Introducing the SA7x Enclosure

This chapter is an overview of the SA7x enclosure, lists SA7x conﬁgurations and speciﬁcations, and discusses user precautions.

1.1 SA7x Enclosure Overview

The term ‘‘SA7x’’ refers to the family of enclosures that includes:

• The SA70—Accommodates one to four RA70 disk drives (280 MB each)

• The SA71—Accommodates one to four RA71 disk drives (700 MB each)

• The SA72—Accommodates one to four RA72 disk drives (1 GB each)

• The SA73—Accommodates one to four RA73 disk drives (2 GB each)

For all of these designations, the enclosure itself is physically identical. What differentiates an SA70 enclosure from an SA71 enclosure is the type of drives installed in each (RA70s and RA71s). See Figure 1–1 for an illustration of an SA7x enclosure.

Table 1–1 lists the the types of disk drives that are authorized for installation in each SA7x enclosure.

Table 1–1 Authorized Disk Drive Installations

Enclosure RA70 RA71 RA72 RA73

SA70 Yes No No No SA71 Yes Yes Yes Yes SA72 Yes Yes Yes Yes SA73 Yes Yes Yes Yes

A maximum of three drives may be installed.

The SA7x enclosure provides mounting space, power, cooling, and control for up to four RA7x disk drives. Each disk drive is independently powered and operated by the enclosure.

The enclosure is installed as a component in a storage array cabinet. The RA7x disk drive used in the SA7x enclosure is a random-access Winchester

technology drive with a formatted storage capacity of 280 MB to 2 GB. The drive features modular components that can be replaced with minimum down time. Figure 1–2 shows an RA70 disk drive. Figure 1–3 shows an RA71 through RA73 disk drive.

You can combine SA7x enclosures into shadow sets. When using shadow sets, remember that when replacing the power supply or transition boards 1 or 2, you need to remove the power from the enclosure.

RA7x disk drive can be used with any disk drive controller using a standard disk interface (SDI), including KDA50, KDB50, or KDM50 controller modules, hierarchical storage controllers (HSCs), and UDA controllers. The drive is compatible with the Digital Storage Architecture (DSA) and Mass Storage Control Protocol (MSCP).

1–4 Introducing the SA7x Enclosure

Introducing the SA7x Enclosure

1.1 SA7x Enclosure Overview

The major subassemblies of the SA7x enclosure are:

• Chassis

• Frame

• Operator control panel (OCP)

• Transition board 1 (TB1)

• Transition board 2 (TB2)

• Power supply

• Fan assembly

• Enclosure-internal cables

Figure 1–1 shows the major subassemblies of the SA7x enclosure. Except for the RA70 disk drive description, Figure 1–1 is accurate for all SA7x enclosures.

The frame slides into the chassis and contains the mounting facilities for the other subassemblies. The disk drives ﬁt into recesses located in the front and rear of the frame. The OCP is mounted above the front disk drives and plugs into TB1. TB1 interfaces the OCP to TB2. TB2 is located above the front disk drives and interfaces drive signals through TB1 to the OCP. The power supply is located in the rear of the frame, below the rear disk drives. The fan assembly is ﬁtted into the central portion of the frame. Interconnecting cables for the subassemblies run along the outer sides of the frame behind acoustic paneling.

RA7x disk drives may be mounted in any of the four disk drive positions. Installation procedures suggest to install the ﬁrst two drives in the rear positions and the second two drives in the front positions.

Caution

The SA7x enclosure will accommodate a single RA7x disk drive. However, if only one drive is installed in the enclosure, a drive position ﬁller is required to route cooling air and prevent overheating. See Section 3.2 for instructions on installing and removing a drive position ﬁller.

The disk drive is installed in an enclosure with the rear panel of the drive, which contains interface connectors, facing outward. The drives are operated from four sets of switches and indicators on the enclosure OCP, one set for each disk drive in the enclosure.

SDI bus cables from the disk drives are routed inside the enclosure to a cable bulkhead at the top rear of the enclosure.

The enclosure power supply provides operating power to the major subassemblies of the enclosure. The rear panel of the power supply contains the Master On/Off switch for the enclosure.

Each RA7x disk drive is powered and controlled independently. A drive can be operated with other disk drive positions unoccupied or while maintenance is being performed on another drive. The power switches for the disk drives are located on the front panel of the enclosure. Each drive power switch contains a symbol to indicate its associated drive and an indicator that lights when power is applied to the drive.

Introducing the SA7x Enclosure

1.1 SA7x Enclosure Overview

The fan assembly circulates cooling air throughout the frame of the SA7x enclosure. The air is drawn in through holes in the front panel on the enclosure and is exhausted through holes in the rear panel.

The SA7x enclosure meets the following environmental and safety standards:

• DEC Standard 102 for environment

• DEC Standard 103 for electromagnetic emissions

• DEC Standard 104 for computer room noise level

• DEC Standard 119 for product safety

• National and international regulatory agency requirements, including FCC, UL, IEC, CSA, and VDE

1.4 User Precautions

Digital recommends that certain precautions be taken to protect equipment and user data. These precautions involve backup methods, recommended operating temperatures, and electrostatic discharge (ESD) protection, all of which are discussed in this section.

1.4.1 Data Recovery

Data is not recoverable from an inoperable head disk assembly (HDA). Therefore, it is your responsibility to make sure data is protected using proper backup procedures. Digital recommends the following backup methods for RA7x disk drives:

• File duplication—This method normally involves copying data onto removable media, such as magnetic tape.

• Journaling—This method is recommended for ﬁles in a transaction processing application. Journaling allows reconstruction of ﬁles up to the last checkpoint or backup.

1–10 Introducing the SA7x Enclosure

1.4.2 Recommended Operating Temperature

The SA7x enclosure and its installed drives can operate within a temperature range of +10° to +40° C (+50° to +104° F). However, Digital recommends that the enclosure and its drives be operated in a temperature range of +18° to +24° C (+64° to +75° F) to increase reliability and product life.

Caution

Disk drives and enclosures must be environmentally stabilized in their protective barrier bags at the installation site. Failure to environmentally stabilize the equipment may result in damage to the drive media or electronic components. For more information about environmental stabilization, see Appendix A.

1.4.3 Electrostatic Discharge Protection

Electrostatic discharge (ESD) is caused by the buildup and release of static electricity. An electrical charge from a person or object can damage hardware components and result in premature device or option failure.

Observe the following guidelines when handling static-sensitive components:

Introducing the SA7x Enclosure

1.4 User Precautions

1. Read all instructions and installation procedures included with static control materials.

2. Wear a properly grounded ESD wrist strap. (See Figure 1–4.) When using an ESD wrist strap:

• Ensure that the wrist strap ﬁts snugly for proper conductivity.

• Connect the alligator clip securely to a clean, unpainted, grounded metal

surface, such as the drive or cabinet chassis.

• Do not overextend the grounding cord.

3. Use static-protective containers to transfer modules and components.

This chapter describes the SA7x enclosure’s front and rear panel switches and indicators and explains how to use them. It also explains how to apply power to the enclosure and how to place drives on line and off line.

You must be a qualiﬁed Digital Multivendor Customer Services engineer to perform procedures that involve the drive power switches or internal storage array cabinet switches and indicators.

2.1 SA7x Switches and Indicators

The SA7x switches and indicators are located on both the front and rear panels. The front panel contains the operator control panel (OCP) and the drive dc power switches. The rear panel contains the power supply related switches and indicators. Figure 2–1 shows the SA7x enclosure front panel. The OCP is located along the top enclosure and contains the Unit Select switch and four identical sets of switches and indicators. Each set of switches and indicators is dedicated to one of the four disk drive positions in the enclosure. Drive power switches and indicators for the four disk drive positions are located at the bottom.

Operating the SA7x

Note

The switch and indicator set for each disk drive position is operational ONLY when the disk drive is powered up.

2.1.1 Using the Switches and Indicators

Table 2–1 is a summary of SA7x control and indicator functions. Table 2–2 is a detailed description of OCP control and indicator functions. The following general comments are also applicable:

• During power-on and spin-up of a drive, the OCP switches and indicators have slightly modiﬁed meanings, as described in Section 2.4.1.

• The control set for each disk drive position contains Ready and Unit Number indicators and switches for run operation, fault conditions, write protection, unit number selection, and A/B port selection.
