Installation and Operation
1SFP Ports
Two high speed SPF ports are available, typically used for a
fiber connection.
2Ethernet Connections / PoE Outputs (1 - 8)
These ports provide the connections between the LAN and
the connected network devices while also supplying PoE
power. These ports accept standard RJ45 cables.
3Reset Button (Reset)
Pressing the recessed reset button with a pin for a length of
time will reset the BTS500 as follows:
10 Seconds User Name & Password Only
20 Seconds User Name, Password, and IP Settings
NOTE - The user name and password will both reset to "ad-
min". If pressed for 20 seconds, the IP address will reset to
192.168.1.9 and the other IP settings will return to default.
4Power Meters (Power 1-4 & Power 5-9)
These meters display voltage and current for the labaled
groups of ports. The left side meter provides power informa-
tion for ports 1-4, while the center meter provides informa-
tion for ports 5-9.
5Power Meters (Battery)
This meter displays voltage and current for the connected
battery set. If no battery set is connected, this meter will
show no values.
6AC Line Input (AC Power)
This is the connector for the AC line cord. Plug the included
computer-style line cord into this connector. Connect the
other end of the cord to the power strip inside the rack or an-
other suitable AC power receptacle. The BTS500 series has a
universal input and accepts 90-265VAC input.
7Main AC Power Switch / Circuit Breaker (On/Off)
This is the main AC power switch for the BTS500. This switch
lights when power is on and also has a built-in circuit breaker
rated at 15A. If the circuit breaker trips, reset it by cycling the
switch to off then back to on.
8External DC Voltage Input (External DC +/-)
This input may be used to either power the BTS500 via an
external 50VDC supply or to provide battery backup to the
BTS500. The “External DC” input is reverse polarity protected.
See below for details:
To Use Battery Backup
Connect AC power to the BTS500 unit as normal. In addition,
connect a 48V nominal battery set to the “External DC” con-
nector, using the battery cable supplied.
To Use an External 50Vdc Supply
Connect a 50V power supply to the “External DC” connector
at the rear. The ratings requirements for the DC power supply
are given below:
Input voltage range 44 –57 VDC
Max input current (500W model) 14.0 A
Max input current (250W model) 7.0 A
Note that if both AC and DC power sources are connected to
the unit at the same time, the AC source will supply the power
to the output ports. The external DC source will not supply the
outputs unless the AC source is missing or the power switch is
turned off.
9Fire Alarm Input (For BX50 SFI Mode)
This input accepts an input from a Fire Alarm Control Panel
(FACP) to activate SFI mode when used with BX50 PoE split-
ters. See section 1.3 for more information on the Fire Alarm
Input and SFI mode.
bk RS485 Connection (B, A, GND)
This connector provides an RS485 connection between the
BTS500 and any connected LSP accessory boards with an
RS485 connection, such as a Generation 2 M8 or M8P.
The following are basic descriptions. Refer to the appropriate section for more detailed information. Note that the front
panel may appear different based on the configuration of your system.
