Electrostatic Discharge (ESD) Precautions
When handling any electronic component or assembly, you must observe
the following antistatic precautions to prevent damage. An ESD kit (HP
P/N A3024-80004) is available (or supplied with Memory additions). This
kit contains one wrist strap, one conductive sheet, and one anti-static
foam pad.
• Always wear a grounded wrist strap when working around the
system, and when handling printed circuit boards.
• Treat all assemblies, components, and interface connections as
static-sensitive.
• Avoidworkingincarpetedareasandkeepbodymovementtoa
minimum while removing or installing boards to minimize buildup of
static charge.

General Description
Hewlett-Packard’s SureStore E Carrier-Grade Disk System SC10
(referred to in this guide as the disk system) is a high-availability NEBS
3 certified Ultra2 SCSI storage product. Dual SCSI ports on dual bus
controllers provide LVD connections to the host. Ten slots accept
high-speed, high-capacity LVD/SE SCSI disks connected to a SE
backplane. Data throughput is 40 Mbytes/sec. Eleven disk systems fill a
2-meter System/E rack.
Modular and redundant components are easy to upgrade and maintain.
Disks, fans, power supplies, and bus control cards (BCCs) are replaceable
parts that plug into individual slots in the front and back of the disk
system. Redundant fans, power supplies, and BCCs can be removed and
replaced without interrupting storage operations. Disks also can be
replaced with the system on and with only the affected disks taken
off-line. Hewlett-Packard technical support is optional for these
procedures.
Special electronics and HP-UX software enable remote monitoring and
diagnostics. Sensors on the BCCs monitor the disk system environment,
including temperature, voltage, fan speed, and component status.
Hewlett-Packard’s Event Monitoring System (EMS) reports any changes
in environmental status to user-defined locations, including email
accounts and a system console. Standard HP-UX diagnostic utilities also
report environmental data for enhanced troubleshooting.

Introduction
The following steps are required to install the disk system. This chapter
describes the differences between the installation for theHP SureStore E
Carrier-Grade Disk System SC10 and the standard HP SureStore E Disk
System SC10. The HP SureStore E Carrier-Grade Disk System is a DC
powered NEBS 3 compliant system.
IMPORTANT For NEBS compliance, the product must be installed in a NEBS certified
rack and should have a 1U gap above & below the unit. 2 x 1U filler
panels are shipped with the enclosure to allow for this spacing in the
rack.
For installation of the disk system, you will also need to refer to the
HP SureStore E Disk System SC10 User and Service Guide,aswellas
this addendum. The following task list identifies where to find the
installation instruction for each step of the installation process.

Preparation
Before installing the disk system, make sure:
1. Electrical wiring and breakers meet power needs.
2. The required support software is installed on the host.
Electrical Requirements
All electrical wiring to the service point (plug) must be sized to carry the
following inrush and steady state currents:
CAUTION Adding disk systems to circuits rapidly increases current requirements.
Always make sure that the total current drawn does not exceed circuit
capacity.
CAUTION Thedisksystemmustbefusedtoa19AmpereFusebetweentheDC
power source and the DC power input cable to the DC power supply in
the disk system.

Connect To DC Power
Chapter 218
Connect To DC Power
The HP SureStore E Carrier-Grade Disk System SC10 contains a
NEBS-compatible direct current (DC) power supply, rather than the
alternating current (AC) power supply furnished with the HP SureStore
E Disk System SC10.
This DC power supply directly replaces the standard AC supply for the
purpose of operating this storage device from a central office negative 48
volt or negative 60 volt power source.
The power supply also provides alarm outputs in the form of relay
contact closures to indicate a power supply failure.
WARNING 1.) The power supply cable is used as the main disconnect device
for this equipment.
2.) Make sure that all central office safety precautions are
carefully observed when connecting the power supply to the DC
power source.
3.) This product is to be installed only in Restricted Access Areas
(dedicated equipment rooms, equipment closets or the like) in
accordance with Articles 110-16 to 110-18 of National Electrical
Code, ANSI/NFFA 70.
4.) Installation should be performed only by qualified service
personnel.
CAUTION This product is for DC operation only. Do not install an AC power module
or connect to an AC power source.

Safety Grounding
The HP SureStore E Carrier-Grade Disk System SC10 must be
connected to the central ground in the central office using a minimum 6
AWG (16mm2) wire with a suitable Listed/Certified terminal such as
Thomas and Betts part number 256-30695-1225. A grounding lug and 2
screws are included in the telecom accessory kit (part number
Z7536-60004) provided with the disk system.
Connect the grounding lug to the two grounding PEM nuts inside the
bottom of the chassis, underneath the right-hand power supply.for
connecting to earth ground.
WARNING This equipment must be connected to earth ground to assure
continued safe operation, to prevent damage from electrostatic
discharge, and to assure compliance with electromagnetic
compatibility requirements.

DC Power Cable
The DC Power Cable (Part Number 5065-0096) is a 10 ft. cable consisting
of two parts, a power cable and alarm cable tied together with cable ties.
Strain relief is provided by the clip-on cable connectors. One end of the
cable has connectors for connecting to the disk server power supply. the
other end is terminated in pigtails with the jacket sleeving scored for
removal. Figure 2-2 shows the power cable and connectors. Table 2-2 and
Table 2-3 on page 21 lists the pinouts on the connectors and wiring
information.
