Table 1 Features of the Unified Switch 24
Reference Description
110/100/1000 Mbps Network Ports (1–24): These autonegotiating ports determine the speed and duplex mode based on the connected device. Each port supports automatic MDI/MDIX detection and can be connected to a 10BASE-T, 100BASE-T, or 1000BASE-T device.
2LED Port Status Indicators: Each Network Port has a corresponding status indicator (1 to 24) that shows the status of the port’s network connection or PoE status (depending on the LED Status Select button).
Port Speed
■Green steady: 1000 Mbps link is present.
■Green flashing: 1000 Mbps traffic is present.
■Amber steady: 10/100 Mbps link is present.
■Amber flashing: 10/100 Mbps traffic is present.
■Off: Link is not present
PoE Status
■Green steady: PoE Power is being delivered to the port
■Off: No power is being delivered.

Table 1 Features of the Unified Switch 24 (continued)
Reference Description
3LED Status Select Button: This button sets the function of the Port LED indicators. When the button is in the out position, the port LEDs show the port speed (see #2 above). When the button is pressed in, the port LEDs show the PoE status.
4SFP Module Slots (21–24): The four Small Form Factor Pluggable (SFP) transceiver slots allow you to install an SFP transceiver (purchased separately). These ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in any combination.
When an SFP module is installed in a slot and is active, the associated RJ-45 port (21 to 24) of the same number is disabled.
5SFP Module Status Indicator: The four SFP status LED indicators show the state of the SFP module ports (21 to 24; see #4).
■Green: An SFP fiber module is present.
■Off: No fiber module is present.
When an SFP module is present, the fiber port activity is indicated by the corresponding LED over the RJ-45 port (21 to 24):
■Green steady: Fiber link is present.
■Green flashing: Fiber link traffic is present.
■Off: Link is not present
6Fan Indicator: Shows the status of the internal fans. Green steady: All fans are functioning properly. Amber steady: The switch is too hot.
Amber flashing: One or more fans have failed
7System Indicator: Shows the overall status of the switch.
■Green steady: The switch is powered-up and operating normally.
■Green flashing: The switch is undergoing self test, initialization, or downloading.
■Amber steady: The switch has detected a hardware malfunction such as temperature, fan, or voltage.
■Off: No power. The switch is off.
8Console Port: Allows you to connect a terminal and perform out-of-band management. The default communications settings are 19200 bps, 8 data bits, no Parity, 1 stop bit.
9Reset Button: Use the reset button to restore the switch to its factory defaults. See “Restoring the Factory Default Settings” on page 29.
10AC Power Input: Accepts 100–240 Vac, 50/60 Hz input power. The switch automatically adjusts to the input voltage.
11Feet: These are self-adhesive pads. You do not need to install them if you are rack-mounting the switch.

Overview of the |
The 3Com® Unified Gigabit Wireless PoE Switch 24 is a versatile, |
Unified Gigabit |
easy-to-use unified switch. It is shipped ready for use, and no |
Wireless PoE |
configuration is necessary for operation as a basic Layer 2 Gigabit PoE |
Switch 24 |
switch. Additional features such as wireless can be configured easily using |
|
the Web-based user interface and setup wizard. Support for PoE and |
|
voice auto-prioritization makes the Unified Switch 24 a perfect starting |
|
point for IP telephony solutions. |
Unified Switching |
A unified switch is an all-in-one, fully-managed Ethernet switch |
|
combining gigabit, wireless, and PoE connectivity in a single platform. |
|
The Unified Switch 24 supports both wired Ethernet switching and |
|
centralized control for up to 24 wireless access points. |
10 Introducing the 3Com Unified Gigabit Wireless PoE Switch 24
Wired Features The switch has 24 shielded RJ-45, 10/100/1000 Mbps auto-negotiating ports and four Small Form Factor Pluggable (SFP) transceiver slots on the front panel.
The four SFP ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the switch and a 1000 Mbps core network.
When an SFP port is in operation, the corresponding 10/100/1000BASE-T port (21 to 24) is disabled.
Power over Ethernet The switch can provide Power over Ethernet (PoE) to 802.3af compliant (PoE) Features devices over a Category 5 or better Ethernet cable. The switch can supply
up to 15.4 Watts of PoE to each of the 24 gigabit ports simultaneously. PoE (802.3af) is a self-configuring protocol. When you plug an 802.3af device into one of the gigabit ports on the switch, the switch will supply the required power to the device.
Wireless Features The 3Com Unified Switch 24 provides centralized control for up to 24 3Com 7760 or 8760 Access Points. Key wireless features include:
■Enterprise-grade WPA2/AES encryption
■802.1X authentication
■Centralized control for wireless security profiles
■Fast roaming
■Rogue AP detection and mitigation
■Multiple SSIDs per radio
■Traffic prioritization
■Load balancing

Installing the 3Com Unified |
Switch 24 |
Checking the
Package Contents
The Unified Switch 24 package includes the following items:
■One 3Com Unified Gigabit Wireless PoE Switch 24 unit
■One power cord
■Four standard height, self-adhesive rubber pads
■One mounting kit
■One warranty flyer and one safety flyer
■This Quick Start Guide
If any of the above items are damaged or missing, please contact your network supplier immediately.
WARNING: Before installing this switch, please read the safety flyer included with the unit.
GEFAHR: Lesen Sie bitte vor Installation des Switch das diesem Gerät beiliegende Sicherheitsblatt durch.
Choosing a Suitable The switch can be free-standing (see “Free-Standing Installation” on Location page 12), or it can be mounted in a 19-inch equipment rack using the
supplied mounting kit (see “Rack-Mount Installation” on page 13). When deciding where to position the switch, ensure that:
■It is accessible and cables can be connected easily.
■Cabling is away from sources of electrical noise. These include elevator shafts, microwave ovens, and air-conditioning units. Electromagnetic fields can interfere with the signals on copper cabling and introduce errors, and, consequently, slow down your network.
■Water or moisture cannot enter the case of the unit.
12Installing the 3Com Unified Switch 24
■Air flow around the unit and through the vents on the side of the case is not restricted. 3Com recommends that you provide a minimum of 25 mm (1 in.) clearance.
■The air is as free of dust as possible.
■Temperature operating limits are not likely to be exceeded. 3Com recommends that you install the switch in a clean, air conditioned environment.
When installing network equipment, it is always good practice to wear an antistatic wrist strap that is connected to a ground point. If one is not available, try to keep in contact with a grounded rack and avoid touching the unit's ports and connectors. Static discharge can cause reliability problems in your equipment.
Aufstellen des |
Bei der Entscheidung wo Sie den Switch positionieren, stellen Sie sicher |
Switch |
das: |
|
■ Der Switch zugänglich ist und die Kabel leicht angeschlossen werden |
|
können. |
|
■ Die Kabel nicht in der nähe von elektrischen Störquellen befinden. Das |
|
schließt Aufzugsschächte, Mikrowellen und Klimaanlagen ein. |
|
Elektromagnetische Felder können die Signale in den Kupferleitungen |
|
stören, und Fehler verursachen, was die Verlangsamung Ihres |
|
Netzwerkes zur Folge haben kann. |
|
■ Weder Wasser noch Feuchtigkeit in das Gehäuse eindringen kann. |
|
■ Die Luftzirkulation um den Switch und durch die Öffnungen des |
|
Gehäuses nicht behindert wird. 3Com empfiehlt das Sie 25mm (1 |
|
Inch) Zwischenraum sicherstellen. |
|
■ Die Luft so frei wie möglich von Staub ist. |
|
■ Es unwahrscheinlich ist das die Betriebstemperatur überschritten wird. |
|
3Com empfiehlt das Sie den Switch in einer sauberen, klimatisierten |
|
Umgebung installieren. |
|
|
Free-Standing |
Place the switch on a stable, flat surface where it is not likely to be |
Installation |
disturbed. Do not place objects on top of the switch or on top of a stack |
|
of switches. When locating the unit, you should take note of the |
|
guidelines given in “Choosing a Suitable Location” on page 11. |
