MCPS2000 System Operation 21
Spectrian Proprietary -- See notice on first page
3.2.2.2 Manual Alarm resets
When a major Alarm is detected the operator may choose from the following
options:
• Take no action and allow the MCPS2000 to operate in a degraded state until
service can be performed.
• Shed input channels to reduce the power to the MCPS2000.
• Disable the RF Module using the front panel switch, diagnostic port, or optional
base station alarm and control interface
• Enable the faulting RF using the front panel amplifier switch, diagnostic port, or
optional base station alarm and control interface, assuming that a false alarm has
occurred, and wait to see if the fault alarm returns.
☛ This action involves risk to the MCPS2000 and is not recommended by Spectrian.
Re-enabling an off-line MCPS2000 without determining the cause of the fault
could result in damage and void the product warranty.
