Introducing the E3800 Switches
The HP E3800 switches are multiport switches that can be used to build high-
performance 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:

Notes:
1All RJ-45 ports support “Auto-MDIX”, which means you can use either straight-through or crossover twisted-pair cables
to connect network devices to the switch.
2SFP ports support 1G SFP transceivers. J9584A SFP ports also support 100 Mb (100-FX and 100-BX) transceivers.
3 SFP+ ports support 1G SFP and 10G SFP+ transceivers.

Management Ports
Console Port
This port is used to connect a console to the switch by using the serial cable
supplied with the switch. This connection is described under “9. (Optional)
Connect a Management console” on page 2-18 in chapter 2, “Installing the
Switch.” The console can be a PC or workstation running a VT-100 terminal
emulator, or a VT-100 terminal.

Out-of-Band Management (OOBM) Port
This RJ-45 port is used to connect a dedicated management network to the
switch.
Auxiliary (Aux) Port
An auxiliary port for processing a USB command file or downloading switch
software code. This port uses a USB Type A connector, but does not comply
with USB protocols and standards.
Switch and Port LEDs
■Table 1-3 describes the switch and port LEDs and their operation for
standalone E3800 switches.
■Table 1-4 describes the operation of the LEDs when the switches are
stacked. It includes descriptions of all stacking-related LEDs including
those for Module Status and Stacking Status.
Table 1-3. Standalone Switch and Port LED Behavior
Switch LEDs State Meaning
Power
(green)
On
Off
The switch is receiving power.
The switch is NOT receiving power.
Fault
(orange)
Off The normal state; indicates there are no fault conditions on the switch.
Blink
orange*
A fault has occurred on the switch, one of the switch ports, module in the rear of the
switch, or the fan. The Status LED for the component with the fault will blink
simultaneously.
On On briefly after the switch is powered on or reset, at the beginning of switch self test.
If this LED is on for a prolonged time, the switch has encountered a fatal hardware
failure, or has failed its self test. See chapter 4, “Troubleshooting” for more information.
Locator
(blue)
On
Blinking
Off
The Locator LED is used to help you identify a specific in your network equipment
installation. The LED can be set to be on solid or to blink, and for a specified number of
minutes (1-1440). The default is 30 minutes. Use the command “chassislocate” to
control this LED.

1-9
Introducing the E3800 Switches
Fronts of the Switches
Test
(green/
orange)
Off The normal operational state; the switch is not undergoing self test.
On The switch self test and initialization are in progress after the switch has been power
cycled or reset. The switch is not operational until this LED goes off. The Self Test LED
also comes on briefly when you “hot swap” a mini-GBIC into the switch; the mini-GBIC
is self tested when it is hot swapped.
Blink
orange*
A component of the switch has failed its self test. The status LED for that component,
for example the Fan LED, and the switch Fault LED will blink simultaneously.
Port LEDs
(green/
orange-Link
and Mode)
Link For non-PoE or PoE-disabled ports:
Displays port link information:
• On – The port is enabled and receiving a link indication from the connected device.
• Off – The port has no active network cable connected, or is not receiving link beat
or sufficient light (fiber-optic port). Otherwise, the port may have been disabled
through the switch console, the web browser interface, or network management.
• Blinking orange*– The corresponding port has failed its self test. Blinks simultane-
ously with the switch Fault LED.
For PoE-enabled ports, see the LED mode information for PoE mode below.
Mode The operation of the port Mode LED is controlled by the LED Mode select button, and
the current setting is indicated by the LED Mode indicator LEDs near the button. Press
the button to step from one view mode to the next. The default view is Activity (Act).
If the Save Power LED feature has been enabled on the switch (savepower led
command), then that becomes the default view - all port LEDs are Off when the switch
is operating according to that feature.
Switch LEDs State Meaning

Introducing the E3800 Switches
Fronts of the Switches
LED Mode
View (green)
Act Indicates the port LEDs are displaying network activity information.
FDx Indicates port Mode LEDs are lit for ports in Full Duplex Mode. Off indicates half duplex.
Spd Indicates the port Mode LEDs are displaying the connection speed at which each port
is operating. Each port Mode LED then indicates one of the following:
• Off – the port is operating at 10 Mbps.
• Blinking** – the port is operating at 100 Mbps.
• On – the port is operating at 1000 Mbps.
PoE‡Indicates that the port Link and Mode LEDs are displaying PoE information as follows:
• Link On – PoE is enabled on the port.
• Link Off – PoE is disabled on the port.
• Link Blink orange** – the port has an error or the port is denied power due to
insufficient power.
• Mode On – the port is providing PoE power.
• Mode Off – the port is not providing PoE power.
Usr When stacking is enabled, this mode is used to display the member ID of the individual
switch via the port Mode LEDs (for member 1, one LED is lit; for member 2, two LEDs
are lit, and so on), and to indicate which switch is the Standby (Cmd LED will blink).
Save Power This mode is indicated by ALL the mode indicator LEDs being Off. This display occurs
only if the switch has been configured with the savepower led command. See the
Management and Configuration Guide for more information on that command.
PS (Power
Supply
Status

A redundant power supply is installed but not connected (the switch Fault LED will not
blink simultaneously). Or, a power supply is connected but has experienced a fault (the
switch Fault LED will be blinking simultaneously).
Power supply is not connected or is not installed.
Fan Status
(green/
orange)
On
Blink
orange*
Normal operation, all fans are OK.
One of the unit’s fans has failed. The switch Fault LED will be blinking simultaneously.
PoE Status

Off†
Blink
orange*
Fast blink
orange**
When the switch is ready to start supplying PoE power.
Should be off only during the boot process.
A port has a internal hardware failure. The switch Fault LED will be blinking
simultaneously.
A port is denied PoE power or is detecting an external PD fault.
