[. . . ] Follow the procedures below to connect the cables (see figure on page 24): 1. Attach one end of the second cable to the second connector on the ESM. Attach the other end of this cable to a host. Note: For more information on the host connectors, refer to the documentation supplied with the host system. 1 Enclosure must be powered on to see the LEDs. 24 3 Cabling and configuration To Host ID 7 To Host ID 7 1 2 1 2 Mute 0 ESM I I 0 TSM The ESM and TSM can be in either I/O slot of the enclosure. SCSI ID Assignments shown from front of enclosure. The Bus A LED2 will be on for top connector to indicate that first seven disks are on Bus A. The Bus B LED will be on for bottom connector to indicate that remaining seven disks are on Bus B. The Environmental Services (ES) LED is ON for both the ESM and TSM, to show that both of their ES blocks are active. Note: Both I/O modules are at ID 15. For information on the I/O module LED, see page 20. 2 Enclosure must be powered on to see the LEDs. 25 Single CSM and TSM Configuration This configuration can be cabled as either a Single (Joined) SCSI Bus or as a Dual (Split) SCSI Bus configuration. Cabling the single (joined) SCSI bus configuration One host cable is required for this configuration. When viewed from the rear there should be a CSM installed in one I/O slot and a TSM in the other. Follow the procedures below to connect the cable (see figure below): 1. Attach the other end of this cable to the host. To Host ID 7 1 2 1 2 Mute 0 CSM I I 0 TSM The CSM and TSM can be in either I/O slot of the enclosure. SCSI ID Assignments shown from front of enclosure. Note: For information on the host connectors, refer to the documentation supplied with it. 26 3 Cabling and configuration The Bus A LED will be ON3 to indicate that all disks are on Bus A. The Environmental Services (ES) LED is ON for the TSM in this example to show that its ES block is the active block. Note: Both I/O modules are at ID 15. Only one module will be active at any one time and the other will be on standby. Jumpers installed on the I/O modules determine how the enclosure powers up and how the disk drives spin up. The following section describe the jumper settings. Altos S300 series jumper settings The Altos S300 series enclosure jumpers are located on the I/O Modules (ESM and CSM). By installing or removing these jumpers the following options may be set. Note: For information on the I/O module LED, see page 20. Power up With this option enabled, the enclosure will power up automatically when the host system is powered on. Switch on the enclosure (switches on PSU's at rear of enclosure). Power on the host system and the enclosure will power on also. To disable this option, install a jumper at location JP13 on the ESM and CSM (whichever is installed). If two CSMs are installed, the jumper should be installed on both CSMs. Remote start up If you select this option, the disk drives will not spin up until a spin up command is issued by the host system (even though the enclosure is powered on). To enable this feature, install a jumper at location JP12 on the ESM and CSM (whichever is installed). If two CSMs are installed, the jumper should be installed on both CSMs. 32 3 Cabling and configuration Delayed Start If you select this option, the disk drives will spin up sequentially i. e. To enable this feature, install a jumper at location JP11 on the ESM and CSM (whichever is installed). If two CSMs are installed, the jumper should be installed on both CSMs. Powering on an AC enclosure 1. Ensure all cables have been attached as described in the preceding sections. [. . . ] Es wird empfohlen, die Installation des Laufwerkfachs von mindestens zwei Personen vornehmen zu lassen. Försiktighet: När en utrustningshylla installeras eller avlägsnas ska all strömtillförsel bortkopplas och alla skivdrivenheter avlägsnas. Det rekommenderas att du arbetar med minst en person till när en skivhylla ska installeras. Detta är nödvändigt för att förhindra personliga skador och skador på hyllan. [. . . ]
