Introducing the Deskside
Expansion Pedestal
This chapter is an introduction to the BA346–KB series deskside expansion pedestal,
commonly referred to as the “pedestal.” This description includes the options, components,
power and cooling requirements, StorageWorks building blocks (SBBs), and specifications.
1.1 Product Description
The standard BA346–KB deskside expansion
pedestal (pedestal) shown Figure 1–1 is an
enclosure for creating a user-defined storage array
using the small computer system interface (SCSI)
bus. The following are the features of this
pedestal:
• Single-ended, 8-bit or 16-bit, SCSI–2 bus
• Capacity of seven, 3.5-inch SBBs
• 68-pin, high-density input and output
connectors
• ac power supply (switch selectable input
50 to 60 Hz, 115 to 240 V ac)
• Cooling fan
• Jumper selectable SCSI address configurations
• Active SCSI bus termination
To expand the number of devices on a 16-bit SCSI
bus you can interconnect the pedestals providing
you do not exceed the SCSI bus length limitations
listed in Chapter 3.

1.2 Options
You can install the following options in a pedestal either individually or in combination:
BA35X–AA 5.25-Inch Device Option Kit
This kit contains a modular carrier, the cables, and the mounting hardware for installing
either two half-height, or one full-height, 5.25-inch storage device in the top of the
pedestal. This option increases the total number of devices on a 16-bit bus to nine.
See StorageWorks Solutions BA346–KB Deskside Expansion Pedestal 5.25-Inch Device
Installation Guide for detailed information about installing and configuring this option.
BA35X–AB Dual-Bus Option Kit
With the cables and connectors in the dual bus option kit you can split the backplane bus
into two buses—a four device bus and a three device bus. When used in conjunction with
the 5.25-inch option kit, you can have a six device bus and a three device bus in the same
pedestal.
See StorageWorks Solutions BA346–KB Deskside Expansion Pedestal Dual Bus
Installation Guide for detailed information about installing and configuring this option.
BA35X-VB Stability Option Kit
This kit includes a base that improves the stability of the pedestal. The procedures for
installing the base are described in Section 2.6.
BA35X–YA Factory Configuration Option
When you select this option, the factory:
• Sets the configuration addresses (jumpers W1-W3) as the user specifies.
• Installs the SBBs in the slots the user specifies.
• Sets the SCSI device addresses.
• Installs the 5.25-inch modular carrier option and devices.
• Installs the dual bus option.
• Configures the internal SCSI bus.
• Includes, but does not mount, the pedestal door.

1.3 Major Components
The user is responsible for providing the following components, which are available through
your Digital account representative:
• AC power cord with NEMA 15 connector (see Table 1–3)
• Storage Devices—5.25-inch devices and 3.5-inch SBBs
• SCSI cables (BN21K or BN21L)
Table 1–1 lists the major pedestal components supplied with the basic unit and each option.

1.4 Power
The ac power supply (switch-selectable 115 V ac or 230 V ac input), is located in the rear of
the pedestal as shown in Figure 1–2. Figure 1–3 shows the internal dc power distribution,
Table 1–2 lists the power supply specifications, and Table 1–3 lists the country specific ac
power cords.
