Introduction
Welcome
Thank you for choosing a Linksys Switch. This Switch will allow you to quickly and economically
expand your Linksys system.
This new Linksys rack mount Switch delivers non-blocking, wire speed switching for your
network clients, plus multiple options for connecting to your network backbone. Forty eight
ports wire up your workstations or connect to other Linksys switches or devices.
The Switch features monitoring and configuration via your web browser, making it easy to
manage your Switch. Or if you prefer, you can use the console interface to configure the Switch.
Use the instructions in this guide to help you connect the switch, set it up, and configure it to
bridge your different networks. These instructions should be all you need to get the most out of
the Switch.

Getting to Know the SFE2010/SFE2010P
This chapter describes the ports, LEDs, and other features on the front and back panels of the
switch.
The SFE2010 and SFE2010P are 48-port, layer-2 Ethernet switches that affordably expand the
capability of the Linksys system. These two versions are functionally identical except the
SFE2010P model offers Power-over-Ethernet (PoE) which can be used to supply power to
various Linksys products over Ethernet cable.
SFE2010/P Front Panel
Feature Description
Reset The Switch can be reset by inserting a pin or paper clip into the RESET
opening.
CAUTION: If the RESET switch is pressed for more than 10 seconds, the
Switch will reset to its default settings. All customized user settings will be
lost.
LEDs The Switch uses Light Emitting Diodes (LEDs) to indicate the status of
numerous functions. These functions are listed below.
PWR A green PWR LED lights up to indicate that the Switch is powered on.
FAN A green FAN LED lights up 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 up 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 Switch is a stack master.
Stack ID A green Stack ID LED indicates that this Switch is stacked and the
corresponding number indicates its stack ID.
Act/Link The green Act/Link LEDs light up to indicate a functional network link
through the corresponding port with an attached device. The Act
(Activity) LEDs flash to indicate that the Switch is actively sending or
receiving data over that port.
Speed On the SFE2010, a green Speed LED indicates that the port is linked to a
100Mbps device.
PoE On the SFE2010P, a green PoE LED indicates that PoE is active on that port.
Gigabit The Gigabit LED lights up to indicate a Gigabit connection on the
corresponding port.

Getting to Know the SFE2010/SFE2010P
1-48 The Switch is equipped with 48 auto-sensing, Ethernet (802.3) network
ports, which use RJ-45 connectors. The Fast Ethernet ports support
network speeds of 10Mbps or 100Mbps. 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.
The switch can deliver a maximum of 15.4W to a PoE port. With regular AC
power supply, there is 360W available to all PoE ports, and 280W available
with redundant power supply.
G1-G2 Ports G1-G2 are Ethernet (802.3ab) uplink ports which support network
speeds of 10Mbps, 100Mbps, and 1000Mbps.
NOTE: A switch is in stacking mode by default. In stacking mode, ports G1
and G2 are reserved for use as stacking ports.
miniGBIC1/2 The Switch provides two mini-GBIC ports. The mini-GBIC (gigabit interface
converter) port is a connection point for a mini-GBIC expansion module,
so the Switch can be uplinked via fiber to another switch. Each mini-GBIC
port provides a link to a high-speed network segment or individual
workstation at speeds of up to 1000Mbps.
Use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules with the
Switch. The MGBSX1 and the MGBLH1 require fiber cabling with LC
connectors, while the MGBT1 requires a Category 5e Ethernet cable with
an RJ-45 connector.

Sample Network Configuration
For an example of a possible network configuration, see the application diagrams shown
below.
Maximum Cabling Distances
When you connect your network devices, make sure you don’t exceed the maximum cabling
distances, which are listed in the following table:
*A hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A
10Mbps hub connected to another 10Mbps hub can span up to 100 meters (328 feet).
From To Maximum Distance
Switch Switch or Hub* 100 meters (328 feet)
Hub Hub 5 meters (16.4 feet)
Switch or Hub Computer 100 meters (328 feet)

Connecting Devices
Before You Install the Switch...
When you choose a location for the switch, observe the following guidelines:
• Make sure that the switch will be accessible and that the cables can be easily connected.
• Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting
fixtures.
• Position the switch away from water and moisture sources.
• To ensure adequate air flow around the switch, be sure to provide a minimum clearance of
two inches (50 mm).
• Connect the supplied power cord to the switch’s power port, and plug the other end into an
electrical outlet.
CAUTION: Make sure you use the power cord that is supplied with the switch. Use of a
different power cord could damage the switch.
Placement Options
Before connecting cables to the Ethernet switch, first you will physically install the Ethernet
switch. Either set the Ethernet switch on its four rubber feet for desktop placement, mount it in
a standard-sized, 19-inch wide for rack-mount placement, or mount it on a wall with the wall-
mount brackets provided.
NOTE: The four supplied mounting brackets can be used for either wall mount or rack
mount installations.
Desktop Placement
1. Attach the rubber feet to the recessed areas on the bottom of the Ethernet switch.
2. Place the Ethernet switch on a desktop near an AC power source.

Placement Options
Connecting Devices
CAUTION: Keep enough ventilation space for the Ethernet switch so it does not exceed the
environmental restrictions mentioned in the specifications.
Rack-Mount Placement
To mount the Ethernet switch in any standard-sized, 19-inch wide, (each Ethernet switch
requires 1RU of space in the rack), follow these instructions:
1. Remove the four front screws on one side of the Ethernet switch. Retain the screws for re-
installation.
2. Place one of the supplied spacers on the side of the Ethernet switch so the four holes align
to the screw holes.
3. Place a rack mount bracket next to the spacer and reinstall the four screws (removed in step
1).
4. Repeat steps 2 through 3 for the other side of the Ethernet switch.
5. Attach the Ethernet switch to the rack using the supplied screws.
