Mode LED View Button and Indicator LEDs
To optimize the amount of information that can be displayed for each of the
switch ports, the Series 2700 Switches use a Mode LED for each port. The
operation of this LED is controlled by the Mode LED View button, and the
current setting is indicated by the Mode indicator LEDs near the button. Press
the button to change 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 Speed (Spd) indicator LED is lit, the Mode LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• Flashing = 100 Mbps (the flashing behavior is a repeated 1.6 sec. cycle
of two quick flashes followed by an off period)
• On = 1000 Mbps

Features
The features of the Series 2700 Switches include:
■8 or 24 auto-sensing 10/100/1000Base-T RJ-45 ports.
■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 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.
Complying with the IEEE 802.3ab standard, 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 hardware addresses in each switch’s address
forwarding table (the Switch 2708 has an 8000-entry table, the Switch 2724
has a 32,000-entry table).
■automatically negotiated full-duplex operation for the twisted-pair ports
when connected to other auto-negotiating devices.
■auto-negotiation of flow control for ports operating at full duplex.

Switch Operation Overview
Introducing the HP Procurve
Series 2700 Switches
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 Series 2700 Switch’s 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 Series 2700 Switch 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 Series 2700 Switch
automatically recognizes the change and updates the address table with the
new port location of the device. Communication with the device is automati-
cally maintained, without any address table manipulation being required.

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 that the physical environment
into which you will be installing the switch is properly prepared including
having the correct network cabling ready to connect to the switch, and
having a good location for the switch. 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 2-6.
3. Mount the switch. The Series 2700 Switches can be mounted in a 19-inch
telco rack or equipment cabinet, on a wall, or on a horizontal surface.
4. Connect power to the switch. Once the switch is mounted, plug it in to
the nearby AC power source.
5. Connect the network devices. Using the appropriate network cables,
connect servers, hubs, other switches, routers, 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
Installing the Series 2700
Switches
Installation Precautions:
Follow these precautions when installing your HP Series 2700 Switches.
Warnings ■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.
■For safe operation, do not install the switch with the back face of the
switch (with the fan vents) facing either downward or upward.
Cautions ■Make sure that the power source circuits are properly grounded, then
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 the cord is adequately sized for the switch’s
current requirements. In addition, 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, note that the AC outlet should be near the
switch and should be easily accessible in case the switch must 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.

Installation Procedures
Installing the Series 2700
Switches
1. Prepare the Installation Site
■Cabling Infrastructure - Ensure that the cabling infrastructure meets
the necessary network specifications. See the following table for cable
types and lengths, and see appendix B, “Switch Ports and Network
Cables” 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 7.6 cm (3 inches) of space for
the power cord and cooling.
• On the sides of the switch, leave at least 3.8 cm (1 1/2 inches) for
cooling.
Cable Type Length Limits
• 10 Mbps operation:
Category 3, 4, or 5, 100-ohm differential
unshielded twisted-pair (UTP) or shielded
twisted-pair (STP)
• 100 Mbps operation:
Category 5, 100-ohm differential UTP or
STP
• 1000 Mbps operation:
Category 5E or better, 100-ohm differen-
tial UTP or STP
100 meters
100 meters
100 meters
Notes: Since the 10Base-T operation is through 10/100/1000Base-T ports, if you ever want
to upgrade the ports to 100Base-TX, it would be best to cable the ports initially with category
5 cable. For 1000Base-T, category 5E, or better, cable should be used.
The 10/100/1000-Base-T ports on the Switch 2708 include the IEEE 802.3ab
“Auto MDI/MDI-X” feature. This feature allows you to use either straight-through or
crossover twisted-pair cables for connecting to any network devices including end nodes,
such as computers, or to other switches, hubs, and routers.
