Chapter 3 Maintenance 96-30052-001 Rev.
Monitoring the SS8460 3.1 Monitoring the SS8460 The SS8460 provides visual indications (LCD and LEDs) for operational status. An audible alarm (piezoelectric buzzer) indicates a faulty condition such as the top cover is open or a PCM has been removed. 3.1.1 LCD Module The LCD module provides system status information (Figure 38). The display cycles through the identification and status pages (Figure 39).
Monitoring the SS8460 3.1.2 Enclosure Status LEDs There are seven LEDs, five on the front panel (Figure 40) and two on the back (Figure 41) of the enclosure, that show the aggregated status of all the modules. Table 1 provides a description of the color and status of the LEDs. Figure 40. Enclosure Status LEDs at the Front Figure 41. Enclosure Status LEDs at the Back Locate Beacon System Fault Table 1.
Monitoring the SS8460 3.1.3 Disk Locate and Status LEDs There are two status LEDs for each disk module (Figure 42). Table 2 provides a description of the color and status of the two LEDs. Figure 42. Status LEDs on Disk Module Table 2. HHD LED Indicators Color Blue Amber Status ON (flashing) - receiving Locate command OFF - NOT receiving Locate command ON - a disk/bay fault has been detected OFF - no detectable fault is present Flashes - a disk/bay fault is predicted 1 1.
Monitoring the SS8460 3.1.4 I/O Module LEDs There are LEDs mounted on the I/O module to indicate the status of the module. Figure 44 shows the location of the LEDs on the module. Table 3 provides a description of the color and status of the LEDs. Figure 44. LEDs on I/O Module Fault LED Link Established LED Power LED Link Fault LED Module OK LED Locate Beacon Table 3.
Monitoring the SS8460 3.1.5 Power and Cooling Module LEDs There are four LEDs mounted on the PCM to indicate the status of the module and the fans. Figure 45 shows the location of the LEDs on the module. Table 4 provides a description of the color and status of the LEDs. Figure 45. Power and Cooling Module LEDs Table 4. PCM LED Description LED 96-30052-001 Rev.

Table 5 provides a description of the color and status of the LEDs. Figure 46. 5V Regulator LEDs Table 5. 5V Regulator LED Description LED 3.1.
Monitoring the SS8460 3.1.8 Temperature Sensor Locations The SS8460 enclosure contains 9 temperature sensors located throughout the enclosure: • Two sensors distributed on the baseboard measuring true ambient inlet air temperature to the enclosure. Each ambient temperature sensor is connected to an independent I2C bus for redundancy. • One sensor is located at the inlet to each PCM. • One sensor on each I/O module measuring the air temperature behind the expanders within each I/O module.
Component Failure Recovery 3.2 Component Failure Recovery The SS8460 contains redundant and hot-swappable components: • Power and cooling module • Disk module • I/O module • 5V regulator • LCD module (hot-swappable only) A single component failure, therefore, will not shut down the system. However, in the unlikely event of component failure, you can replace the failed component while the system is running.
Component Failure Recovery 3.2.1 Replacing a Power and Cooling Module If a power supply or fan fails, the Fault LED on the PCM will turn amber. If a power supply unit or its fan is faulty, you must replace the whole PCM. You must not take any longer than 5 minutes to replace this module to prevent the enclosure from over-heating. NOTE : If replacement of a PCM is required, the fans in the other PCM will increase to maximum speed when the failed module is removed. This is to maintain proper cooling.
Component Failure Recovery 3.2.2 Replacing an I/O Module NOTE : When an I/O module is removed, the fans (in the PCMs) will increase to maximum speed. This is to maintain proper cooling inside the enclosure. Fans will return to normal operation when the replacement I/O module is inserted and powers up. To replace an I/O module: 1. Identify the failed I/O module with an amber Fault LED. 2. Label the cables as they will need to be connected to the same ports on the replacement module.
Component Failure Recovery 3.2.3 Replacing a Disk Module When a disk is failed by the SS8460, replace it promptly so that the operation and performance of the system are not affected. CAUTION : Disk spin down--Damage can occur to a disk if it is removed while still spinning. DDN recommends that you perform ALL steps of the following procedure to ensure that the disk has stopped prior to removal. NOTE : Opening the cover affects the system cooling. Limit service time to 5 minutes.
Component Failure Recovery To insert a module: 1. On the replacement module, press the release latch to release the handle. 2. Insert the module into disk bay. Note the orientation of module. 3. Continue to slide the module down until it contacts the baseboard and begins to engage the handle. Carefully press down on the handle until it latches which will cam the disk module into place. 4. Close the enclosure cover. 5. Swing down both handles completely to engage the locks.
Component Failure Recovery 3.2.5 Replacing a LCD Module NOTE : The LCD module is not a redundant component, but the enclosure will remain operational if the LCD module is broken or if it is removed. The LCD FRU kit includes the LCD PCBA and the cable (Figure 52). Figure 52. LCD FRU Kit To replace the LCD module: 1. Detach the bezel from the enclosure by removing the four screws from behind. 2. Detach the LCD PCBA and cover from the front panel by removing the four screws as shown in Figure 53.
