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 fixed.
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-SFP-
GLR, BS-SFP-GSR) (sold separately) are required to use these ports. These support autonegotiation and flow 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 file 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 off the unit and disconnect power until the fan is fixed. Prolonged usage in this state can result in a fire 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 differs 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.

When the settings are changed while a USB device is inserted in the device, ”default.cfg” is created on the USB device, and synchronized with the settings on the product. The latest settings file is always saved to ”default.cfg” on the USB device.
”default.cfg” under the root directory of the USB device is loaded upon booting.
A backup of the configuration file is automatically saved to the USB device when the configuration is changed.
If enabled, the settings file is automatically saved to “default.cfg” and “yyyymmdd.cfg” on the USB device whenever configuration changes are made.
The latest version is always saved to “default.cfg”, and the version before the latest settings file is saved to “yyyymmdd.cfg”.
default.cfg:
The latest settings file is synchronized with the product.
yyyymmdd.cfg:
This indicates the date set on the switch. The settings file from before the change in settings is saved as a backup.
Example:
If the settings are changed on October 1, 2012 while Auto-save is enabled, the settings file for after the change in settings is saved to the USB device as “default.cfg“ and the settings file from before the change in settings is saved as “20121001.cfg“ as a backup.
If several changes are made to the settings file on the same day,
“yyyymmdd.cfg“ is overwritten.
