Linksys One Ready Communications Solution
1 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. Linksys One Portal 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.

|
|
|
|
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.
Chapter 3: Connecting the Switch |

Placement Options |
|
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.
Wall-Mount Placement
1.On one of the side corners, remove the four front screws on of the Ethernet switch. Retain the screws for re-installation.
NOTE: The Ethernet switch, shown below, is mounted with the ports located on top. When the switch is mounted to a wall, the ports can be oriented in any direction.
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). The wall mount brackets should point towards the bottom of the Ethernet switch.
4.Repeat steps 1 through 3 for the other corners of the Ethernet switch.
5.Attach the Ethernet switch to a wall with appropriate screws (not supplied).
CAUTION: Ensure that the Ethernet switch is securely attached to the wall.

|
|
into a mini-GBIC port. The bottom mini- |
|
|
|
|
GBIC ports are upside down in relation |
|
|
|
|
to the top mini-GBIC ports. |
|
|
|
|
|
|
|
