TRD-O-Meter gives an overview of the status of
the TRD infrastructure at P2
17
Operation of SM08
- still waiting for the report of the safety
commission on our infrastructure - TRD operating
during nights only - Rack internal power (e.g.
Ethernet switches) available 24h/7d - Cosmics
data taking to start in week 19

LV Power Supply Installation

• 50/90 power bins are
• installed at Point 2
• 16/90 Wiener power
• supplies are mounted
• 09/90 Wiener power
• supplies are operating
• sector 08 operating
• sector 09 installed
• GTU power operating
• PCU commissioned

20
LV Cabling and Sense Cabling

• a few bugs were found
• during LV cable testing
• - 1x flipped polarity
• - 2x loose screws in 6
• power bins we checked
• cabling of LV senses now
• performed by company
• no pretrigger LV cables
• installed yet

21
Inverted LV Channel Pin Out
LV power polarity occasionally flipped
photo shows correct connection after fixing the
bug
22
Trouble with Hot LV Cables
LV cable temperature was rising to 60 on one
cable during operation (default is 30) screw
connection inside Wiener power bin built at CERN
was faulty proper tightening of screws cures
the problem
23
HV System Patch Box

• 2 ISEG crates
• ready for operation
• using patch boxes
• as temporary HVDS
• replacement
• we will switch to
• ISEG-only solution
• as replacement for
• the HVDS
• this requires 40 new
• cables from CR4 to
• level 4 I/O 4 racks

24
DCS Network Monitoring Tools
D. Emschermann
developed monitoring tools for status control of

• Netgear switches

DCS Network
TRD DCS network almost commissioned still
fighting bugs together with IT in the access to
our Netgear switches. operation of
devices within DCS network works smoothly
