Overview 1-3
1.1.2 Components
The DS20L system has the following observable components:
Enclosure
Fans
Bezel The system has a removable front bezel.
Power Supply
Storage Bay
CD-ROM Bay
The system enclosure measures 1.75 inches high by 17.5
inches wide by 20.5 inches deep.
There are a total of 11 fans in the DS20L system: five on the
front of the system (connected by cables to the system
motherboard) and six mounted internally. Two of the six
internal fans are located between the hard drive bay and the
PCI card assembly. These are cabled onto the PCI riser.
Another fan cabled onto the PCI riser is located near the I/O
board; and the three visible from the back of the system cool
the power supply.
The DS20L system is equipped with a 275-watt AC power
(typical input power) 100-240 VAC 47-63 Hz power supply.
The system includes a custom mounting kit that allows the
installation of a one-inch-high 80-pin SCA SCSI disk drive.
The system accommodates an optional slimline CD-ROM
drive; its bay is located on top of the storage bay.
1.2 Specifications
This section describes relevant AlphaServer DS20L specifications.
1.2.1 Power Connectors
Figure 1-1 shows the two power connectors for the DS20L enclosure.
The main power connector provides single 12 VDC power (Figure 1-1,
5V standby power. The main power connector pinout is non-standard. There are
several voltage regulators on the motherboard to generate various voltages

required by the system. The disk power connector (

1.2.3.1 Safety
The AlphaServer DS20L power supply must be connected to a properly
grounded, single-phase AC power outlet.
The DS20L (Series EA2014) system meets registered product-safety
certification for the U.S. and Canadian Underwriters Laboratories (UL and
CUL).
1.2.3.2 EMC
Hewlett-Packard recommends the use of high-quality, shielded cables for all
external I/O.
The AlphaServer DS20L (Series EA2014) meets electro-magnetic compatibility
(EMC) requirements for the following:
• Federal Communications Commission (FCC) 47 CFR Part 15 Class A (USA)
• EN 55022:1998 Class A ITE emissions requirements (EU)
• EN55024:1998 immunity requirements (EU)
Overview 1-7
• VCCI Class A ITE (Japan)
• AS/NZS 3548:1995/ Class A ITE (Australia)
• CNS13438 Class A (Taiwan)
• The DS20L is designed for professional use in cluster applications. DS20L
clusters deployed in European Community (EC) countries must be
configured with a minimum of four (4) DS20Ls to meet the requirements of
EN61000-3-2. Hewlett-Packard has certified and labeled the DS20L as
European Conforming (CE) compliant based on the minimum four (4) node
installation requirement.
1.2.3.3 Thermal
The DS20L system is designed with a high-performance cooling system to
maintain internal component temperatures within desired operating ranges.
Proper operation of the cooling system requires that the front of the enclosure
receives an adequate supply of air. If the system is installed behind a grill or
other obstruction, it should be no more restrictive than the standard bezel:
approximately 50% open with no shadows. Table 1–2 lists all relevant
environmental requirements.
1.2.4 Physical
Table 1–3 gives the physical dimensions of the AlphaServer DS20L.

Length 20.5 in / 52 cm
Width 17.5 in / 44.5 cm
Height 1.75 in / 4.5 cm (1U)
Weight 21 lbs / 9.4 kg
1.2.4.1 I/O
The rear-panel connectors are integral to the AlphaServer DS20L chassis. The
system uses a custom I/O board to provide connections for two serial ports, one
parallel port, and two Ethernet RJ45 ports.
The DS20L external rear-panel connectors are shown in Figure 1-5.
