This chapter covers SCSI device installation for 4-bay 1U rackmount enclosures.

SCA Connection and Hot-Swapping

The unit uses SCA-2 type connectors which provide a safe means of
connection/disconnection when hot-swapping devices. In order to utilize this
feature, the host adapter or RAID controller and host operating software must
support the feature. Any SCA drive is capable of plugging directly into the
backplane of the unit and should not require any additional cabling or
connections.

Canister Removal/Insertion

1. Pull the handle out to unlock the canister from the StorBladeTMunit.
Notice that the locking tab slides down as the handle is pulled out.

2. Pull the canister straight out to remove. Ensure that any installed devices
are spun down before full removal to prevent damage to the drive.

Follow the steps in reverse to reinstall.

Drive Installation

1. After removing the canister, place it on a static free surface along with the
device to be installed.

SAFETY TIP: After disengaging a device from the enclosure, allow 10 seconds

before pulling the canister out of the unit. This allows the device to
properly spin/shut down before transport.

This chapter covers SCSI device setup and option settings. Please take note of the
installation warnings below before beginning setup.

Basic Personality Card Setup

This section covers 4-bay 1U SCSI JBOD units using the basic personality card.
This card does not have a controller interface built-in. The following Figure shows
the slot numbering sequence used to refer to device bays and additionally shows the
factory ID value for each slot. Slots 0-1 are on Channel A and Slots 2-3 are on
Channel B.

WARNING: Take care when connecting the unit to an AC power source to

ensure that it is plugged-in to a circuit of the appropriate rating (110v or
220v). For safe operation, the circuit should have over-current protection
to prevent damage to the unit in the event of circuit overloading.

WARNUNG: Vergewissern Sie sich, daß die Netzspannung (220V / 110V)

korrekt eingestellt ist, bevor Sie das Gerät mit dem Stromnetz verbinden.
Zur Sicherheit sollte das Netz über einen Überspannungsschutz zur
Vermeidung von Schäden im Falle einer Überlast verfügen.

WARNING: When connecting the unit to an AC outlet or power strip, ensure

that the outlet has the proper connection for grounding. The AC power
cables included with the unit have three prongs, one of which is used for
the ground connection. Do not use a two prong AC cable with the unit
since this will not allow for proper unit grounding and could cause
problems with normal unit operation.

WARNUNG: Bei der Verbindung der Unit mit einer Steckdose oder einer

Verteilerdose sollten sie auf eine korrekte Erdung derselben achten. Die
mitgelieferten Kaltgeräteanschlußkabel habe 3 Kontakte, von denen
einer zur Erdung verwendet wird. Verwenden Sie kein Stromkabel mit 2
Anschlüssen, da dieses keine korrekte Erdung ermöglicht und Probleme
während des regulären Betriebs verursachen kann.

Setting ID

The basic personality card has jumpers available on the personality card to set the
ID for each slot. To access the jumpers the top cover must be removed. The
following picture indicates the location of jumpers W1-W4.

There are 4 jumpers on the personality card (W1, W2, W3, and W4) for hard
setting the ID of each slot.

Header W1 is for slot 3
Header W2 is for slot 2
Header W3 is for slot 1
Header W4 is for slot 0

Available ID's

Each bus is allowed to have ID's that range from 0-15. No two devices on the
same bus may share the same ID. Each host controller always uses one ID. The
Figure above shows all 0-15 possible ID settings.

NOTE: View is from rear of the unit.

Switch settings are shown from the rear of the unit.

ID Conflict

When two devices share the same SCSI ID, a conflict occurs. This conflict must
be corrected before the SCSI bus will work properly. If a conflict occurs, check
all jumper settings to ensure that no devices on the bus share the same ID. Also
check all other devices on the bus outside of the enclosure.

Front Status LEDs

A status indicator is located on each canister. A 'Blue' light indicates normal drive
activity . A 'Red' light indicates a device fault. If all canisters display a 'Red' light
that is blinking on and off it indicates that there is a system fault. A system fault
is either a power supply or blower failure. The power supply and blowers are not
field replaceable units. A fault with either the power supply or blowers will
require replacement of the entire unit. Refer to Chapter 5

.

External I/O Connection

The external I/O connections are located on the back of the unit. The figure below
shows the external I/O connections available.

The SCSI In ports are used to connect to a host and require an external cable with
a 68-pin High-Density male connector to mate at the enclosure side. Cables are
not included.

Each SCSI channel must use a separate external cable connection from the
rackmount to the host adapter or RAID controller. It is important that the external
cable length and impedance is taken into consideration and is adequate for the
devices and SCSI speeds being used.

JMR carries its own line of high quality external SCSI Cables.

Termination

Termination must be provided at the end and beginnings of each SCSI bus either
internally or externally. Drive level termination is not recommended since the
terminated device may be easily removed.

Termination is not automatic and the Channel A OUT and Channel B OUT
connections must have LVD/SE termination if not used.

Daisy-Chaining

SCSI I/O Out ports are used to add other enclosures and devices to the SCSI bus.
SCSI I/O Out ports require a cable with a 68-pin High-Density male connector to
mate. When daisy chaining, the SCSI I/O Out port of the enclosure is connected
to the SCSI I/O In port of the enclosure or device being added. Ensure that when
new devices are added to the SCSI bus, that the ID does not have a conflict. Once
the units are connected together, termination must be moved to the last device or
enclosure on the SCSI bus.

6. 1U04 Cabinet Installation

This chapter covers the installation of the Rackmount enclosure into a standard
19" (483mm) wide and 30" (762mm) to 36" (914mm) deep cabinet that meets the
EMA/RETMA standards.

Before beginning rail installation, please take note of the following precautions:

NOTE: When installing the unit into a cabinet or closed environment, the

operating ambient temperature of the rack environment may be greater
than the maximum recommended ambient temperature. Consideration
must be taken to meet the maximum recommended ambient temperature
(Tmra) for the best unit operation.

HINWEIS: Wenn das Gerät in einen Gehäuseschrank oder eine sonstige

geschlossene Umgebung verbaut wird, kann die Umgebungstemperatur
über die maximal zulässige Betriebstemperatur ansteigen. Maßnahmen
bzgl. der maximalen, empfohlenen Betriebstemperatur (Tmra) müssen
getroffen werden, um eine bestmögliche Funktion des Gerätes zu
gewährleisten.

WARNING: Ensure that the front and back of the unit are not blocked when

installing the unit into a cabinet or closed area. Blocking the front or
back of the unit can cause reduced air- flow that will compromise the
safe operating environment within the unit.

WARNUNG: Vergewissern Sie sich, daß das Gerät an Vorder- und Rückseite

nicht abgedeckt ist, wenn das Gerät in einem Gehäuseschrank oder
einer geschlossenen Umgebung verbaut wird. Abdeckung der Vorder­und Rückseite kann verminderte Kühlung zur Folge haben und somit
sichere Betriebsbedingungen negativ beeinflussen.

WARNING: When loading the unit into a cabinet, ensure that a hazardous

condition is not achieved due to uneven mechanical loading. To prevent
injury, remove the power supplies and drives before loading, and re­install them after the unit has been secured in the cabinet.

WARNUNG: Vermeiden Sie während des Einbaus des Gerätes in einen

Gehäuseschrank jegliche gefährliche Aktionen, selbst wenn diese nur
mechanischer Art sind. Um Verletzungen zu vermeiden, entfernen Sie
die Netzteile und Laufwerke vor der Montage und installieren Sie diese
erst erneut, wenn das Gerät im Gehäuseschrank gesichert
ist.Vergewissern Sie sich, daß das Gerät an Vorder- und Rückseite nicht
abgedeckt ist.
