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.

8Introducing the 3Com Unified Gigabit Wireless PoE Switch 24

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.

10 AC Power Input: Accepts 100–240 Vac, 50/60 Hz input power. The switch automatically adjusts to

the input voltage.

11 Feet: These are self-adhesive pads. You do not need to install them if you are rack-mounting the

switch.

WARNING: The Network Ports are shielded RJ-45 data sockets. They

cannot be used as standard traditional telephone sockets, or to connect

the unit to a traditional PBX or public telephone network. Connect only

RJ-45 data connectors, network telephony systems, or network

telephones to these sockets.

Either shielded or unshielded data cables with shielded or unshielded

jacks can be connected to these data sockets.

AVERTISSEMENT: Points d’accès RJ-45. Ceux-ci sont protégés par des

prises de données. Ils ne peuvent pas être utilisés comme prises de

téléphone conventionnelles standard, ni pour la connection de l’unité à

un réseau téléphonique central privé ou public. Raccorder seulement

connecteurs de données RJ-45, systèmes de réseaux de téléphonie ou

téléphones de réseaux à ces prises.

Il est possible de raccorder des câbles protégés ou non protégés avec des

jacks protégés ou non protégés à ces prises de données.

WARNHINWEIS: RJ-45-Porte. Diese Porte sind geschützte

Datensteckdosen. Sie dürfen weder wie normale traditionelle

Telefonsteckdosen noch für die Verbindung der Einheit mit einem

traditionellem privatem oder öffentlichem Telefonnetzwerk gebraucht

werden. Nur RJ-45-Datenanscluße, Telefonnetzsysteme or Netztelefone

an diese Steckdosen anschließen.

Entweder geschützte oder ungeschützte Buchsen dürfen an diese

Datensteckdosen angeschlossen werden.

Overview of the

Unified Gigabit

Wireless PoE

Switch 24

The 3Com® Unified Gigabit Wireless PoE Switch 24 is a versatile,

easy-to-use unified switch. It is shipped ready for use, and no

configuration is necessary for operation as a basic Layer 2 Gigabit PoE

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

(PoE) Features

The switch can provide Power over Ethernet (PoE) to 802.3af compliant

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
