If the Ethernet Link LED is not lit, no network connection is established. 1. Check if the cable is plugged in at both ends. 2. Check the cable and, if neccessary, replace it. If the Ethernet Activity LED is blinking, data is currently being transferred. Each disk has a Drive Status Indicator LED to the left-hand side. If it is lit amber, a drive fault is indicated. The drive status indicator LED on the right-hand side may show the following codes: LED Code Indications 00 Booting firmware 12 Booting ONTAP 11 ONTAP boot complete E1 DHCP failed on both network ports E2 Battery too low E3 Battery broken Each power supply has two LEDs on the rear side. –A green blinking LED indicates that the power supply is on stand-by voltage. – An amber lit LED indicates a power supply fault. On the rear side, two LEDs are found next to each Ethernet port. If only one LED is lit, no connection is established. If the LED on the NVRAM card is lit amber, a fault is indicated.

If the Fault LED is lit amber, the system is halted, or an error is indicated. A blinking Controller LED indicates activity of the controller. A corresponding Power LED and a Fault LED are also located on the rear side of the system. On the rear side, next to the Ethernet ports, two fault-indicating LEDs can be found. – NVRAM Battery LED blinking green: NVRAM is in battery-backed standby-state (contains data not written to disk yet). – Controller Module Status LED lit amber: System is initializing or system fault. 7.3.3 Disk Shelves There is a corresponding LED next to each SFP slot on the rear side of the shelf: – LED lit green: SFP connection. – LED not lit: No SFP connection. Check all cable connections and ensure all plugs are properly fitted. Bosch Security Systems Installation Guide V 1 | 2008.08 28 en | Monitoring and Maintenance DSDA iSCSI Disk Array Series There are four LEDs on the power supply unit on the rear side of each shelf. If either the Fan LED or the Power LED are lit amber, the power supply unit must be replaced. At the front side of each disk drive, there are two LEDs. – If no LED is lit, the drive is not recognized. Reinsert the drive. – If one LED is lit amber, a fault is indicated. The drive must be replaced. Software Update i NOTICE! Only Bosch certified software can be used. i NOTICE! To update the software, the system must reboot. During this process, no data can be written to the system. i NOTICE! If you are not using VRM, you need a program that functions as a Web server. For example, you can use AIDeX Mini-Webserver which can be downloaded from V 1 | 2008.08 Installation Guide Bosch Security Systems DSDA iSCSI Disk Array Series Monitoring and Maintenance | en 29 1. Upload the new software to a Web server – If you are using VRM, place the file that contains the new version in C:\Program Files\Bosch\Video Recording Manager\VRM Server\web on your VRM Server. – If you are not using VRM, start a Web server tool, for example MiniWebServer.exe, select a root directory and copy the new software version into this root directory. Example screen: 2. Download and install the new version on the storage controller hard disks: Connect to the console of the storage device.
