Introducing the E3800 Switches
The HP E3800 switches are multiport switches that can be used to build highperformance switched networks. These switches are store-and-forward
devices offering low latency for high-speed networking. The E3800 switches
also support a field-replaceable Redundant Power Supply and fan tray, Power
over Ethernet (PoE/PoE+) technologies, and full network management
capabilities.
In addition, the E3800 switches support the HP FlexChassis Mesh feature
for stacking the switches. When E3800 Stacking Modules (J9577A) are
installed in the switches, any combination of up to ten E3800 switches can be
stacked together via high-speed backplane cables to form a single extended
virtual switch. See “Stacking Information and Topologies” on page 2-23, and
the E3800 Advanced Traffic Management Guide for more stacking
information.
These switches are described in this manual:

Stacking
Notes:
■ For E3800 switches that are in a stack, the Mode select button on every
switch in the stack controls the LED mode for all the switches in the stack.
■ If there is a combination of PoE/PoE+ switches and non-PoE switches in
the stack, when any of the Mode select buttons is pressed to put the stack
into PoE mode, the non-PoE switches indicate no PoE support by not
illuminating any of the Mode indicator LEDs or any of the port LEDs.
■ If any of the switches in the stack are configured with the Save Power
LED feature, then the default LED Mode for the whole stack becomes the
Save Power display (all LED Mode indicator LEDs are off), but only the
stack members on which that feature is configured display the other
characteristics of that feature (all LEDs Off except for the Power LED).

Power Supplies
There are two power supplies that can be installed into the E3800 switches:
■ HP X311 400W 100-240VAC to 12VDC PS (J9581A) -- a 400 watt power
supply for the Non-PoE switches. The 400 watt power supply does not
provide any PoE power. The 400 watt power supply is keyed such that it
will not fit into the PoE+ switches.
■ HP X312 1000W 100-240VAC to 54VDC PS (J9580A) -- a 1000/700 watt
power supply for the PoE+ switches. The 1000/700 watt power supply
provides PoE/PoE+ power. The 1000/700 watt power supply is keyed such
that it will not fit into the Non-PoE switches. When supplied with 110 V,
the power supply runs at a max of 700 W and when supplied with 220 V,
the power supply runs at a max of 1000 W.
For more power supply information see page 2-17.
Power Connector
The E3800 switches do not have a power switch; they are powered on when
connected to an active AC power source. These switches automatically adjust
to any voltage between 100-127 or 200-240 volts and either 50 or 60 Hz. There
are no voltage range settings required.
Module Slot
Each of the E3800 switches has one module slot that can accept the HP E3800
Stacking Module that provides high-speed connectivity to other E3800
switches. Only the E3800 switches support this module.

Fan Tray
The E3800 switches have a field-replaceable fan tray. If necessary, the fan can
be replaced while the switch is operating. For more information, see
“Replacing the Fan Tray” on page 4-2.
HP E3800 Stacking Module
The HP E3800 4-port Stacking Module (J9577A) is a component you can add
to an HP E3800 Switch to provide high-speed stacking connections to other
E3800 switches. See “Stacking Information and Topologies” on page 2-23, and
the E3800 Advanced Traffic Management Guide for more information about
stacking configuration and operation.

Switch Features
The features of the E3800 Switches include:
■ Combinations of fixed 10/100/1000-T and 10-Gigabit ports, and SFP/SFP+
■ Selected switch models feature XG ports that are compliant with IEEE
■ One module slot is provided in the back of the switches to support a

the appendices for cabling recommendations and requirements.
stacking module to provide connectivity to other E3800 switches with
stacking modules. See “Stacking Information and Topologies” on page 2-
23, the E3800 Advanced Traffic Management Guide for more
information about stacking.
E3800-48G-4SFP+-PoE+ switches are IEEE 802.3at standard compliant
and provide up to 30 W per port to power IP phones, wireless access
points, web cameras, and more. For more information, see the HP Power
over Ethernet (PoE/PoE+) Planning and Implementation Guide which
is on the HP Web site, www.hp.com/networking/support.
1-18
The switches support 802.3af and 802.3at standard devices and some prestandard PoE devices. For a list of these devices, see the FAQs (Frequently
Asked Questions) for your switch model. PoE is disabled by default and
must be enable for use. (For instructions, see the Management and
Configuration Guide for your switch at
www.hp.com/networking/support.
■ The option to have one or two internal power supplies.
A second power supply may support redundant power or additional PoE+
power. If one of the internal power supplies fails, the second power supply
will immediately provide power necessary to keep the switch running,
including PoE+ power on an allocated basis.
If maximum PoE+ power is being used on the 48 port PoE+ switch, the
second power supply is needed for PoE+ power and in this case there is
no PoE power redundancy, however system power will always be maintained. On a power supply failure, the system will drop PoE power on
ports based on user priority, to maintain system power. For more information on the power supplies see page 1-15
■ Plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.

meaning that all connections can be made using straight-through
twisted-pair cables. Cross-over cables are not required, although they
will also work. 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. (See the appendices for recommended or required cabling.)
■ Automatic learning of the network addresses in each switch’s 8000-
address forwarding table, (with configurable address aging value).
■ Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45
ports when connected to other auto-negotiating devices—the SFP/SFP+
ports always operate at full duplex.
■ Easy management of the switch through several available interfaces:
• console interface—a full featured, easy to use, VT-100 terminal
interface for out-of-band switch management (through the console
port or Management network ports) or in-band Telnet access to the
switch.
• Web browser interface—an easy to use built-in graphical interface
that can be accessed from common web browsers.
• HP Professional Management Center (PMC)—an SNMP-based,
graphical network management tool that you can use to manage your
entire network. This product is included with your new switch.
■ Support for the Spanning Tree Protocol to eliminate network loops.
■ Support for up to 2048 IEEE 802.1Q-compliant VLANs so you can divide
the attached end nodes into logical groupings that fit your business needs.
■ Support for many advanced features to enhance network performance—
for a description, see the E3800 Management and Configuration Guide
at www.hp.com/networking/support.
■ Ability to update the switch software. Software updates are routinely
available from HP.
■ An auxiliary port (USB Type A connector) for processing a USB command
file and updating switch software.
■ Low power operation:
• Ports on a switch or stack member may be set to operate at reduced
power.
• Port status LEDs may be turned off.
RJ-45 ports will operate at reduced power if the port is not connected (link
partner is not detected).

Installation Procedures
Summary
1. Prepare the installation site (page 2-5). Ensure the physical environment is properly prepared, including having the correct network cabling
ready to connect to the switch and having an appropriate location for the
switch. See page 2-4 for some installation precautions.
Note For steps 2 and 3 below, if an E3800 switch is powered on for the first time
without a stacking module installed, stacking will be disabled and that will be
saved in the switch's running configuration. For more information, see
“Stacking Information and Topologies” on page 2-23.
2. Verify the switch passes self test (page 2-6). Plug the switch into a
power source and observe that the LEDs on the switch’s front panel
indicate correct switch operation. When self test is complete, unplug the
switch.
