1. Indicators
Indicators are located on the front panel of the switch. The functions of each indicator are are shown
below.
LED Status
Power (green) On: Power is on.
O: Power is o.
USB (green) On: USB device inserted
Blinking: Accessing the USB memory device
O: USB device removed
Diag (green or red) On (green): Normal
On (red): Hardware reset button was activated during startup or
during self-diagnosis
Blinking (red): Loop was detected by loop detection function
1000/100/10M (green or orange) On (green): 1000M link established
On (orange): 100M link established
O: 10M link established or no link established
LINK/ACT (green) On: Link established
Blinking: Data transmission is in progress
O: No link established
2. 1000BASE-T/100BASE-TX/10BASE-T ports
Each port supports autonegotiation. The optimal duplex mode (full-duplex/ half-duplex) and
transfer speed (1000 / 100 / 10 Mbps) are selected automatically.
Each port also supports auto-MDIX. As the port type at the other end is determined automatically,
there is no need to make a selection of either a straight cable or a crossover cable.
However, auto-MDIX is disabled if the transfer speed and duplex mode are xed.
The shared ports and SFP ports only support auto negotiation.
Note: When using 1000BASE-T, use a IEEE802.3ab compliant cable that supports Category 5e or higher as the
connection cable.
3. SFP ports
These are ports for attaching 1000BASE-LX and 1000BASE-SX modules. Optional modules (BS-SFP-
GLR, BS-SFP-GSR) (sold separately) are required to use these ports. These support autonegotiation
and ow control and operate in full-duplex mode with a transfer speed of 1 Gbps.
The shared ports cannot be used at the same time as SFP ports. When cables are connected to SFP
ports, shared ports are disabled.

4. Reset button
If this switch is held until the diag indicator is lit (approx. 3 seconds), the switch settings can be
restored to their factory defaults.
The reset button is enabled by default. If the reset button is disabled via the web UI or the command
line, it will cease functioning.
5. USB port
This is a port for connecting USB devices. Only USB 1.1 and FAT32 are supported. A FAT32-formatted
USB memory device is attached when the switch is shipped.
Do not remove the USB memory while it is being accessed or while the switch is booting.

MAC Address Learning
The switch uses IVL to learn MAC addresses.
IVL is a method that retains a MAC address table for each VLAN. It diers from SVL, which retains a
shared MAC address table for the entire device.
Be sure you understand how IVL works before you create a VLAN with the switch.
Dierences between Operation of IVL and SVL
VLAN 1,3 VLAN 2,3 VLAN 1,2,3 VLAN 3
VLAN 1 VLAN 2 VLAN 1 VLAN 2
PC 1 PC 2
PC3
Switch 1
Switch 2
SVL
When PC 1 and PC 3 communicate,
PC 3 is learned by Port 1 on Switch
2 so PC 2 and PC 3 cannot
communicate.
IVL
When PC 1 and PC 3 communicate,
PC 3 is learned by both VLAN 1 and
VLAN 2 so PC 2 and PC 3 can
communicate. However, frames
sent from PC 3 to PC 1 are also
delivered to PC 2.
