1Power LED Green

Indicates that the Switch is receiving power from the power adapter. If the LED is off there may be a problem with the adapter.

Refer to Problem Solving.

2Status LED Green/Yellow

This LED is used to indicate the status of the system. When this LED is green and not flashing, the system is operating normally. When the switch is booting up and during firmware upgrades the LED will flash green. If the system has failed the Power On Self Test (POST) the LED will illuminate yellow.

3Module Active LED Green

This LED is used to indicate that an SFP module is inserted and is active.

4Eight/ Port Status LEDs

Green (1000 Mbps link) / Yellow (10 or 100Mbps link)

If the LED is on, the link between the port and the next piece of equipment is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected or the connected device is turned off, or there is a problem with the connection (refer to the Problem Solving section).

5Duplex LEDs

Green (10/100/1000 Mbps, full duplex) / Off (10/100 Mbps, half duplex)

6 Power Adapter Socket

Only use the power adapter that is supplied with the Switch.

7 SFP Port

1000BaseLX (3CSFP92) and 1000BaseSX (3CSFP91) transceivers are supported. Use this interface to allow your Switch to connect across distances greater than 100m or where electrical isolation is required. Appropriate multimode fiber cables will also be required (not supplied).

SFP transceivers are hot-insertable and hot-swappable. You can remove them from and inset them without having to power down the switch.

Use of non-3Com SFPs is not recommended. 3Com cannot guarantee operation of the switch if non-3Com SFPs are used.

8 Console Interface

Use the supplied DB-9 to RJ45 serial cable to connect to the switch’s command line interface. Default Settings are 38,400 baud, 8 data bits, no parity, no flow control.

9 10BASE-T/100BASE-TX/1000BASE-T Ports

Use suitable TP cable with RJ-45 connectors. You can connect your Switch to a work- station, or any other piece of equipment that has 10BASE-T/100BASE-TX/1000BASE-T connectivity. Each port is capable of autosensing for 10 Mbps, 100 Mbps or 1000 Mbps operation. All ports have an automatic MDI/MDIX feature, which means either straight-through or crossover cable can be used to connect to any port.
