DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 LED Indicators Page 7-3 Circuit Pack LEDs 7 Circuit Pack LEDs Each circuit pack typically has three LEDs on the front panel visible at the front of the carrier, there are some exceptions to this (for example DS1CONV circuit pack) that are covered later in this section. On most circuit packs, the LEDs indicate the following when lit. Exceptions to these indications are explained in subsequent sections. LED Alarms without Alarm Log Entry or with Error Type 1 Whenever the system or a part of the system is reset, all affected circuit packs will briefly light their red and green LEDs as they are initialized. Upon power-up of a newly installed system, several alarm indicators may remain lit until the circuit packs are administered. These alarms should be ignored until administration is completed. During routine or demand testing of Mass Storage System components, the red, green and yellow LEDs on the MSSNET, TAPE, and DISK circuit packs all light temporarily. This is normal and does not indicate a problem. After a circuit pack has been initialized, a lit red LED should be accompanied by an alarm in the Alarm Log. A single fault can sometimes light alarm LEDs on several circuit packs, as in the following examples. nA TDM bus problem may cause several port circuit packs to display red LEDS. nAn EPN Maintenance circuit pack can prevent an Expansion Interface circuit pack from initializing. nExtensive interactions in the Center Stage Switch can cause multiple alarms from single faults in DS1C, SNI and SNC circuit packs and fiber links. nTone/clock problems may cause other circuit packs to report alarms. Red Alarm The system has detected a fault in this circuit pack. The Alarm Log should contain an on-board alarm for this circuit pack or one of the maintenance objects associated with it. The red LED is also lit briefly when a circuit pack is inserted or reset. If the circuit pack passes its initialization tests, the LED is extinguished. If a fault is detected, it remains lit. Green Testing The system is currently running tests on this circuit pack as part of background maintenance or demand testing. This LED is also lit briefly during initialization tests when a circuit pack is inserted or reset. Yellow Busy The circuit pack is currently in use by the system.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 LED Indicators Page 7-4 Expansion Interface Circuit Pack LEDs 7 nMisconnected optical fiber cables may cause several circuit packs to alarm. nPacket bus faults can cause several port circuit packs to display red LEDs. If a circuit pack has had at least five minutes to be initialized, and the red LED is lit without an associated alarm in the Alarm Log, the circuit pack may not be in communication with the system. This may also be the case when a circuit pack is properly administered and present in its slot, but there is an error type 1 logged against it. To determine if this is so, proceed as follows: nIssue the list configuration board UUCSS command. If the system does not detect the circuit pack, this command will return identifier not assigned or no board. If the documentation for the associated maintenance object gives no special instructions for this situation, go to the next step. nCheck the Hardware Error Log for TONE-BD or TDM-BUS errors. Use the test tdm and test tone-clock commands and use the appropriate maintenance procedures to resolve any identified faults. If this does not resolve the problem, go to the next step nReseat the suspect circuit pack. !CAUTION: This procedure can cause a partial or total service outage. Consult thoroughly the documentation for the associated maintenance object before proceeding. Observe the precautions and procedures described above. nInspect the backplane connectors for bent pins. nIf the system seems to be functioning correctly, but the circuit pack in question will not communicate with the system, replace the circuit pack. Expansion Interface Circuit Pack LEDs The Expansion Interface (EI) TN570 circuit pack has the standard red, green and yellow LEDs. The red and green LEDs have the traditional meaning, where red indicates an alarm condition, and green indicates testing in progress.
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 LED Indicators Page 7-5 Maintenance Circuit Pack LEDs 7 The yellow LED displays various flashing patterns to provide status information useful in isolating faults in the fiber link and other components connected to the fiber link. Table 7-1 illustrates the EI yellow LED states. Maintenance Circuit Pack LEDs TN1648 System Access-Maintenance (SYSAM) and TN775 EPN Maintenance circuit packs have seven LEDs on their front panels. The top three LEDs are the standard group of red, green and yellow, and indicate the status of the circuit pack. The green LED on TN775s blinks faintly once per second, indicating continual self-testing. The second group of three LEDs, labeled “ALARMS”, reflect maintenance conditions throughout the system, and indicate alarms reported against other components, as described below. On systems with duplicated SPEs, disregard the Major, Minor, and Warning alarm LEDs on the standby SYSAM circuit pack. Table 7-1. Expansion Interface Yellow Led Flashing Codes LED on LED off Condition 0.1 sec 0.1 sec Fiber Out-of-Frame. This state indicates a failure of test #989. This may be caused by absence of the opposite end EI or Switch Node Interface, a broken or missing fiber, or a missing lightwave transceiver on either endpoint. 0.5 sec 0.5 sec In Frame — No Neighbor. This state corresponds to a failure of test # 237, usually due to a failure of this EI or of the EI or SNI at the other end of the fiber. 2 sec 0.2 sec Expansion Interface Active. This is the normal state of an active EI that is an archangel of an Expansion Port Network. solid on Expansion Interface Active. This is the normal state for an active EI that is not an EPN archangel. These include EPN EIs connected to other EPN EIs in Direct Connect Configurations, and EIs located in the Processor Port Network. solid off Expansion Interface Standby. This is the normal state for a standby EI in systems with a duplication option.

The yellow LED that is third from the top indicates which SYSAM is active. These LEDS are illustrated on the following page.MAJOR (red) flashing Major Alarm against a component in the same cabinet, (PPN for SYSAM, and EPN for MAINT). MAJOR (red) solid Major Alarm against a component in another cabinet in the system. MINOR (red) flashing Minor Alarm against a component in the same cabinet.

SYSAM and EPN Maintenance Circuit Pack LEDs Duplication Interface Circuit Pack LEDs In systems with duplicated SPEs, (High Reliability and Critical Reliability), there are two Duplication Interface UN330B circuit packs. One is located in carrier A and one in carrier B of the PPN. Each circuit pack has four LEDs. The top three have the traditional function of indicating the status of the pack. The LED located at the bottom of the faceplate directly beneath the SPE Select switch is labeled OVERRIDE. Under normal operating conditions, the SPE Select switch is in the AUTO (center) position, and the OVERRIDE LED remains unlit. This means that the system controls which SPE is active. System selection of the active SPE can be manually overridden by moving the SPE Select switches from the AUTO position to either the “A” position or the “B” position on both Duplication Interface circuit packs. At this time, the red OVERRIDE LEDs on both Duplication Interface circuit packs will light steadily to indicate that one SPE is locked Active and the system is not duplicated. If both SPE Select switches are not in the same position, the system software retains control of Active SPE selection, and the OVERRIDE LED remains unlit. When control of the SPE selection is returned to the system by returning the SPE Select switches on both Duplication Interface circuit packs to the AUTO position, the OVERRIDE LED will go dark. Forced SPE selection should be undertaken only after consulting the appropriate sections in Chapter 9, ‘‘ Maintenance Object Repair Procedures’’.

TN574 Circuit Pack LEDs Seven LEDs provide an indication of the state of the DS1 Converter (DS1 CONV) TN574 circuit pack and the DS1 facilities. The top group has the standard red, green and yellow LEDs. The red and green LEDs have the traditional meaning, where red indicates an alarm condition, and green indicates testing in progress. The four green LEDs on the bottom indicate the status of the DS1 facilities (see following section). Table 7-2. Switch Node Interface Yellow Led Flashing States LED on LED off Condition 0.1 sec 0.1 sec Fiber Out-of-Frame. This state indicates a failure of test #238, which may be caused by absence of the opposite end EI or Switch Node Interface, a broken or missing fiber, or a missing lightwave transceiver on either endpoint. 0.5 sec 0.5 sec In Frame — No Neighbor. This state corresponds to a failure of test # 237, usually due to a failure of this SNI, or the EI or SNI at the opposite of the fiber. This condition may also be due to a faulty Switch Node Clock. solid on SNI Active. This is the normal state for an active SNI. solid off SNI Standby. This is the normal state for a standby SNI in systems with a duplication option.

DS1 Facility LEDs Below the three standard LEDs on the DS1C circuit pack are four green LEDs used to indicate whether a receive signal is present for each of the four DS1 facilities. Figure 7-3 shows which facility (A, B, C, or D) corresponds to each LED. If a green LED is off, there is a Loss of Signal condition on the DS1 facility associated with that LED. The presence of a signal does not guarantee that the signal is using the correct framing format or line coding; an Alarm Indication Signal indicating that the opposite end of the DS1C complex is out of service may be present. Table 7-3. DS1C Yellow Led Flashing States LED on LED off Condition 0.1 sec 0.1 sec Fiber Out-of-Frame or Fiber Loss of Signal 0.5 sec 0.5 sec In Frame, fiber channel down. The fiber channel communicating between the DS1C and the other fiber endpoint (EI or SNI) is down. 1 sec 1 sec In Frame, DS1 channel down. The channel between the two DS1Cs in the DS1C complex is down. 2 sec 0.2 sec No response from SPE. The SPE is not acknowledging messages from the DS1C or the communications link to the SPR is down. solid on DS1C active. This is the normal state for an active DS1C. solid off DS1C standby. This is the normal state for a standby DS1C in Critical Reliability Systems (duplicated PNC).
DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 LED Indicators Page 7-11 DS1 CONV (TN574/TN1654) Circuit Pack LEDs 7 Figure 7-3. TN574 DS1C Circuit Pack LEDs TN1654 Circuit Pack LEDs The TN1654 DS1CONV board has 11 LEDs on its faceplate. The top 3 system standard LEDs indicate the state of the DS1CONV board. These LEDs are under firmware control until the board has established a link to the SPE via the EI or SNI. Once the link is established, software controls the 3 LEDs. If the link breaks, the LEDs are again under firmware control. The red and green LEDs have the traditional use: red means an alarm condition, and green indicates that maintenance testing is in progress. The red and green LEDs are also turned on during circuit pack initialization by firmware. When the control link to the circuit pack is lost, firmware controls the red LED to indicate an alarm condition. The yellow LED under firmware control is used to indicate the state of the physical Fiber Interface, the Fiber Channel (link to EI or SNI), the DS1 Control Channel (link to opposite DS1CONV board), and the SPE communications link in the following manner and order of priority. (The yellow LED remains on for longer periods of time as the DS1CONV Complex becomes closer to being fully operational.) 1. If the Fiber is Out of Frame or if a Fiber Loss of Signal condition exists, the yellow LED will flicker at a 5 Hz rate (on for 100 mS, off for 100 mS).

If the Fiber Channel is down (DS1 Converter circuit pack/fiber endpoint communications), the yellow LED will flash at a 1 Hz rate (on for 500 ms, off for 500 ms). 3. If the DS1 Control Channel is down between the two DS1CONVs in the DS1CONV Complex, the yellow LED will pulse at a 0.5 Hz rate (on for 1 second, off for 1 second). 4. If the SPE communications link is down, the yellow LED will wink off every 2 seconds for 200 ms (2 seconds on, 200 ms off). 5. If all is well with the Fiber Interface and all communications channels, the yellow LED will remain on continuously in a Standard Reliability and High Reliability System configuration. In Critical Reliability systems (duplicated PNC), an active DS1CONV circuit pack will have its yellow LED on continuously, and a standby DS1CONV circuit pack will have its yellow LED off. The LED will then be under software control. The bottom four green LEDs on the TN574 DS1CONV board are under hardware control. The four green LEDs indicate, for each DS1CONV facility, whether a receive signal is present for the DS1 facility The next four LEDs on the TN1654 DS1CONV board are labeled STATUS LEDs and are for future use. These LEDs will not be lit. The bottom four LEDs on the TN1654 board are labeled SPAN LEDs. These LEDs are under firmware control. If the facility is not administered, then the LED is not lit. The LED is lit amber if the facility is running alarm free. If the facility is detecting either a red alarm (loss-of-signal or loss-of-frame), a yellow alarm (remote frame alarm) or a blue alarm (AIS signal) then the LED is lit red. The SPAN SELECT Switch on the TN1654 faceplate is for future use. Pushing the switch will have no effect on the board. See Figure 7-4 for a view of the face plate on the TN1654 DS1CONV circuit pack
