Racks Power Cables Interlocks Network


Racks [cooling & mechanics]

All racks in UX and CR4 are prepared• Turbine, heat exchanger, air deflector are mounted

• Few turbines still missing

• Adapted to future content of each rack• Any object that would significantly obstruct the vertical airflow is

placed above turbine or below deflector (and will not be cooled!)• If you have more of these that we did not know of:

either make them transparent to airflow, or rack has to be modified (need to empty the rack)

• Water cooling is operational for all racks• Hydraulic connection of devices done by installation team

(Philippe Bouvier)• Give some advance warning, please


Racks [cooling & mechanics]

• Installation accessories are available at Point 2• Slides, nuts and bolts etc.• Installation is detector responsibility; we provide ‘best effort’

assistance

• Contact us for any ‘non standard’ mounting• Non standard, special equipment (e.g. “TOF crate” for T0)• Special mounting of standard equipment (e.g. SSD Easy crates)


Racks [monitoring]

All racks are equipped with monitoring system• ELMB based, located in turbine chassis

Monitors status of the rack• Turbines running, temperature, rear door, thermoswitch

Interface provided centrally CR4 being commissioned

• UX (c-area) 1-2 weeks; waiting for cable• Rest of UX 3-4 weeks (cables permitting)


Racks [protection]

All racks are equipped with a protection system Temperature:

• A thermoswitch (turbine chassis) will switch off the power to the rack in case of overheating

Smoke:• A smoke detector (turbine chassis) will switch off the

power to the rack upon detection of smoke

Fire fighting (UX C-area only):• A CO2 fire extinguishing system will release CO2 in the

rack in case of fire


Power

Power connections of your equipment in the racks:• All ‘big consumers’ will be connected directly to power

distribution unit at top of rack (“Polish boxes”)• Wiener LV and VME, CAEN 48V supplies (tri)• Protected by 16A circuit breaker (3 per rack)• If you provide us with the power cords we will connect them


Power

• All other equipment will be connected through power strip(s) mounted in the racks

• With IEC320 sockets• Limited to 10A per socket• Power cords (1 to 5m) available

from CERN stores (04.66.31.A)• Not allowed to connect ‘portable equipment’ (laptop, scope,

soldering iron etc.); thus no need to make ‘adapters’• Use ‘wall outlets’ for this (swiss type)

• These are protected (30mA differential)


Power control

Each rack is powered from a single power unit• So called “Hazemeyer”• Two racks on a power unit in CR4• Limited to 32A• Remote control and monitoring

(provided centrally)


Power

Note that all power in the racks is switched off• Each power unit is “consigné”• For safety reasons

Before first power on a procedure has to be followed• Documentation of the installation• Inspection of the installation• Contact Marc Tavlet for details


Cables

Some control cables are taken care of by us:• Wiener VME crate control (CANbus)

• Being installed

• Iseg HV crates (CANbus)• Installed

• Control cable for Easy system (from branch controller (A1676) in mainframe to Easy crate; CAEN specific bus)

• Being installed; HMPID already done• Connection between crates is detector responsibility

• Flat cable if within rack; 25-pair shielded cable if outside rack

• We can help you, but you’ll have to ask…

Cabling for CAEN Easy 48V service

power To power

control part of the Easy crates/modules

Propose to add small power supply in same rack as branch controller

We will take care of PS and cabling

© CAEN

Taken care of by DCS

In UX racks

In CR racks


Cabling for ELMBs

ELMB needs CANbus and power• Brought to the first ELMB in your chain in a single cable• Central power supply units in CR3 (close to your PCs)• Some are being installed (e.g. DCS, TPC), others wait

definition of final position of first ELMB (‘ node’ in cable database speak)

• We will contact you to check, detector by detector• Cable is available at point 2• We will take care of installation

• From this point onwards installation is detector responsibility


ELMB system We provide the ‘patchbox’

from big to small cable

Recommended cable for ELMB daisy-chain is CANbus cable 04.21.60.430.5(contact me for wiring details)

120Ω termination, on last ELMB

Alu or Inox DINrail, for ELMB mounting(steel: 06.01.85.260.8)

Connection blocks for sensor cabling


Cabling for interlocks

We will take care of: Interlock cables from gas system to HV system

• Being installed

Interlock cables from cooling plant to LV system• Cannot be installed yet (missing cable trays on A side)• Need more input from some detectors

• You will be contacted

Interlock cables to cooling plant• From DSS, to stop cooling plant on detection of leak


Cabling for interlocks

Detector responsibility: Distribution of interlock signal to equipment in the

same location Cabling of the detector inputs to DSS

• From sensor to DSS system• E.g. pressure sensors for TPC, TRD; temperature sensors

for SPD, SSD, Muon

The DSS system will be extended (in UX) for the use by detector interlocks


Network Whole network is installed and operational, since January

2007• DCS network in racks (UX, CR and SG)• DCS network in ALICE control room (ACR)• GPN network outlets on the walls, or outside

racks (UX, CR, SX and SG)• Wireless GPN network (UX, CR and SX)• DAQ and HLT networks (CR1 and CR2)

This should be sufficient for the commissioning and first months of operation• Any extension requests will be collected, and installed during next

shutdown


Network – Netgear Netgear switches (for DCS boards/RCU)

• Installed for TRD and TPC (~35 units)• Others ‘on request’

• In order not be in the way for cabling work

• Give us a few days advance warning

Connectivity:• Individual connection per switch for TRD• Others 1 connection per group of switches

• TPC requested 2nd connection for redundancy

Who is doing what:• Connection up to Netgear is done by DCS• Connection from Netgear to detector is detector responsibility

Connection of devices

As discussed in commissioning meetings• Provide all information of the device to be connected to

Peter Rosinsky, well in advance• Peter will inform you about allocated IP number• The cable between outlet and device will be provided

On the ‘other end’:• All detector PCs are installed and operational• See Peter’s talk on installation procedure

Contact us in case of doubt


Summary Give us some advance warning before you start installing

your equipment• To allow preparation of cooling, power, network etc.

Special procedure to be followed before you are allowed to power a rack

Most control and interlock cables are being installed• In case of doubt, contact us• DSS extension for interlocks being ordered

48V service power for CAEN Easy systems will be installed ELMBs and accessories are available; contact me Network is operational

• Connection requests via Peter Rosinsky

Let us know what you are planning to do at Point 2We are available to help you
