Power Supply Connection
】
The top panel of this switch provides 4-pin DC power supply
input terminal blocks, and supports redundant power supply
input function. It provides two pairs of power supply input
terminals, PWR1 and PWR2, which
could be used individually or
connected to two independent DC
power supply systems. It uses two
pairs of terminal blocks to connect
to the device at the same time.
When any one of the power supply systems fails, the device
could operate normally without interruption, which has
improved the reliability of network operation. Voltage input is
48VDC (the definitions of terminal are V1-, V1+, V2-, and V2+).
The power supply supports anti-reverse connection.
【
Relay Connection
】
The access terminal of this relay is located
on the top panel of the device. Relay
terminal blocks are a pair of normally open
contacts in the alarm relay of the device.
They are open circuit in the status of normal
no alarm, and closed when any warning message occurs. The
product supports 1 relay warning message output, and
warning messages output of the DC power supply or network
abnormal alarm output. It can be connected to alarm indicator,
alarm buzzer, or other switching value collecting devices for
timely warning operating staffs when the warning message
occurs.
