3 Getting Started Introduction In this chapter, you are shown how to install your SR1202 enclosure into an industry standard 19 inch rack cabinet. ! CAUTION When connecting up the SR1202 enclosure, use only the power cords supplied or cords which match the specification quoted in section “Power Cords” on page 24. Planning Your Installation Before you begin installation you should become familiar with the configuration requirements of your SR1202 enclosure, detailed in Table 5.
Enclosure Drive Bay Numbering Convention The enclosure drive bay numbering convention is shown in Figure 23. A drive bay is defined as the space required to house a single 1.0“ high 3.5 inch disk drive in its carrier module. ! IMPORTANT Drive carrier module must always be fitted in drive locations 1 and 12. This is the minimum configuration required for the system to operate and provide SES Management Services.
Rack Mounting Rail Kit A set of mounting rails is available for use in 19 inch rack cabinets (Figure 24). These rails have been designed and tested to handle the maximum enclosure weight and to ensure that multiple SR1202 enclosures may be installed without loss of space within the rack. Use of other mounting hardware may cause some loss of rack space. The rack mounting rail kit also incorporates a rear hold down mechanism to ensure shock and vibration immunity.
Module Installation The SR1202 enclosure is supplied fully populated with all plug-in modules installed. For information on removal/replacement of plug-in modules, please refer to Chapter 5, ”Troubleshooting and Problem Solving”, on page 39. Management Interfaces The following management interfaces are provided and used to configure, manage and monitor the SR1202 RAID Controller Module Storage Solution.
Enclosure Configuration SR1202 enclosures are configured with one internal domain of 12 drives per SR1202 RAID Controller Module. Fibre Channel Interface The SR1202 RAID Controller Module provides two Fibre Channel SFP interface connections. The SR1202 RAID Controller Module provides bi-directional connection between the Fibre Channel host side interface and the drives. The drives will not be presented to the Host until they are configured and mapped by the controller.

Enclosures Expansion Additional JBOD or EBOD enclosures, e.g. SJ1202, can be connected to a SR1202 RAID enclosure. Multiple enclosures are connected together using SAS patch cables, up to a maximum of 6 enclosures, a typical configuration is shown in Figure 30. SR1202 Enclosure SJ1202 Expansion Enclosure 1 SJ1202 Expansion Enclosure 2 SJ1202 Expansion Enclosure N Figure 30.
Activating the Locks 1. Carefully insert the lock key provided into the cutout in the handle. 2. Locate the key into its socket. 3. Rotate the key in a clockwise direction until the indicator is visible in the aperture beside the key. Figure 31. Activating the Anti-tamper Lock 4. Remove the key. De-activation is the reverse of this procedure, that is: • Rotate the key in an anti-clockwise direction until the indicator is no longer visible in the aperture beside the key.
Grounding Checks Perform these checks to ensure that a safe grounding system is provided. • If a rack distribution system is being used: – Ensure power is removed from the rack. – Connect the SR1202 power cord to the rack distribution and the enclosure. • If a direct connection is made with the SR1202 power cord, ensure that it is connected to the enclosure. ! WARNING Some electrical circuits could be damaged if external signal cables or power control cables are present during the grounding checks.
4 Operation Before You Begin Before powering up the SR1202 enclosure please ensure that all the modules are firmly seated in their correct bays. Power On ! CAUTION Do not operate this equipment until the ambient temperature is within the specified operating range. If the drives have been recently installed ensure they have had time to acclimatize before operating them. NOTE Please refer to section “Ops Panel LEDs” on page 40 for details of the Ops Panel LEDs and related fault conditions.
Power Down The enclosure can be powered down at any time and if cached contents are present (refer to the Cache Active LED on the RAID controller module), they will be preserved by the internal battery. It is therefore recommended that, especially if the unit is to be powered down for extended periods, the controller is shut down prior to powering off the enclosure. 1. Shut down is requested at the GUI interface, please refer to MAXDATA SR1202 M1 – StorView® RAID User Guide. 2.
5 Troubleshooting and Problem Solving Overview SR1202 enclosures include a processor and associated monitoring and control logic to enable them to diagnose problems within the enclosure’s power, cooling and drive systems. The sensors for power and cooling conditions are housed within the Power Supply modules. There is independent monitoring for each unit. If a fault is indicated on the Ops Panel, please refer to Table 9.
LEDs • Green LEDs are always used for good or positive indication. • LEDs Flashing Green or Flashing Amber indicate that non-critical conditions exist. • Solid Amber LEDs indicate there is a critical fault present within the module. Power Supply Module LEDs The Power Supply LED states are detailed in Table 7. • Under Normal conditions the Power On LED should be illuminated constant GREEN • If a problem is detected the Module Fault LED will be illuminated constant AMBER. Table 7.
Table 9.
SR1202 RAID Controller Module LEDs The SR1202 RAID Controller Module incorporates the following LED indicators. For details on how to remove and replace a SR1202 RAID Controller Module see section “SR1202 RAID Controller Module” on page 50. Table 10.
Audible Alarm Mute When the Audible Alarm sounds, it may be muted by pressing the Alarm Mute push-button, located on the enclosure front panel. Automatic muting will take place after two minutes if the mute switch is not manually operated. When the alarm is muted it will continue to sound with short intermittent beeps to indicate that a problem still exists. It will be silenced when all problems are cleared. (See also section “Thermal Warnings“ on page 45).
Troubleshooting The following sections describe problems, with possible solutions, which can occur with your SR1202 SAS Enclosure Platform. System Faults Symptom Cause Action 1. The CONTROLLER FAULT LED will illuminate AMBER on the SR1202 module The ESI processor has detected an internal fault on one of the following modules: – PSU – Cooling – SR1202 RAID Controller Replace faulty module as appropriate: – PSU – Cooling – SR1202 RAID Controller 2.
Thermal Control SR1202 enclosures use extensive thermal monitoring and take a number of actions to ensure component temperatures are kept low and also to minimize acoustic noise. Air flow is from front to rear of the enclosure. Symptom Cause Action If the ambient air is cool (below 25 °C) and the fans are observed to increase in speed then some restriction on airflow may be causing additional internal temperature rise.
Dealing with Hardware Faults Ensure that you have obtained a replacement module of the same type before removing any faulty module. ! WARNING If your SR1202 enclosure is powered up and you remove any module, replace it immediately. If the enclosure is used with plug-in modules, dummy carriers or blank modules missing for more than a few minutes, the Enclosure can overheat, causing power failure and data loss. Such use will invalidate the warranty.
Power Supply Modules ! WARNING The SR1202 enclosure must only be operated with two Power Supply modules installed. Removing an AC Power Supply Module ! WARNING Do not remove the faulty Power Supply module unless you have a replacement unit of the correct type ready for insertion. The system must not be operated without both PSUs in place. As there should always be two power supply units installed, you can continue working while replacing the faulty module. 1.
Installing an AC Power Supply Module ! WARNING Do not mix Power Supply modules of different types or makes. 1. Check for damage, especially to the rear connector on the PSU. ! CAUTION Handle the module carefully and avoid damaging the connector pins. Do not install the module if any pins appear to be bent. 2. Slide the module into the enclosure (Figure 35). 3.
