1.Indicators
Indicators are located on the front panel of the product. The functions of
each indicator are shown below.
LOOP (Red)
Blinking : Loop detected (blinks at 1 second intervals)
O : Nomal
POWER (Green)
On : Power on
O : Power o
PoE (Green or Orange)
On (Green) : PoE power is available
On (Orange) : Overcurrent or excessive power draw
O : PoE power is disabled
1000M (Green)
On (Green) : 1000M Link
O : 100M or 10M Link, No Link
LINK/ACT (Green)
On : Link established
Blinking : Data transfer
O : Link not established
2. Loop detection switch
This switches loop detection on and off. After flipping the switch,
disconnect and reconnect the power cable.
3. PoE ports
These ports support PoE. Connect devices that need Ethernet power
to these ports. Each port can supply up to 15.4 Watts with a maximum
total of 40 Watts for all 4 ports.
All ports support autonegotiation. The optimal duplex mode (full
duplex or half duplex) and transfer speed (1000, 100, or 10 Mbps) are
selected automatically.
4. Uplink port
Connect other hubs or switches to this port. This port doesn't support
PoE.
5.Power connector
Connect the included power cable to this connector.

Installation
Precautions for Installation
• Do not install the device in an unstable location such as on an unsteady
table or an inclined surface.
• Do not place another hub or object that generates heat on this unit.
• Please route LAN cables properly to prevent people from tripping over
them.
• Ensure the air vents on the product are not blocked by other equipment
or walls.
• Only use the power cable included with the product. Using other power
cables may result in damage or re.
Floor or Shelf Mounting
Attach the supplied rubber feet to the bottom corners of the unit before
use.
Mounting to a Metal Surface
To mount to a metal surface, such as the side of a steel desk, use the
"BS-MGK-A Magnet Kit" (sold separately).
Caution: Do not put floppy discs, magnetic cards, or other magnetic storage
media near magnets. Doing so may delete or corrupt data.
Wall Mounting
To mount the unit to a wall, use 2 screws (not included) with the dimensions
shown below. Install the screws 113 mm apart and slide the mounting holes
in the base of the BSL-POE-G2105U over them.
Mounting
holes
Use screws where this section
is 2 mm or less.
Loop Detection
This unit can detect network loops that can cause interference in the
network.
What is a Loop?
If both ends of an Ethernet LAN cable are connected to the same hub, or
when multiple connections exist between two hubs, data may be sent in a
loop around the network, wasting network capacity and never getting to its
destination. This continuously circulating data may interfere with other
network communication.
Loop Detection
･Off: Loops are not detected.
･On: If a network loop is detected, the loop LED on the front of the
BSL-POE-G2105U will flash red once per second.
Turning Loop Detection On and Off
1. Use the switch on the front of the BSL-POE-G2105U to turn loop detection
on or o .
2.After changing the switch position, disconnect and reconnect the power
cable. The change will take e ect when the BSL-POE-G2105U has rebooted.
Notes:
・ While loop detection is enabled, the BSL-POE-G2105U will send a loop
detection packet through the network every two seconds. If these
packets disrupt your network in any way, disable loop detection.
・ Loop detection cannot detect all types of loops.
When a Loop is Detected
Reconnect the wiring, making sure that no wires are connected in a
loop.
