CHAPTER 1: Introduction Overview Important Mixing of SAS and SATA drives in the same enclosure is only supported in columns, for example, column 1 is all SAS and column 2 is all SATA. Also, mixing of drives of different capacities in the same column is not supported. The Gateway E-842R SAS Enclosure Platform is a 2U (rack space) disk drive enclosure, housing twelve low profile (1-inch high), 3.5-inch form factor hard drives, which can be either: • 3 GB direct dock SAS disk drives, � 3 GB dir

Important If only one controller module is installed, a blank module must be installed in the unused slot. Enclosure chassis The chassis consists of a sheet metal enclosure assembly containing a backplane printed circuit board (PCB) and module runner system. � The chassis front panel

CHAPTER 1: Introduction Operator’s panel The enclosure’s front panel has an integrated operator’s (Ops) panel with four LEDs. The Ops panel provides you with a high level indication of the operation of the enclosure. See “Ops panel LEDs” on page 8 for details of the LED status conditions. Caution The Ops panel is an integral part of the enclosure assembly and cannot be replaced separately. To replace the Ops panel, you must replace the entire enclosure. Enclosure replacement should only be pe

www.gateway.com Audible alarms The Gateway E-842R enclosure includes an audible alarm which indicates when a fault state is present. The following conditions activate the audible alarm: � Fan fault � Voltage out of range � Over temperature � Thermal overrun � System fault � Logical Fault � Power supply module fault When the audible alarm sounds, you can mute it by pressing the Alarm Mute button on the front panel. For more information, see “Audible alarm mute” on page 16. The plug-in modules

CHAPTER 1: Introduction Controller module Caution Operation of the enclosure with any modules missing disrupts the airflow and the drives do not receive sufficient cooling. All openings must be filled before operating the enclosure. When only one controller module is installed, a blank module must be installed in the vacant controller module slot at the rear of the enclosure to maintain airflow and ensure correct operation. Important Do not mix Disk I/O modules and RAID Controller modules in

www.gateway.com � An RJ45 10/100BaseT Ethernet port lets you connect the controller to a network to enable out-of-band management and monitoring using the embedded StorView GUI software. Important Only shielded, Cat 5 (or better) cables should be used for connection to the Ehternet port for EMC performance. � There is also an RS232 socket which provides an alternative user interface to the RJ45 connector. Caution Although the RS232 port is similar in appearance to a USB port, it requires a s

www.gateway.com Disk I/O module The expansion enclosure houses one or two Disk I/O modules. They provide the drive expansion for the RAID enclosure. When expanding the system, you may add up to four expansion enclosures. This will give you a total of five enclosures including the RAID enclosure. A fully loaded system will provide a total of 60 disk drives. Important Do not mix Disk I/O modules and RAID Controller modules in the same enclosure. Disk I/O modules are only installed in the expan

CHAPTER 1: Introduction Drive carrier module The drive carrier module comprises a hard disk mounted in a carrier. Each drive bay houses a single, low profile, 1.0-inch high, 3.5-inch form-factor disk drive in its carrier. The carrier has mounting locations for SAS or SATA drives. The front cap also supports an ergonomic handle which provides the following functions: � Inserting the carriers into the drive bays � Removing the carriers from drive bays � Positive “spring loading” of the drive/bac
