Introduction
Welcome
Thank you for choosing a Linksys Ethernet switch. This Ethernet switch allows you to quickly
and easily expand your Linksys One system. It delivers non-blocking, wire speed switching
for your network clients, plus multiple options for connecting to your network backbone.
Twenty four ports wire up your workstations or connect to other Linksys switches or devices.
LED indicators provide power, link, and activity status.
The Ethernet switch features monitoring and configuration via the Linksys One Portal, your
web browser, or the console interface. If your Ethernet switch is part of a Linksys One system,
the easiest way to manage it is with the Linksys One Portal — available only on the Linksys
One Services Router. Refer to the Linksys One Customer Premises Equipment Administration
Guide for more details on the Linksys One Portal.
The Ethernet switch supports numerous security features including the Remote Authorization
and Authentication (RADIUS) and Terminal Access Controller Access Control System
(TACACS+) protocols. With Simple Network Time Protocol (SNTP), the Ethernet switch can
synchronize its clock with a time server available on one of its attached networks.
The system is fully manageable using a combination of a database of MIB (Management
Information Base) variables, whose combined values represent all facets of the system state,
and the Simple Network Management Protocol (SNMP) protocol.
The “P” model of the Ethernet switch supports Power over Ethernet (PoE) which eliminates the
need to run 110/220 VAC power to wireless network, IP telephony, or other PoE powered
devices on the Linksys network. Use of a PoE system allows greater flexibility in locations of
network devices, and significantly decreasing installation costs. The entire PoE system can be
centrally powered by uninterruptible power supplies if necessary.
What’s in this User Guide?
This user guide covers the steps for setting up and using the Ethernet switch. Use the
instructions in this guide to help you connect the switch, set it up, and configure it to your
Linksys network. These instructions should be all you need to get the most out of your
Ethernet switch.

Getting to Know the Switch
Overview
The SGE2000 and SGE2000P models are 24-port, layer-2 Ethernet switches that expand
the capability of the Linksys system. These two versions are functionally identical except the
SGE2000P model offers Power-over-Ethernet (PoE) which can be used to supply power to
various Linksys products over Ethernet cable.
The Front Panel
The Switch's LEDs and Ethernet ports are located on the front panel.
Front Panel LEDs
The Switch uses Light Emitting Diodes (LEDs) to indicate the status of numerous functions.
These functions are listed below.

1
System Status LEDs. Four LEDs indicate the status
of the Ethernet switch power, fan, RPS connectivity,
and stack master. For more details, refer to
”System Status LEDs,” on page 4.
2
LAN Ports. Twenty four 10/100/1000 BaseT LAN
ports provide connectivity to other Linksys devices.
For more details, refer to ”LAN Ports,” on
page 5.
3
Gigabit Interface Converter (mini-GBIC) Uplink
Ports. Four mini-GBIC ports provide uplink ports
which support network speeds of 10Mbps,
100Mbps, and 1000Mbps. For more details, refer
to ”Uplink Ports,” on page 6.
4
Stack ID. If stacking is active, indicates the ID
number of the stack. For more details, refer to
”Stack ID LEDs,” on page 4.
5
RESET Switch. Resets the SGE2000/SGE2000P
Ethernet switch. For more details, refer to ”Reset
Switch,” on page 5.

Stack ID LEDs
PWR A green PWR LED lights to indicate that the Ethernet switch is powered
by internal power supplies. If the Ethernet switch is powered by a
remote power supply (RPS), this LED blinks red.
FAN A green FAN LED lights to indicate that the cooling fan is operating
properly. A blinking red FAN LED indicates that the cooling fan has
failed.
RPS A green RPS LED lights to indicate that RPS is connected and operating
properly. A blinking red RPS LED indicates an RPS fault.
MST A green MST LED indicates that this Ethernet switch is a stack master.
Act/Link The green Act/Link LEDs light to indicate a functional network link
through the corresponding port with an attached device. The Act
(Activity) LEDs flash to indicate that the Ethernet switch is actively
sending or receiving data over that port.
Act/Link The green Act/Link LEDs light to indicate a functional network link
through the corresponding port with an attached device. The Act
(Activity) LEDs flash to indicate that the Ethernet switch is actively
sending or receiving data over that port.
Gigabit The Gigabit LED lights indicate a Gigabit connection on the
corresponding port.
Stack ID A green Stack ID LED indicates that this Switch is stacked and the
corresponding number indicates its stack ID. Range is 1 to 8.

Reset Switch
The Ethernet switch can be reset by inserting a pin or paper clip into the RESET opening. If
the reset switch is held for 10 seconds or longer, the Ethernet switch will be reset to its default
settings.
When a unit is reset to its default setting, the unit restarts in stackable mode using default
stacking ports with autonumbering enabled. Pressing the reset button on the master unit of a
stack resets all units in the stack.
LAN Ports
The Ethernet switch is equipped with 24 Ethernet ports.
CAUTION: All user-defined settings are
lost when you hold the Reset button for
10 seconds or longer; the Ethernet
switch reverts to its default settings.
1-24 The Switch is equipped with 24 auto-sensing, Ethernet (IEEE 802.3)
network ports, which use RJ-45 connectors. The Gigabit Ethernet ports
support network speeds of 10Mbps, 100Mbps, and 1000Mbps. They
can operate in half and full-duplex modes. Auto-sensing technology
enables each port to automatically detect the speed of the device
connected to it, and adjust its speed and duplex accordingly.
In stacking mode, two ports are used for stacking. By default, the
stacking ports are 12 and 24.
Ports 11, 12, 23, and 24 are shared with GBIC1, GBIC3, GBIC2,
GBIC4 respectively. If shared port pairs are both connected, then the
mini-GBIC port takes priority.
