Example Configuration with the PSAX 4500 Alarm Module The PSAX 4500 Alarm module is functionally identical to the Alarm module (model 20N79), but the module is designed to be mounted only in the rear panel (slot 14) of the PSAX 4500 chassis. This enables you to make maximum use of the front panel I/O slots. The module uses midplane bus traces that do not impact midplane bus utilization calculations. Like all of the other PSAX modules, the PSAX 4500 Alarm module is monitored and controlled through the console or EMS-PSAX. For a detailed description of the PSAX 4500 Alarm module, see the PacketStar PSAX 4500 Alarm Module User Guide. Alarm Outputs Alarm Severity Levels The PSAX 4500 Alarm module provides three severity levels of alarms Critical, Major, and Minor as reported by the following devices: LEDs on the module faceplate and chassis front panel Relay contact closures that activate external audible and visible alarms in the CO or NOC SNMP trap messages Visible alarms assist in identifying and locating the particular chassis that is in an alarm condition by activating the equipment bay alarm lights and chassis alarm indicators. Audible alarms also occur when an alarm condition exists in the CO or switch room. Alarms reported at each of the three severity levels Critical, Major, and Minor are interdependent. If a higher severity alarm condition occurs (such as Critical during the presence of a lower severity alarm (such as Minor), the Critical alarms (LEDs, visible, and audible) are activated and the Minor alarms are temporarily deactivated. Once the condition causing the higher severity alarm is cleared, the Critical alarms are deactivated, or cleared, and the Minor alarms are reactivated (if applicable).

9 Output Generation Criteria The generated alarms described in Table 5 occur under the following conditions: Table 5. Module Alarm Generation Criteria This Alarm occurs Under the following conditions CRITICAL MAJOR MINOR Loss of input power to the chassis all module LEDs do not illuminate but a Critical alarm is generated when the alarm relay becomes unpowered and causes the relay contacts to change position Failure of both CPUn modules Loss or Failure of both Stratum 3 4 modules Loss of both BITS clocks Loss of both Composite clocks Loss of both primary and secondary I/O timing references (if provisioned) Failure of one -48 V dc Power Supply module (including fan) Loss of one BITS or Composite clock timing reference source Failure of one Stratum 3 4 module in a redundant configuration Failure of one CPUn module in a redundant configuration Failure of one configured module Loss of signal or frame from a primary or secondary timing source when line timing is configured on the Stratum 3 4 module When more than one of the above conditions occurs in more than one category, the highest severity alarm determines which LED illuminates. Note: Output contact closures are not supported for a non-redundant Stratum 3 4 module configuration as this results in a permanent Minor alarm. Alarm Relay Operation The activation of the external alarms in the CO is controlled through six relays (three for visible alarms and three for audible alarms) with Form 1-C contacts (see Figure 7). The contacts normally open (NO), normally closed (NC), and common (COM) are accessible through the ALARM connector. PSAX 4500 Alarm Module Description and Specifications Page 9 of 18

ALARM Connector Configuration To allow flexibility in connecting the module to the external alarm panel: The Major and Minor alarm relays are energized only when an appropriate alarm condition occurs. The Critical alarm relays are normally energized when no alarms are reported. When a Critical alarm is reported or power fails, the relays are de-energized, causing contacts to change positions and in turn causing the CO alarms to be activated. Figure 8 illustrates how the PSAX 4500 Alarm module might be connected to a CO alarm panel. Diagram A shows an unalarmed condition. Diagram B shows an alarmed condition.

Generating Alarms Audible Alarm Cutoff (ACO) The alarm cutoff (ACO) function provides a method of silencing the audible alarms caused by an alarm condition being reported by the chassis; it has no effect on the visible alarms activated by the module. The alarm cutoff is controlled through the ACO switch on the module and from a remote ACO device (connected through the ALARM connector). A remote ACO device could be a switch, relay contacts, or software command. When an audible alarm occurs, pressing the module ACO switch or activating the remote ACO device once performs the following functions: Silences the audible alarms, but does not clear the alarm condition Illuminates the yellow ACO LED on the module Reports the change in state to the CPUn module Pressing the module ACO switch or deactivating the remote ACO device a second time performs the following functions: Reestablishes the audible alarm functionality Extinguishes the yellow ACO LED on the module Reports the change in state to the CPUn module PSAX 4500 Alarm Module Description and Specifications Page 11 of 18

12 The local and remote alarm cutoffs operate independently of each other. This change in state (on to off, off to on) is also shown in the Audible Alarm Status panel of the console Alarm Configuration window. Control Outputs The PSAX 4500 Alarm module can control up to four remotely controlled devices, such as air conditioning, heating, lighting, and so on, through four relays. The relays are controlled through the Control Outputs panel on the Alarm Module Configuration window. The Control Output relays have Form 1-C contacts (normally open (NO), normally closed (NC), and common (COM)) that are accessible through the STA- TUS/CONTROL connector (see Figure 9). The contact configuration allows flexibility in connecting the module to remotely controlled devices. Control Output relays 1, 2, and 3 are normally in an off state (COM and NC contacts closed) when no command is sent. They are energized (changed from a normal off state to an on state) only when a control command is sent. Control Output relay 4 is normally energized (COM and NO contacts closed) when no command is sent. When a control command is sent, the relay is not energized causing the COM and NC contacts to close and in turn causing the external device to be activated or deactivated.

13 Figure 10 shows how the module activates a Control Output relay to activate the supplemental air conditioning. The command maintains the contact closure for 30 seconds, which means the remote device must have the capability of sustaining itself until the situation resolves itself, such as when the air temperature returns to normal.

Activating Supplemental Air Conditioning Remote Status Inputs Fifteen remote status inputs are provided through the STATUS/CONTROL connector to enable remote sensors to be monitored and reported to the NOC. Opto-isolators are used to monitor the opening and closing of dry contact relays in devices that can report their own operational status. An input and common connection is provided for each opto-isolator. An example of a remote sensor would be a door sensor that indicates whether the door is open or closed as shown in Figure 11.
