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.
Linksys One Portal
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.

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.
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.
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.
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.

units to be logically stacked together. It is recommended that multiple Ethernet switches
be mounted in a rack when installed in this manner. Ethernet switches can be physically
placed at different locations; they do not have to be stacked at the same location.
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.
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 reinstallation.
2. Place one of the supplied spacers on the side of the Ethernet switch so the four holes
align to the screw holes.

Ethernet network cable to one of the uplink ports on the Ethernet switch.
2. Connect the other end to a PC or other network device.
3. Repeat steps 2 and 3 to connect additional devices.
4. If you are using the mini-GBIC port, then insert the mini-GBIC module to the mini-GBIC
port. For detailed instructions, refer to the documentation supplied with the mini-GBIC
module.
CAUTION: Observe the orientation of
the mini-GBIC module before inserting it
into a mini-GBIC port. The bottom miniGBIC ports are upside down in relation
to the top mini-GBIC ports.
5. If you use the console interface to configure the Ethernet switch, then connect the
supplied serial cable to the console port (located on the back of the Ethernet switch), and
tighten the captive retaining screws. Connect the other end to your PC’s serial port. (The
PC must be running VT100 terminal emulation software, such as HyperTerminal.)
NOTE: If connecting an Ethernet switch
to an SVR3000 router, connect it to a
Cascade port on the SVR3000.
6. Connect the supplied power cord to the power port, and plug the other end into an
electrical outlet.
CAUTION: Make sure you use the
power cord that is supplied with the
Ethernet switch. Use of a different
power cord could damage the Ethernet
switch.
7. Power on the network devices connected to the Ethernet switch. Each active port’s
corresponding Act/Link LED will light up on the Ethernet switch. If a port has an active
