turned on.

dPort Status LEDs

The LEDs display status for each respective port.

LED State Indication

Steady A valid network connection established.

LNK stands for LINK.

LNK/ACT

Flashing Transmitting or receiving data.

ACT stands for ACTIVITY.

Steady

A valid 100Mbps network connection

established.

100 stands for 100Mbps.

100

Off

A valid 10Mbps network connection

established.

10 stands for 10Mbps.

Steady Connection in full duplex mode.

Physical Ports

This switch provides:

•Eight 10/100BaseTX ports

•Seven 10/100BaseTX ports + one 100BaseFX port

•Six 10/100BaseTX ports + two 100BaseFX ports

CONNECTIVITY

•RJ-45 connectors

•ST or SC connector on 100BaseFX fiber port.

MODE SELECTION

•10BaseT full-duplex mode

•10BaseT half-duplex mode

•100BaseTX full-duplex mode

•100BaseTX half-duplex mode

•100BaseFX full-duplex mode

•Auto-sensing mode (Copper Ports)

<Note>

i. Half-duplex mode uses back pressure flow control to prevent the receiving

buffer from being overrun by data from a source node.

ii. Full-duplex mode uses 802.3x flow control standard to prevent fast data

traffic from overrunning slow data traffic.

iii. Auto-sensing mode is in use after auto-negotiating with the other end of the

link.

Basic Functions

In general, the switch is responsible for switching both VLAN

tagged and untagged frames from a receiving port to one or

more transmitting ports. The switch performs multiple steps

during the switching process:

VLAN CLASSIFICATION

LEARNING

FILTERING

FORWARDING

AGING

Below is additional information about tasks that the switch

performs during unicast and multicast switching.
