Shelf Installation 4 R1.0, July 2018
2 Shelf Installation
Choose a site with a dry, clean, well-ventilated and air-conditioned area that
maintains an ambient temperature of 5°C to 45°C (41°F to 113°F).
2.1 Ensuring Overcurrent Protection
The system relies on the protective devices in the building installation for
protection against short-circuit, overcurrent, and earth (grounding) fault. Ensure
that the protective devices in the building installation are properly rated to
protect the system, and that they comply with national and local codes.
2.2 Ensuring Proper Airflow
• Install the system in an open rack whenever possible. If installation in an
enclosed rack is unavoidable, ensure that the rack has adequate ventilation.
• Maintain ambient airflow to ensure normal operation. If the airflow is blocked
or restricted, or if the intake air is too warm, an over temperature condition
can occur.
• Ensure that cables from other equipment do not obstruct the airflow through
the Shelf.
• Use filler panels to cover all empty chassis slots. The filler panel prevents
fan air from escaping out of the front of an open slot.
2.3 Creating a Safe Environment
• Keep tools and chassis components off the floor and away from foot traffic.
• Clear the area of possible hazards, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
• Keep the area around the chassis free from dust and foreign conductive
material.
Caution!
To maintain proper airflow, all open slots must be covered with filler panels.
The filler panel should include an airflow baffle that extends to backplane.

2.4 Unpacking
Consider the following when unpacking and storing the Shelf:
• Leave the Shelf packed until it is needed for immediate installation.
• After unpacking the Shelf, save and store the packaging material in case the
Shelf must be returned.
• If the packaging is damaged and possible Shelf damage is present, report to
the shipper and analyze the damage.
Caution!
When opening the shipping carton, use caution to avoid damaging the Shelf.
Danger of electrostatic discharge!
The Shelf contains static sensitive devices. While unpacking and handling the
Shelf you must wear an ESD wrist strap to prevent static damage.
Caution!
Do NOT use the Fan Tray and PEM handles or cable trays as lifting points.

2.5 Rack-Mounting
This ATCA 14-slot Shelf can be installed in 19“ equipment racks. The rack must
be accessible from the front and rear for equipment installation.
Mounting brackets and cable trays come with the system. Allow sufficient
clearance around the rack for system maintenance.
Warning!
Do NOT move the Shelf by yourself. Due to the height and weight of the Shelf,
at least two persons are needed to accomplish this task. We recommend to
use a mechanical lift or remove all hot-swappable equipment for weight

reduction.
Warning!
Do NOT stack the Shelf on top of any other equipment. If the Shelf falls, it can
cause severe bodily injury and damage the equipment.
Caution!
Do NOT remove the Transportation Locks before the Shelf is completely fixed
in the rack.
Caution!
Do NOT use the Fan Tray and PEM handles or cable trays as lifting points.
Danger of electrostatic discharge!
The Shelf contains static sensitive devices. While handling the Shelf you must
wear an ESD wrist strap to prevent static damage.

Shelf Power Connection 7 R1.0, July 2018
3 Shelf Power Connection
Hazardous voltage!
Before working ensure that the power is removed from the power connection 
cables. When the system is powered on, do NOT touch the power terminals!
Warning!
Avoid electric overload. To avoid electrical hazard, do not make connections
to terminals outside the specified voltage range for that Shelf.
Warning!
Ensurethar the Shelf is grounded.Ensure that the ShelfGroundTerminals are
connected to Protective Earth (PE) of the building.
Warning!
Although there are fuses in thepower entry circuit of the Shelf, the power lines
have to be protected on rack level with breakers.
Warning!
Remove jewelry (rings, watches...) before working on equipment that is 
connected to power lines!
Danger of electrostatic discharge!
Static electricity can harm delicate components inside the Shelf. You have to
wear ESD wrist straps before exchanging any part or electric component!
The Shelf can be powered using regular telecommunication power sup-
plies of -48/-60 VDC with a VDC return.
The specified voltage range is from -40.5 VDC to -72 VDC.
The Shelf supports redundant power supplies but the two supplies
should be independently powered.

3.3 Power Entry Module
3.4 Introduction
Two pluggable redundant Power Entry Modules (PEMs) are located at the rear
bottom side of the Shelf
Each PEM provides power terminals for a 210 A power feed. Each power feed
consists of up to four –48 VDC cables and the corresponding return cables.

Each input feed is divided internally at the PEM in 6 output branches toward the
backplane. In this way, each PEM has 1 input feed and 6 output branches.
Over current protection is provided by 50 A fuses in each output branch.
The power filtering consists of filtered power terminals and a discrete line-filter
for each power branch.
The input voltage range for the Shelf is from -40.5 VDC to -72 VDC.
Hazardous voltage!
Before working ensure that the power is removed from the power connection 
cables. When the system is powered on, do NOT touch the power terminals.
The Shelf can be powered using a regular telecommunication power supply of
-48/-60 VDC with a VDC return. The specified voltage range is from -40 VDC
to -72 VDC.The Shelf supports redundant power supplies but the two supplies
should be independently powered.

4.1 Ethernet Interfaces
The front panel ETH0 Ethernet connector is intended for service use only or for
debugging purposes in laboratory environment. The computer which is
connected to this interface must be located nearby the shelf manager with an
Ethernet cable that is not longer than 10 m.
The front panel Ethernet connector MUST NOT be connected to a
Telecommunication Network Circuit that leaves the building.
TheETH0 interfaceofthe shelf managercanmanually beswitchedbetween the
front panel RJ45 connector (“Front”-position of the rocker-switches) and the
backplane connector going to the hub board base interface (“Back”-position of
the rocker-switches).
The ATCA specification requires a base channel interface between the shelf
manager and the Hub board.
The ETH0 rocker-switches MUST be in “Back”-position in normal operation of
the shelf manager in an ATCA-shelf.
Figure 8: ETH Switches shown in default position
4.2 Shelf Manager RS-232 Console Serial Interface
TheShelfManager provides an RS-232 consoleinterfacethatprovidesa full set
of RS-232 signals, including modem control. These signals are routed through
the Shelf Manager backplane connector to a RJ45 connector on the front panel
of the lower Fan Tray.
12708853
The serial console default configuration is:
• 115200 baud
• no parity
• 8 data bits
•1stopbit

Shelf Manager 16 R1.0, July 2018
4.3 Command Line Interface (CLI)
The Command Line Interface (CLI) connects to and communicates with the
IPM-devices of the Shelf, the boards, and the Shelf Manager.
The CLI is an IPMI-based library of commands, service personnel or system
administrators can access the CLI through Telnet, SSH, or the Shelf Managers
serial port on the SAP.
With the CLI, users can access information about the current system status
including sensor values, threshold settings etc.
Users can also access and modify Shelf- and Shelf Manager configurations,
perform actions on a FRU a.e. set fan speeds etc.
4.3.1 Basic CLI Commands
Service personnel can read system information, FRU information and sensor
dataswiththefollowingbasiccommands. ForafulllistofallCLIcommandsrefer
to the Pigeon Point Shelf Manager External Interface Reference Manual.
