14-Slot AdvancedTCA ShelfShelf Installation11596-100/-101/-102/-1033 Shelf InstallationInstall the system in a restricted access area, where access can be gained onlyby service personnel through the use of a special tool, lock and key, or othermeans of security.Choose a site with a dry, clean, well-ventilated and air-conditioned area thatmaintains an ambient temperature of 5 C to 45 C (41 F to 113 F).3.0.1 Ensuring Overcurrent ProtectionThe system relies on the protective devices in the building installation forprotection against short-circuit, overcurrent, and earth (grounding) fault. Ensurethat the protective devices in the building installation are properly rated toprotect the system, and that they comply with national and local codes.3.0.2 Ensuring Proper Airflow Install the system in an open rack whenever possible. If installation in anenclosed rack is unavoidable, ensure that the rack has adequate ventilation. Maintain ambient airflow to ensure normal operation. If the airflow is blockedor restricted, or if the intake air is too warm, an over temperature conditioncan occur. Ensure that cables from other equipment do not obstruct the airflow throughthe Shelf. Use filler panels to cover all empty chassis slots. The filler panel preventsfan air from escaping out of the front of an open slot.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.3.0.3 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 powerextension cables, and missing safety grounds. Keep the area around the chassis free from dust and foreign conductivematerial.www.a-tca.com / www.schroff.biz10R1.1, July 23, 2008
14-Slot AdvancedTCA ShelfShelf Installation11596-100/-101/-102/-1033.1 UnpackingCaution!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 theShelf 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.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 theShelf must be returned. If the packaging is damaged and possible Shelf damage is present, report tothe shipper and analyze the damage.www.a-tca.com / www.schroff.biz11R1.1, July 23, 2008
14-Slot AdvancedTCA ShelfShelf Installation11596-100/-101/-102/-1033.2 Rack-MountingWarning!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 touse a mechanical lift or remove all hot-swappable equipment for weightreduction.Warning!Do NOT stack the Shelf on top of any other equipment. If the Shelf falls, it cancause severe bodily injury and damage the equipment.Caution!Do NOT remove the Transportation Locks (See Fig. 1) before the Shelf iscompletely 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 mustwear an ESD wrist strap to prevent static damage.This ATCA 14-slot Shelf can be installed in 19“ equipment racks. The rack mustbe accessible from the front and rear for equipment installation.Mounting brackets and cable trays come with the system. Allow sufficientclearance around the rack for system maintenance.www.a-tca.com / www.schroff.biz12R1.1, July 23, 2008
14-Slot AdvancedTCA ShelfShelf Installation11596-100/-101/-102/-103Mounting Instructions: Ensure that the rack is constructed to support the weight and dimensions ofthe Shelf. Install any stabilizers that came with your equipment rack before mountingor servicing the system in the rack. Load the rack from the bottom to the top, with the heaviest system at thebottom, avoid uneven mechanical loading of the rack.Caution!Never fix the Shelf only with the mounting brackets! Due to the weight of theShelf you must use two chassis-support brackets or a rack mount tray.Figure 6: Chassis-Support Brackets127068583Chassis-Support Brackets.www.a-tca.com / www.schroff.biz13R1.1, July 23, 2008

The relays are capable of carrying 72 VDC or 1 A with amax. rating of 30 VA.4.2.2 Telco Alarm LEDsThe Shelf Alarm Panel provides the Telco Alarm LEDs. These LEDs indicatepresence of Critical, Major and Minor alarms as follows:Table 4: Telco Alarm LEDsStateDescriptionOffNo alarm activeOnAlarm activeFlashingAlarm active, but silenced4.2.3 Alarm Silence Push ButtonThe Alarm Silence push button on the Shelf Alarm Panel faceplate deactivatesthe alarm relays. During the time Alarm Silence is activated, the Alarm LEDsflash. By pressing the Alarm Silence push button a second time, the alarm relaysare reactivated and the Alarm LEDs are solid.The Alarm Silence push button only activates the Alarm Silence state, butdoes not reset the alarms. If the silence interval (default 600 s) is exceededwithout resolving the alarms, the alarms will be re-initiated.4.2.4 Alarm ResetHardware Reset:Two relay inputs at the DB15 connector are used to reset the Minor and Majoralarm state.The reset inputs accept timed pulse inputs for clearing Minor and Major alarmstates. Reset is accomplished by asserting a voltage differential from 3.3 VDCto 72 VDC for between 200 ms and 300 ms. The acceptance voltage range isfrom 0 to 48 VDC continuous (handles up to 60 VDC at a 50% duty cycle). Thecurrent drawn by a reset input does not exceed 12 mA.There is no hardware reset (reset input) for the Critical Alarm state.Software Reset:The RMCP and CLI functions can be used to set and reset the Telco Alarms(incl. Critical Alarm). See the Pigeon Point Shelf Manager External InterfaceReference for more information.www.a-tca.com / www.schroff.biz23R1.1, July 23, 2008

When the system is powered on, do NOT touch the powerterminals!Warning!This Shelf is intended to be grounded. Ensure that the Shelf Ground terminalsare connected to Protective Earth (PE) of the building.Warning!Although there are fuses in the power entry circuit of the Shelf, the power lineshave to be protected on rack level with 30 A breakers.Warning!Remove jewelry (rings, watches.) before working on equipment that isconnected to power lines!Warning!Before removing a PEM, make sure that the Power Segments of the otherPEM are fully functional.Danger of electrostatic discharge!Static electricity can harm delicate components inside the Shelf. You mustwear an ESD wrist strap before exchanging any part or electric component!Caution!To maintain proper airflow, do not leave a PEM slot open.Under normal operation, the green OK LED on the PEM is lit, indicating thatthere is supply voltage on all power feeds and the PEM is fully functional.When the red Failure LED lights up, there is either a supply voltage missing, afuse blown or the PEM not working. Before replacing a PEM, check if all powerfeeds are present at the PEM connector.www.a-tca.com / www.schroff.biz25R1.1, July 23, 2008
