1 hp Carrier Grade Server bh3710 Overview
Introduction
The hp Carrier Grade Blade Server bh3710 (called “blade server” in this manual) provides customers with a
single chassis that houses one server blade and up to four Fibre Channel disks in two dual Fibre Channel disk
carrier blades, controlled by one Management Blade. The form factor for all the blades uses the Compact PCI
standard. The chassis mounts in a standard 19 and/or 23-inch EIA two column rack. The chassis will
accommodate 10 full size Compact PCI cards (6U x 160mm) in the front slots and 10 half size Compact PCI
cards (6U x 80mm), called Rear Transition Modules (RTM), in the rear slots.
Network Equipment-Building Systems (NEBS) Compliance
This system is compliant with NEBS Level 3 requirements as defined in GR63 and GR1089 standards.

2 Unpacking and Installing the hp Carrier
Grade Blade Server bh3710
Introduction
This chapter is intended as a quick reference for blade server installation. Some components and steps may
not apply to all configurations. Steps that do not apply may be skipped.
For more detailed operational and system information, refer to the hp Carrier Grade Blade Server bh3710
Service Manual.
Site Preparation
Prepare the site for installation as described in the hp Carrier Grade Blade Server bh3710 Site Preparation
Guide.
Unpacking the Blade Server
The following information is provided for blade server unpacking:
• Electrostatic Discharge (ESD) Precautions. When handling any electronic component or assembly (such
as the chassis, backplane, blades, and peripheral components) observe all antistatic precautions. An ESD
kit (HP PN A3025-80004 is available or supplied with this system. The kit contains one wrist strap, one
conductive sheet, and one antistatic foam pad.
• Always wear a grounded wrist strap when working on the equipment or printed circuit boards.
• Treat all assemblies, components, and interface assemblies as static sensitive.
• Avoid working in carpeted areas and keep body movement to a minimum while removing or installing
components to minimize buildup of static charge.
WARNING The blade server weighs approximately 29 kg (65 lbs) when fully loaded. At least two
people are required to lift the blade server into the cabinet and a third to secure it.
It is recommended that a mechanical assistance device be used to lift the blade
server into position. Failure to heed this warning may result in serious injury and
destruction of the blade server.

DC Power Supplies
Power supplies come in two parts and reside in the lower bay of the chassis. They are accessed from both the
front and rear of the chassis as illustrated in Figure 0-1.
Each power supply has two LEDs located on the front of the blade server that are used to determine the
operating condition. The top LED is green and illuminates whenever DC power is present and within
operating specifications. The bottom LED is red and illuminates whenever the power supply is in a fault
condition.

Grounding
The blade server must be grounded to earth via the ground lug provided on the chassis to ensure safe
operation, to prevent damage from electrostatic discharge, and to assure compliance with electromagnetic
compatibility requirements. The location is shown in Figure 0-1, Rear Power Supply view.
CAUTION The DB9 connector shown in Figure 0-2 marked “For Manufacturing Use Only”, was installed
for use during the manufacturing process. It cannot be used for anything else. If an RS232
-type plug is used in this receptacle, it could cause the power supply to reset, thereby losing
data being transmitted to the blades.
DO NOT USE THIS RECEPTACLE FOR ANY PURPOSE!

Blade Server Power Supply Connector
DC Power Input Module and Cable Connector Pinout Information
The power supply connector on the input module is a Positronics PLB06. The cable supplied for each power
supply is a 5-wire cable. All 4 wires on each cable must be connected. Two wires (red and black) are connected
to the –48VDC source and the remaining two wires (white and green) are connected to the DC return. All four
wires from the same power cord must be connected to the same power source. Each power supply filter
module may be connected to a different –48VDC source to provide power source redundancy.
