Description
Indicates whether the current
configuration has been saved. The value
can be true or false. If false, the
configuration is not saved.
Read-only
Can be disregarded when operating
amplifier in Constant Gain Temperature
Compensated mode (manufacturer
default) and Constant Pump Current
mode. Setpoint object is only valid when
amplifier is used in Constant Output
Power and Idle modes.
Read-write Can be disregarded when operating
amplifier in manufacturer default
Constant Gain Temperature
Compensated mode. Deviation object is
only valid when amplifier is used in
Constant Output Power and Idle modes.
Read-write Can be disregarded when operating
amplifier in manufacturer default
Constant Gain Temperature
Compensated mode. Hysteresis object is
only valid when amplifier is used in
Constant Output Power and Idle modes.
Read-write Alarm notifies operations personnel if
the optical input signal of the
ONS 15216 EDFA2 drops below a level
that impacts proper operation of optical
network. Set this attribute at a value that
is appropriate for the intended
application so that the alarm condition is
meaningful. Consult with the Cisco TAC
to determine the threshold value for your
application. As a guideline, Cisco
recommends setting the threshold value
at 3 dBm below the current input power
level of the amplifier. Valid entries are
between –3100 and –1500 in dBm times
100. For example, if the total input power
of the amplifier is –24 dBm and the loss
of input power threshold required is –27
dBm, the loss of input power alarm
threshold is –2700.
