- Industry standard 3.5 and 5.25-inch form factor devices
- Power supplies and Battery Backup Units
• Fan assemblies (blowers)
• Personality module
Figure 1–2 identifies the components of the StorageWorks Wide Expansion Storage
Pedestal configured with a 5.25 and two 3.5-inch disk drives.
1.3.1 StorageWorks Building Blocks (SBBs)
All storage devices and power units are mounted inside modular carriers that plug into
slots in the pedestal. Each SBB can be removed and replaced without powering down the
pedestal. In addition, each SBB has visual status indicator LEDs which are used to
determine whether devices are functioning properly.
The 3.5-inch SBB enclosure has guides that mate with grooves in the pedestal slot and
ensure that the connector at the rear of the enclosure properly mates with the pedestal
connector. When the SBB is fully inserted into the pedestal, the side mounted tabs
expand and engage the pedestal to securely mount the SBB. To remove the SBB, you
1–2 Order Number: EK–SMCPC–UG. A01
Chapter 1. Introduction
press and hold the two mounting tabs and slide the device out of the pedestal. 5.25-inch
SBBs require three pedestal slots for mounting. There are guides that mate with the
grooves in the pedestal to ensure that the connector at the rear properly mates with the
pedestal connector. The insertion and removal of the 5.25-inch SBB is the same as the
3.5-inch device described above. The 5.25-inch SBB contains a switchbank at the rear of
the unit to set the SCSI address of the device manually. If not used, the SCSI address is
set automatically to the pedestal's slot number.
1.3.2 Blower Unit
The StorageWorks Wide Expansion Storage Pedestal contains two dual-speed blowers
for cooling purposes. The blowers are mounted at the rear of the pedestal and obtain their
power through a connector on the backplane. The blowers are secured by two "press-torelease" mounting tabs and a single screw in the corner of each blower unit. The blowers
normally run at the lower speed. If one of the blowers fails, the second blower
automatically goes to the higher speed. An LED on the front of the personality module
goes out, indicating the failure of one blower. This dual-speed operation prevents
overheating of the storage device.

Order Number: EK–SMCPC–UG. A01 1–3
StorageWorks Wide Expansion Storage Pedestal
1.3.3 Personality Module
The personality module, shown in Figure 1–3, is located above slot 0 where it plugs into
a male connector on the backplane.
Refer to Chapter 3 for detailed information on the SCSI bus
configurations mentioned below.
Input SCSI bus connector JA1 is a 68-pin female connector that mates with a right-angle
connector on the SCSI bus cable from the host.
SCSI bus connector JB1 is also a 68-pin female connector. In a single bus configuration
with one pedestal, JB1 is not used and the personality module automatically terminates
the SCSI bus
.
Connecting JB1 to an open-ended SCSI cable will not disable
the auto-terminator.
NOTE
NOTE
In a two-bus configuration with one pedestal, JB1 becomes the input for the second SCSI
bus. Connecting a SCSI bus to JB1 disables the personality module’s auto-terminator.
Installing a terminator board on the backplane terminates the two SCSI buses.
As detailed in Chapter 4, two LEDs on the personality module indicate the status of the
lower and upper blowers and indicate when an over-temperature condition is detected in
the pedestal.
Seven address switches are set off (down) at the factory and are left off when a single
pedestal is configured for either one or two SCSI buses.

Chapter 1. Introduction
1.3.4 Pedestal Cabinet
The floor-mounted pedestal cabinet is a modular storage cabinet that is completely selfcontained with its own 3.5-inch SBB power supply, two dual-speed blowers, and two
SCSI cable connectors. Refer to Section 3.5.2 for slot assignments when two SCSI buses
are configured in one pedestal. The characteristics of the pedestal are outlined below
(refer to Figures 1–2 and 1–4).
• The capacity of the pedestal is eight 3.5-inch SBBs, one of which must be a power
supply.
• The pedestal slots are numbered 0 through 7 from top to bottom.
• Seven SCSI bus device addresses (target IDs) 0 through 6, associated with the
pedestal slots, can be assigned to either 3.5-inch or 5.25-inch SBBs.
• The slot numbers and the default SCSI device addresses are the same for slots 0
through 6. Slot 7 is reserved for the power supply and does not have a device
address.
• There are two 68-pin, female SCSI connectors on the personality module. The
personality module plugs into the backplane directly above slot 0.
• The ac distribution unit controls prime power (switches) to the power supply
installed in slot 7 and the optional redundant power supply in slot 6. See Figure 1–4.
• Slot 6 can be used for either a storage SBB, a redundant power supply, or a battery
backup unit (BBU).
• The pedestal has two replaceable blowers mounted at the rear.
• The pedestal also has two foam blocks. These blocks ensure proper air circulation
and must not be removed. One block is mounted above the personality module, and
the other is located under the ac distribution unit between the feet of the pedestal.

Installation
This chapter describes the installation procedures required to connect the pedestal to the host, identifies
the SCSI cables and connectors, and contains a power-on test to ensure the pedestal is functioning properly.
2.1 Introduction
This chapter contains a description of SCSI cables and connectors required to connect the
pedestal to the host system. It also describes the power-on test that ensures your storage
pedestal is functioning properly. Information is divided into the following sections:
• Unpacking
• SCSI cables and connectors
• Connecting the pedestal to the host system
• Power-on test
2.2 Unpacking
Before unpacking the storage pedestal or its components, check all packing slips to ensure the correct equipment has been shipped. Also, inspect the shipping containers for
damage (crushed corners, punctures, and so forth). All boxes and packing material
should be retained at the installation site for reshipment, if necessary.
There are two foam blocks mounted in the pedestal that are required for proper air circulation. These must not be removed. One is located above the personality module, and the
other is under the ac distribution unit between the pedestal feet.
2.3 SCSI Cables and Connectors
SCSI connectors are used on the ends of SCSI cables and on connected equipment. This
section discusses:
• SCSI “P” cables
• Storage pedestal SCSI connectors
• SCSI “P” cable communications
Order Number: EK–SMCPC–UG. A01 2–1
StorageWorks Wide Expansion Storage Pedestal
2.3.1 SCSI “P” Cables
The wide expansion storage pedestal uses a host-to-pedestal SCSI “P” cable shown in
Figure 2-1. Table 2-1 and Section 2.3.3 provide more definition. Cable length varies with
application and must be specified when ordering.
Figure 2–1 Host-to-Pedestal SCSI “P” Cable
Table 2–1 SCSI "P" Cables
Cable* Host Connector Pedestal Connector
BN21K 68-pin male, straight 68--pin male, right-angle
* Complete cable designation has two more alphanumeric characters which specify length. For
example, BN21K-01 is a 1-meter (3.3 feet) cable.
2–2 Order Number: EK–SMCPC–UG. A01
2.3.2 Storage Pedestal SCSI Connectors
The pedestal has a SCSI bus in its backplane that supports the SCSI devices that plug
into the slots. The pedestal backplane is preconfigured at the factory with one SCSI bus,
but can be reconfigured to support two SCSI buses if desired. Two SCSI connectors are
located on the personality module which plugs into the top of the backplane. One is used
to connect the pedestal to the host system SCSI adapter; the other is used when supporting two buses or extending a SCSI bus from one pedestal to another SCSI device.
2.3.3 SCSI "P" Cable Communications
The SCSI "P" cable is designed for 16-bit, single-ended communications. Sixteen-bit refers to the 16-bit wide data bus. Single-ended refers to a signal whose level is established
between one wire and ground as opposed to a differential signal whose level is established by the potential difference between two wires.
2.4 Connecting the Pedestal to the Host System
The pedestal-to-host connection procedure consists of installing the host-to-pedestal
SCSI "P" cable between the SCSI connector on the personality module and the SCSI
connector on the host system, and then powering on and verifying the status of SBB
LED indicators to ensure the equipment is operating properly. The information in this
section is divided as follows:
Chapter 2. Installation
• SCSI "P" cable connections
• Power cable connection
• Installing devices
• Pedestal power-on test
NOTE
For fast data transfer, keep SCSI “P” cable lengths as short
as possible.
2.4.1 SCSI "P" Cable Connections
Connecting the pedestal to a host system requires the use of the BN21K cable listed in
Table 2–1. (Specify length when ordering.) The cable can be routed through the rear of
the pedestal behind the bezel, or through one of the four removable filler tabs on each
side of the pedestal at your option. Figure 2–2 is a connection diagram showing the cable
connection between the pedestal and host system. Figures 2–4 and 2–5 show two of the
optional routing paths for the SCSI "P" cable. If a short cable is used, it may be more
convenient to route the SCSI cable from the pedestal to the host directly through one of
the upper rear filler tabs on the left or right side of the pedestal depending on the location
of your workstation. The following procedures apply to a cable long enough to be routed
through the rear, or through one of the filler tabs on each side of the pedestal, at your option.

Maintenance
This chapter describes the status of the SBB LED indicators and how to replace the components in the
pedestal. It also presents a brief troubleshooting approach in the event of a pedestal component
malfunction.
4.1 Pedestal Indicators
The wide expansion storage pedestal identifies error conditions or failures caused by the
major pedestal components such as the blowers, power supplies, or storage devices. This
status is displayed on the power supply and storage device light emitting diodes (LEDs).
The following sections describe the logic signals representing these conditions or failures
(their states and functions) and how to interpret the LED displays.
4.1.1 Pedestal Status
The pedestal monitors both blower operation and power. The blowers on the rear of the
pedestal provide cooling and the pedestal power supply provides +5 Vdc and +12 Vdc to
operate the storage devices. The personality module LEDs monitor blower status. The
power supply LEDs indicate the state of the pedestal components. The LEDs indicate a
fault when one of the following conditions occur:
• A power supply fault
• A blower problem
• An input power problem
4.1.2 Power Supply LEDs
The status of both the pedestal blowers and the power supplies can be determined by the
power supply green LEDs as shown in Figure 4–1. The left LED displays the pedestal
(shelf) status and the right LED displays the power supply status.
• When the left LED is on, both the pedestal blowers and the power supplies are
functioning properly
• When the left LED is off, either a pedestal blower or a power supply is not
functioning properly
Tables 4–1 and 4–2 describe the power supply LED codes.

4.3 Replacing a Power SBB
You need to replace a power supply or battery backup unit (BBU) when the LEDs
indicate a fault condition as outlined in Tables 4–1, 4–2, and 4–3.
The hot-swapping method of replacing a power supply may be used when there are two
power supplies. This method allows you to remove the defective power supply while the
other power supply furnishes dc power to the pedestal.
The input power for each dc power supply is controlled by a switch on the ac distribution
unit. Setting this switch to off removes power from all power supplies in the pedestal. To
remove power from a single power supply, simply disconnect the power cable from that
power supply and remove the unit.
The BBU does not provide power for the operation of a
storage device. It only provides power for protecting data.
4.3.1 Replacing a Primary Pedestal (Non-Redundant) Power Supply
Perform the following procedure to replace a pedestal primary power supply:
1. Power down the pedestal by setting the power switch on the ac distribution to off and
remove the input power cable from the power supply.

4.4 Replacing a Fan Assembly (Blower)
Due to hazardous high-current energy levels present in the
backplane area, use extreme caution while swapping blowers
in the following procedure. Keep all metal objects, including
rings and jewelry, out of the blower/backplane cavity.
To prevent an overheating condition, the replacement blower
should be readily available to ireplace the faulty blower during
the following procedure.
The pedestal has two blowers mounted at the rear. Connectors on the backplane provide
the +12 Volts dc to operate the blowers. As long as one blower is operational, there is
sufficient airflow to prevent an overheating condition. When either blower fails, the left
shelf status LED on the power supply goes off (refer to Table 4–1). Figure 4–6 shows the
removal of a blower.
WARNING
CAUTION
To replace a blower, perform the following procedure:

A.5 Environmental Stabilization
To ensure proper operation of Digital storage devices, the SBB temperature must be
within 18–29° C (65-85° F). Table A–4 specifies the time required to thermally stabilize
SBBs based on the ambient shipping temperature.
Always stabilize storage devices in the operating environment
prior to installation or operation. Otherwise, the media or
associated electronics may be damaged when power is
applied to the unit.
If condensation is visible on the outside of the storage device:
Stabilize the device and the SBB in the operating environment for 6 hours or
until the condensation is no longer visible, whichever is longer. Do not insert the
storage device into the pedestal until it is fully stabilized.
If condensation is not visible on the outside of the storage device:
Thermally stabilize the device for the amount of time specified in Table A–4.

Glossary
This Glossary provides definitions of commonly used terms in the Wide Expansion Storage Pedestal
User's Guide.
ac distribution
The method of routing ac power in the pedestal.
Battery Backup Unit (BBU)
StorageWorks power unit option that extends power availability after the loss of primary ac
power or a power unit, to protect against the corruption or loss of data.
cold swap
A method of device replacement that requires that power be removed from the pedestal, thereby
affecting other devices therein. User applications that are dependent on the devices being
swapped are impacted as a result. This method is used when conditions preclude the use of a hotswap method. Normally, this method is only used when installing or upgrading a StorageWorks
subsystem.
disk
A storage device supporting random access to fixed sized blocks of data.
host
The primary or controlling computer (or any such computer in a multiple computer network) to
which storage is attached.
hot swap
A method of device replacement whereby the complete system remains on-line during device
removal or insertion. Activity may be suspended for a brief period during device insertion or
removal.
SBB
StorageWorks building block. The basic building block of the StorageWorks product line. Any
device conforming to pedestal mechanical and electrical standards, installed in either a 3.5-inch
or 5.25-inch carrier, is considered an SBB, whether it is a storage device, power supply, CPU, or
other device.
