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. Reset switch

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 switch is enabled by default. If the reset switch is disabled via the WEB UI, it will cease
functioning.

3. 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, the AUTO-MDIX function 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.

4. SFP ports

These are ports for attaching 1000BASE-LX and 1000BASE-SX modules. Optional modules (BS-SFP­GLR, 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.

5. USB port

This is a port for connecting USB devices. Only USB 1.1 and FAT32 are supported. The USB memory is
attached when the switch is shipped. (Formatted with the FAT32 le system)
Do not remove the USB memory during USB access or while the switch is starting.

Chapter 1 Product Overview

Cooling Fan

A fan for cooling the power supply is installed in the rear panel of the switch. If the fan stops, a
buzzer sounds and PoE functionality is disabled. Although switching still functions, turn o the unit
and disconnect power until the fan is xed. Prolonged usage in this state can result in a re due to
overheating.

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.

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.

Ignore :
No operation is performed for the port where a loop was detected.
However, the DIAG LED and LED for the port where the loop was
detected both blink, and the buzzer sounds for about 60 seconds. If
the loop is detected after 60 seconds, the 60-second buzzer sounds
again, and the operation is repeated.

Disable the port:
When a loop is detected in a port, the port is disabled only for
the number of seconds that was set in “Disable duration”. At the
same time, the DIAG LED and LED for the port where the loop was
detected both blink, and the buzzer sounds for the number of
seconds set in “Disable for:”.

Disable for: If “Disable the port “ was set for operation when a loop is detected,

this sets the time (seconds) that the port is disabled.
Range: 0 to 65535 seconds

MAC Thrashing This enables the MAC thrashing system of the loop detection

function.
A loop is recognized if the number of learned MAC addresses of this
switch exceeds the preset threshold value in 1 second.

LDF This enables the LDF system of the loop detection function.

This sends LDF packets at 1-second intervals. A loop is recognized if
the sent LDF packet is received.

Receive Rate This enables the reception rate system of the loop detection

function.
A loop is recognized if the preset reception rate is exceeded.

Received Data Threshold This sets the reception rate threshold value (1 to 1000 Mbps) for

recognizing a loop.

• If the time that was set in “Disable duration” has elapsed, the port is automatically enabled.

• The loop detection function temporarily disables a port when a loop is detected. It does not
prevent loops. The spanning tree function is used to block the port where the loop was detected; it
automatically switches the communication route to prevent a network failure. The Bualo switch
includes both functions. Use the function you need based on your environment.
