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.
