1 Introduction 4 Features • Fourteen disk drive slots. • Redundant AC power supplies. • Redundant input power cords. • A total of four fans in two Advanced Cooling Modules (ACM) providing n+1 redundancy on fans. • Two rear removable I/O option modules provide active/passive failure redundancy on env...

1 Introduction 6 Cooling system Cooling is provided by the two Advanced Cooling Modules (ACMs) located at the rear of the enclosure. Each of the ACM units contain two variable speed fans. The enclosure requires four fans for normal operation, but will operate correctly when one fan fails to function...

7 I/O modules There are two I/O option slots located at the rear of the enclosure. One of these must contain an Enclosure Services Module (ESM) or a Concentrator Services module (CSM) and the other slot must contain the Terminating Services Module (TSM) or a second Concentrator Services Module (CSM)...

1 Introduction 8 Terminating Services Module The Terminating Services Module (TSM) has no external connectors and as such cannot have cables connected to it. Instead it can either terminate or join the SCSI busses based on the cable configuration on the ESM. The TSM reports status and receives contr...

Dual concentrator services modules Four host cables are required for this configuration. These cables must not exceed 25 meter...

3 Cabling and configuration 30 Join/Split bus jumper The ESM/CSM has a jumper located on it that forces the SCSI bus into joined or split mode. This jumper is located on the ESM/CSM PCB at location JP10. To access the jumper: 1. Remove the ESM/CSM from the enclosure. 2. Remove the top cover from the...

31 Powering on the Altos S300 series enclosure This section describes how the Altos S300 series enclosure is powered on. 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 j...

3 Cabling and configuration 32 Delayed Start If you select this option, the disk drives will spin up sequentially i.e. not all together. 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...

35 Overview The Altos S300 series enclosure uses LEDs and an audible alarm to report the enclosure status. The LEDs are located on the enclosure modules such as the disk drive carriers, Advanced Cooling Modules (ACM), power supply modules, and enclosure front LED panel. The enclosure status is monit...
