Installation order of physical disk groups Physical Disk Slot Number 1 1 – 14 2 43 – 56 3 15 – 28 4 57 – 70 5 29 – 42 6 71 - 84 From the table, we understand that the first 14 physical disks must be placed in slots 1–14 and the next 14 physical disks must be placed in slot 43–56.
Steps 1 Each row with drives installed must be filled entirely (14 drives). 2 Top and bottom drawers must have rows filled evenly; within a count of 1. Refer to Installation order of physical disk groups table listed in Physical disk installation guidelines 3 All spinning drives in the same row must be the same rotational speed. 4 An individual row can have spinning drives with a different rotational speed than another row. 5 Spinning drives and SSDs can be mixed within a row.
2 Installing and removing system components This section describes the tasks to replace field replaceable units (FRUs) inside the Dell Storage MD1280 enclosure. Here, it is assumed that the user has already received the appropriate replacement device and is ready to install the device in the enclosure.
General safety precautions To avoid injury and damage to an enclosure, always follow general safety precautions. WARNING: Do not lift the enclosure without any assistance. If installed above the lower 20U of a rack, a customer‐provided mechanical lift must be used to avoid injury. • Keep the area clean and free of clutter around the chassis.
Identifying the failed PSU To identify a non-functioning PSU, use the secli component of the Storage Enclosure Management Software or visually verify which PSU is not functioning. Replacing a PSU About this task To replace failed PSUs, complete the following tasks: Steps 1 Turn off the PSU switch. 2 Remove the power cord from the securing clip and then remove the power cord from the PSU. 3 Push the red release tab to right and hold it, and then slide the PSU out of the chassis by using the PSU handle.
Figure 9. Securing the power cord 1 7 Power cable securing clip Turn on the PSU switch. NOTE: Allow the enclosure to identify the PSU and determine its status. If the PSU is functioning properly, the PSU’s Power OK LED glows green and the PSU fault LED and AC fault LED are off. Replacing fan modules The Dell EMC Storage MD1280 enclosure supports five fan modules. If one fan module fails, the remaining modules continue to cool the enclosure.
Figure 10. Removing a fan module 1 Fan module 2 Release tab 2 Rotate the replacement fan module so that the release tab and handle are on the right side. 3 Slide the replacement fan module into the chassis until it is fully seated and the release tab clicks into place. NOTE: Allow the enclosure to identify the fan module and determine its status. If the fan module is functioning properly, fan module’s Module OK LED glows green and the battery fault LED and fan fault LED are off.
Figure 11. Numbering hard drive 1 Drive drawer 1 2 Drive drawer 0 Identifying the failed hard drive To identify the failed hard drive, use the secli component of the Storage Enclosure Management Software or visually verify the failed hard drive. Replacing hard drives About this task Hard drives can be replaced one at a time without turning off the enclosure.
Figure 12. Opening DDIC 1 Drive drawer latches (2 per drawer) 2 Drive drawer CAUTION: Before opening a drive drawer, ensure that the system is not indicating a temperature warning. This issue must be rectified first to avoid potential hard drive failure and data loss. 2 Push and hold both red drive drawer latches toward the center of the drive drawer and pull out the drive drawer.
Figure 13. Removing DDIC 7 1 Hard drive fault LED 3 DDIC 2 Release button Slide the replacement DDIC into the slot, push and hold the DDIC down while sliding it toward the back of the enclosure until the DDIC latches to the backplane. CAUTION: If the DDIC fails to latch, do not use it and request a replacement. If a faulty DDIC unlatches within a closed drive drawer, then you cannot open the drive drawer.
Figure 14. Closing drive drawer 1 8 Drive drawer 2 Open-drawer lock Close the drive drawer. a b Pull and hold both drive drawer releases, and push the drive drawer inside slightly. Release and push the drive drawer until it clicks into a place. WARNING: After releasing the open‐drawer locks, move hands away from the slides to avoid injury while pushing the drive drawer inside. NOTE: Allow the enclosure to identify the hard drive and determine its status.
Replacing an EMM About this task EMMs can be replaced one at a time without turning off the enclosure. To replace failed EMMs, complete the following tasks: Steps 1 Remove all cables from the EMM. Ensure all the cables are labeled. 2 Push the release tab to right and pull the release lever away from the chassis. 3 Grasp the release lever and pull the EMM away from the chassis. Figure 15. Replacing an EMM 1 EMM 4 Insert the replacement EMM into the bay until it is fully seated.
b Remove the HDBs from the rear of the rack. 2 Remove all DDICs from the enclosure and place on a static free mat or bench. Note the slot position of each DDIC as you remove it, the DDICs must be reinstalled in the same slot position as in the original chassis. 3 Remove the enclosure from the rack rails. WARNING: Do not attempt to lift the enclosure without any assistance. If installed above the lower 20U of a rack, a customer‐provided mechanical lift must be used to avoid injury.
Steps 1 Insert the power cords. 2 Press the power button on the enclosures to turn on the power. NOTE: Always turn on the enclosures before turning on the host. 3 Ensure that the host is turned on. 4 Use the secli component of the Storage Enclosure Management Software to verify that the replacement device is up and running. 5 Install all available firmware update by using secli.
3 Troubleshooting Dell Storage MD1280 components This section contains basic troubleshooting tasks for components inside the Dell Storage MD1280 enclosure. Topics: • Troubleshooting fan modules • Troubleshooting PSUs • Troubleshooting DDICs • Troubleshooting I/O EMMs Troubleshooting fan modules About this task To troubleshoot fan modules, complete the following tasks: Steps 1 Determine the status of the fan module LEDs. If the fan fault LED glows, the fan module has failed.
Steps 1 Determine the status of DDIC LED. 2 a If the DDIC fault LED glows, the hard drive has failed. b CAUTION: Confirmed that the particular hard drive contains no user data. The Fault LED alone is not an indication the hard drive can be safely removed. If the DDIC fault LED is not glowing, perform step 2. Check the connectors and reseat the DDIC. CAUTION: This task should be only performed on unmanaged hard drives or after it is confirmed that the particular hard drive contains no user data.
