To daisy chain enclosures together, connect link cables from the bottom connectors on the I/O modules of the first enclosure to the top connectors of the I/O modules on the next enclosure (see Figure 3-3). Note: A maximum of eight enclosures may be daisy chained together.

Caution: When daisy chaining enclosures, you must ensure that each enclosure has a unique Enclosure ID. Quad Loop Configuration Note: Quad loop configuration requires that the enclosure be configured in split loop mode. To set split loop mode, a jumper must be installed at jumper location JP3 on each LS module in the enclosure. 36 Chapter 3 JBOD Configurations This section describes the procedure for connecting the enclosure in quad loop mode. For this configuration there must be two LS modules and two I/O modules installed in the enclosure. 1 Remove both LS modules from the enclosure and install a jumper, at jumper location JP3 if one is not already installed. This sets the enclosure to operate in split loop mode. Attach cables to the top and bottom connector of both I/O modules (see Figure 3-4). 2 3 Attach the other end of these four cables to your host systems.

Only one power supply is required for normal operation. However, a second, optional power supply may be added to provide a redundant power system. Each power supply has its own AC power inlet. Caution: Power supply cords shall have conductors with a crosssectional area not less than 4mm2. This cross-sectional area corresponds to a minimum 10AWG wire. Connecting an AC Power Source 1 2 Ensure all cables have been attached as described in the preceding sections. Attach the AC power cords to the power supplies and turn the power supply switches to the On (-) position (see Figure 3-5).

Ensure the power cabling provides earthing continuity to the equipment. I 0 I 38 Chapter 3 JBOD Configurations Disk Drive Spin Up Sequence At power on, the LS module will perform its internal start up initialization routine. Then the LS module will assert the disk drive START_1 and START_2 motor start signals low for disk drive slots 7 through 13, which will spin up the first 7 disk drives immediately. The LS module will then assert the disk drive START_2 motor start signal low and leave the START_1 motor start signal high for disk drive slots 0 through 6 which will command the second seven disk drives to spin up after a delay of 12 seconds times the modulo 8 value of the numeric SEL_ID of the disk drive. Once the enclosure is powered up and all 14 drives are spun up as depicted above, the enclosure will support immediate drive spin up with two power supplies present. Modulo 8 The drive spin up sequence above uses modulo 8 to calculate the spin up delay. Modulo 8 is determined by: (SHELF ID x DRIVE NUMBER)/8 = NUMBER + REMAINDER It is the REMAINDER value that is used for the calculation as it is always between 0 and 7 (hence modulo 8). The drive spin up time can then be calculated as follows: REMAINDER x MODE PAGE SETTING = SPIN UP DELAY (Seconds) EXAMPLE: A typical Mode Page Setting is 12, so if the Remainder = 7, the Spin Up Delay would be 7 x 12, or 84 seconds. Chapter 4 RAID Configurations This chapter describes how to set up, configure and use the Altos S700 Series RAID Controller. Some general information about the RAID controller is also provided. 41 Altos S700 Series RAID Controller Introduction The Altos S700 RAID Controller is a high performance controller, providing two host fibre channel and two device fibre channel interfaces. It is an intelligent, caching controller that supports RAID levels 0, 1, 3, 5, 0+1, and JBOD.

Im Bereich des Lüftungsanschlusses besteht Stromschlaggefahr. Det finns risk för elstötar i området runt fläktanslutningen. Tuuletinliitännän ympäristössä voi olla sähköiskun vaara. Der er fare for stød i området, hvor ventilatoren er tilsluttet. Det kan være en viss risiko for elektrisk støt i nærheten av tilkoblingspunktet for viften.
