Installation
Installation Notes
• Do not install on an unstable location such as a wobbly stand or slanted surface.
• Do not place other devices or objects that generate heat on top of this product.
• Arrange the cables neatly to avoid entangling your feet or objects in them.
• Do not block the ventilation holes of the PSA-2400U with another device, walls,
or other objects.
• Be sure to always use the power cord supplied with the PSA-2400U. Cords for
other products will have different specifications, and their use could cause a
breakdown of the PSA-2400U or a fire.
Mounting to a Wall
The PSA-2400U is mounted to a wall using the supplied mounting brackets or the
mounting holes on the bottom. When using the mounting brackets, use the
mounting screws as shown in the figure below, and secure the mounting fixture
and the PSA-2400U.
To mount the unit directly to the wall, attach the screws to the wall first and then
slide the holes on the bottom of the PSA-2400U over the screws.
Before mounting to a wall, check that the wall surface has sufficient strength, and
secure firmly so that the main unit, power cord, and LAN cables do not fall due to
their weight.
Installing on 19-inch Rack
Install as shown in the figure below by using the supplied mounting brackets.

100BASE-T/100BASE-TX/10BASE-T ports
These are ports for connecting 100BASE-T/100BASE-TX/10BASE-T devices.
These ports are also used when two hubs are connected in a cascade
configuration. The transmission speed is recognized automatically.

The PSA-2400U includes a function for blocking a network loop which can
cause interference in the network.
What is a loop?
A loop is a configuration where the data continues to cycle around the
network, such as when both ends of a LAN cable are connected to the
same hub, or hubs are connected in a looped (circular) configuration. If the
data continues to cycle around, network communication can be impaired
and may eventually fail.
Loop blocking operation
OFF : Loops are not blocked.
ON : If a loop is detected, the port is blocked until the loop is broken. Also, the Loop
Block LED and the LED for the blocked port on the front of the PSA-2400U flash,
and a buzzer sounds.
To stop the buzzer, set the loop blocking switch to OFF.
Switching the loop blocking function ON/OFF
1. The loop blocking switch on the front of the PSA-2400U can be switched ON or OFF.
2. Unplug the power cord from the outlet and then plug it in again.
The setting of the switch doesn't take effect until power is disconnected and
reconnected.
When a loop is detected
Reconnect so that the cables are not connected in a loop.
The loop blocking LED will continue to flash until the loop is broken and
the power is turned OFF and then ON again.
CAUTION
OFF ON OFF ON
Loop Detection
• When the loop blocking function is set to ON, loop detection packets are sent
regularly (approx. 2-second intervals) from the PSA-2400U. If you do not want loop
detection packets to be sent, use with the loop blocking function set to OFF.
• The loop blocking function does not prevent interference from every possible type of
loop.

Basic Specifications
For the latest product information and compatible models, refer to our
product catalog or website (www.eneo-security.com).
*1 Because the PSA-2400U automatically recognizes the cable type (straight or
cross cable), either cable can be used without any problems.
*2 The use of self-manufactured cables can cause the network to fail to operate
properly. Please use cables that are available commercially.
If you are unable to connect to a network
Check the following points.
• Is the power cord connected to this product? Also, is the power cord
plugged into the outlet?
• Are the UTP cables connected correctly? Are any cables disconnected
or broken?
• Are any Link/Active LEDs lit?
*3 See “Loop Detection”on this sheet.
*4 The power save function automatically recognizes the port link status and LAN
cable length and adjusts the operating power accordingly.
