the next page.

2-4
Installing the Switch 408
Installation Procedures
■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.
■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”.

2-5
Installing the Switch 408
Installation Procedures
1. Prepare the Installation Site
■Cabling Infrastructure - Make sure the cabling infrastructure
meets the necessary network specifications. Because of the HP
Auto-MDIX feature, for connections to end nodes (computers,
servers, printers and other peripherals), or connections to hubs
or other switches, you can use straight-through cables. Crossover
cables can also be used for any of these connections. See the
following table for cable types and lengths, and see appendix B,
“Cables and Connectors” for more information:
Table 2-1. Summary of Cable Types to Use with the Switch
■Installation Location - Before installing the switch, plan its
location and orientation relative to other devices and equipment.
At the front of the switch, leave at least 7.6 cm (3 inches) of space
for the twisted-pair cabling. At the back of the switch, leave at
least 2.6 cm (1 inch) of space for the adapter’s power cord.

Installation Procedures
2. Verify the Switch Passes Its Self Test
Before mounting the switch in its network location, you should first
check that it is working properly by plugging it into a power source
and verifying that it passes its self test.
1. Connect the adapter’s power cord to the power connector on the
back of the switch, and then plug the AC power adapter into a
nearby properly grounded electrical outlet.
2. Check the LEDs on the switch. The LED behavior is described on
the next page.
Note The Switch 408 does not have a power switch. It is powered
on when the AC power adapter is connected to the switch
and to a power source.
Caution Use only the AC power adapter supplied with the switch.
Use of other adapters, including those that came with other
HP network products, may result in damage to the equip-
ment.
