About This Guide
This guide provides information for operating the CHALLENGE™ Vault L
storage box (model no. CMN A014). This product provides additional disk
storage for the Onyx™ and CHALLENGE L (deskside) and XL (rackmount)
systems. The Vault L houses SCSI (small computer system interface) drives.
Each Vault L holds up to eight half-height drives or four full-height drives.
Structure of this Guide
This guide includes the following chapters and appendices:
Chapter 1 “Touring the Chassis” introduces the components visible
from the front and back of the Vault L storage box.
Chapter 2 “Operating the Vault L Storage Box” explains how to install
and remove drives, how to update the system software to
recognize new drives, and how to operate the Vault L
storage box.
Appendix A “Specifications” summarizes technical specifications for the
Vault L storage box.

FCC Warning
This equipment has been tested and found compliant with the limits for a
Class A digital device, pursuant to Part 15 of the FCC rules. These limits are
designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and if
not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at personal expense.
VDE 0871/6.78
This equipment has been tested to and is in compliance with the Level A
limits per VDE 0871.

Chapter 1
1. Touring the Chassis
This chapter discusses the product configurations, and the controls and
connectors visible from the front and rear of the Vault L storage box.
Configurations
The Vault L is available in two configurations:
• differential (which supports differential SCSI drives)
• mixed-channel (which supports both single-ended and differential
SCSI drives)
Note: The “Rear View Components” section tells you how to distinguish
between a differential and mixed-channel Vault L storage box.
The Vault L operates with 8- and 16-bit differential drives and also 8-bit
single-ended drives on the mixed-channel version. However, the Vault L
does not support RAID (random array of inexpensive drive) devices and
also does not currently support 16-bit, single-ended drives.
Warning: This equipment is extremely sensitive and is susceptible to
damage caused by electrostatic discharge (ESD). ESD is an electrical
discharge (spark) caused by the buildup of electrostatic potential on
clothing and other materials.

Chapter 1: Touring the Chassis
Caution: The door must be in place during operation to comply with FCC
regulations and for proper air flow.
On/Off switch controls power to all the drives (see Figure 1-2).
Drive shelves house the SCSI drives and drive sleds. The shelves are
removable to accommodate full-height drives.
Note: Each full-height drive occupies two half-height slots.
Rear View Components
Figure 1-3 shows major components visible at the back of the Vault L
differential storage box and Figure 1-4 shows the rear view of the mixed-
channel configuration.
Note: The mixed-channel version has a connector called SE TERM: A. This
connector is not present on the differential Vault L storage box.

The following major components are located on the back of the Vault L
storage box:
SCSI In (A/B) provides a 68-pin SCSI-2 differential connector.
Note: Each SCSI box provides two SCSI In connectors for disk striping and
increased I/O throughput.
SCSI Out (A/B) provides connection for SCSI termination or a daisy-chain
connection to a second Vault L or another SCSI device.
Voltage Selector Switch
selects between 115 and 230 volts.
Caution: To prevent possible damage to the Vault L, always ensure that the
voltage selection matches the power source input.
Warning: Do not attempt to connect the Vault L to the host system.
Installation should be performed only by Silicon Graphics-certified
personnel.
Installation of these upgrades requires specific training and technical
knowledge. This equipment utilizes electrical power internally that is
hazardous if the equipment is improperly disassembled.
This equipment is also extremely sensitive and is susceptible to damage
caused by electrostatic discharge (ESD). ESD is an electrical discharge
(spark) caused by the buildup of electrostatic potential on clothing and
other materials.
