Safety notices and their translations

Safety notices are printed in English throughout this document.

A Danger notice warns you of conditions or procedures that can result in death or severe personal injury.

A Caution warns you of conditions or procedures that can cause personal injury that is neither lethal nor extremely hazardous.

An Attention notice warns you of conditions or procedures that can cause damage to machines, equipment, programs, or data.

For translations of the danger and caution notices, see Expandable Storage Plus 2104 Model DS4 and Model TS4 Translated Safety Notices, SC26-7558. The notices are listed in numeric order based on their IDs, which are displayed in parentheses, at the end of each notice. See the following examples of danger and caution notices for the location of the ID number.

DANGER

An electrical outlet that is not correctly wired could place a hazardous voltage on the metal parts of the system or the products that attach to the system. It is the customer’s responsibility to ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (1)

CAUTION:

Do not insert hands or tools into the opening of the empty space that contained the fan assembly. (1)

Electrostatic discharge (ESD)

Attention: When you handle field-replaceable units (FRUs) and other computer

parts, take these precautions to avoid static damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always touch the computer parts carefully. Hold the cards by their edges or metal

cover. Never touch any exposed circuits.

v Prevent people who are not correctly grounded from touching computer parts.

v Before you install a new part, touch the static-protective package that contains

the part against an unpainted metal part of the 2104 Model DS4, 2104 Model TS4, or host system for at least 2 seconds. This reduces the static electricity in the package and in your body.

v Remove the part from its package and, if possible, install it directly into the 2104

Model DS4 or Model TS4 without putting the part down. If you must put the part down, follow these steps:

1. Place the static-protective package that contained the part onto a smooth, level surface.

2. Place the part onto the static-protective package. Do not place the part directly onto any metal surface.

Safety inspection procedures

The safety inspection procedures describe how to inspect the 2104 Model DS4 or Model TS4.

CAUTION: The 2104 Model DS4 and Model TS4 are designed to be installed by the customer and are certified as customer setup. Make sure that the system or rack into which the 2104 Model DS4 and Model TS4 will be installed is also designed and certified for customer setup. If the 2104 Model DS4 and Model TS4 are not, then they must be installed by a CE. (22)

Inspecting the rack

Refer to your rack installation manual for information about performing a safety inspection on the rack.

viii Expandable Storage Plus 2104 Model DS4 and Model TS4 Operator’s Guide

Inspecting the 2104 Model DS4 or Model TS4

Perform the following safety checks to identify unsafe conditions.

External machine checks

Perform the following external machine checks:

1. Check the chassis for damage (loose, broken, or sharp edges).

1. Check for any non-IBM changes that might have been made to the machine. If

any are present, obtain the “Non-IBM Alteration Attachment Survey” form, number R009, from the IBM branch office. Complete the form, and return it to the branch office.

2. Check the condition of the inside of the machine for:

v Metal or other contaminants

v Indications of water or other fluid

v Fire

v Smoke damage

Check for any obvious mechanical problems, such as loose components.

4. Check any exposed cables and connectors for wear, cracks, or pinching.

2 Expandable Storage Plus 2104 Model DS4 and Model TS4 Operator’s Guide

At the front of a 2104 Model DS4, there are 14 device slots 1. Each slot must contain either a SCSI disk drive module or a dummy disk module. Each disk drive module connects to a backplane, which is mounted vertically about halfway between the front and back of the 2104 Model DS4.

Note: To run input/output (I/O), a minimum of one SCSI disk drive module must be

present in each 2104 Model DS4.

The 14 device slots are divided into two groups of 7 slots. Between the two groups of 7 slots, there is a SCSI bridge card2. The SCSI bridge card assigns the disk drive modules to a SCSI bus, in accordance with the setting of the SCSI bus split switch.

On the back of the backplane are connectors for two fan-and-power-supply assemblies 4 and two SCSI Interface cards3.

The 2104 Model DS4 has either two fan-and-power-supply assemblies, or one fan-and-power-supply assembly and one fan assembly. Either option provides all the necessary power and cooling for the 2104 Model DS4.

Having two fan-and-power-supply assemblies is better than one fan-and-power-supply assembly and one fan assembly because the amount of power required from each power supply is reduced. If one power supply fails, power for the 2104 disk enclosure continues to be supplied by the other power supply.

The SCSI Interface cards 3 connect the host machines to the 2104 Model DS4. These cards contain logic that provides information about what is happening in the 2104 Model DS4 and the status of components within it.

The SCSI Interface cards 3 contain switches that control:

The SCSI Interface cards also contain a rotary switch that sets the ID of the 2104 Model DS4.

Figure 29. SCSI Interface card switches

The SCSI Interface card contains the following switches that are accessible to the operator.

Note: Switch configuration is only valid on the SCSI Interface card-1 and the

configuration on the SCSI Interface card-2 is ignored. Therefore, the SCSI Interface card must be placed in the left side viewing it from the rear in single SCSI Interface card configuration.

autostart switch-1 1

Drive

The disk drive motors are controlled by the combination of this switch and the drive autostart switch-2 2.

When this switch is set to off, and the drive autostart switch-2 2 is set to on, the disk drive motors do not start until you issue a START MOTOR command. The timing sequence of the disk motor startup is under the control of the host system software.

When this switch is set to on, and the drive autostart switch-2 2 is set to off, the disk drives are set to delay motor start mode. The disk motor startup delay time is different for each disk drive and is usually computed by multiplying 12 seconds by its SCSI ID. For example, the disk drive motor of a disk drive whose SCSI ID is 2 starts 24 (2x12) seconds after power is applied to the 2104 Model DS4 or Model TS4.

When this switch is set to off, and the drive autostart switch-2 2 is set to off, the disk drives are set to normal start mode. The disk drive motors start when power is applied to the 2104 Model DS4 or Model TS4.

The effect of both this switch and the drive autostart switch-2 2 being set to on is undefined.

When this switch is set to on, the 2104 Model DS4 and Model TS4 is powered up or down by the DC on/standby switch on a fan-and-power-supply assembly.

Box ID switch 6

This 10-position rotary switch indicates the ID of the 2104 Model DS4 and Model TS4. The operator selects the required setting that the SES Inquiry command and the SAF-TE buffer 1 command can use.

SAF-TE services are not used with RS/6000 or IBM Eserver

SCSI bus split control switch 7

This switch controls the SCSI bus mode. When the switch is off, the enclosure is configured as a single SCSI bus. When this switch is on, the enclosure is configured as a dual or split SCSI bus.

The default logical setting for this switch is off.

Switches 8 and 9 (reserved)

This switch should be off.

Disable ID6 handling switch 10

The SCSI ID6 is automatically disabled and removed from the system when all of the following conditions are met:

v This switch is turned off.

v Two SCSI Interface cards are installed with single bus configuration.

v Two hosts are connected to the 2104 Model DS4 and Model TS4 and

both are powered on.

When two SCSI Interface cards are installed and the 2104 Model DS4 and Model TS4 are configured for single-bus mode, an ID conflict exists if a drive is installed in the slot of SCSI ID 6. The conflict exists because one of the host bus adapter (HBA) SCSI IDs should be set to 6 when using both host ports. Unless the disable ID 6 handling switch is off or the drive is removed from the slot of SCSI ID 6, there will be an ID conflict between the HBA using ID 6 and the drive in the slot of SCSI ID 6.

Removing the drive from slot 6 and replacing it with a dummy carrier eliminates the conflict.

An alternative is to turn off the disable SCSI ID6 handling switch, which continuously applies a SCSI RESET signal to the drive in the slot of ID 6

16 Expandable Storage Plus 2104 Model DS4 and Model TS4 Operator’s Guide

when TERMPWR is present on both JBOD interface cards. While the drive is held in RESET, it releases all bus signals, effectively removing it from the system. The drive in the slot of SCSI ID 6 continuously remains in RESET under these conditions until power is removed and the disable SCSI ID6 handling switch is turned on.

Configuration switch 11 - 18

This switch must always be set to off in a 2104 Model DS4 and Model TS4.
