Mounting APRESA into a 19 inch cabinet
The APRESA server is designed to fit in standardized 19-inch server cabinets and will take 1U or 4U in
height. Depending on the telecommunication system to be tapped up to 4 patch panels (each 1U in
height) may be involved in the total installation and need to be considered when planning cabinet space.
The required cabinet depth is 45cm for the APRESA unit. For proper cable routing of you must reserve
an extra 10cm wire routing space minimal.
The power consumption of the unit is low enough not to affect the thermal balance of the neighbor-
equipment placed above and below. You must always check not to block the airflow on adjacent
equipment. To be safe, just have 1U space unused on both sides of the APRESA.
For easy access after installation we advise to use the optional available sliders (ART 090.04090).
Use 4 sets of standard screws & cage nuts to fixate the APRESA in the 19"-RACK (not supplied).

Apply power to the APRESA.
THIS EQUIPMENT MUST BE EARTHED
FOR SAFETY REASONS
The APRESA can be powered from any (EARTHED !! ) 90-260Vac mains outlet.
The power consumption of the APRESA is labeled on the housing and is in the range of 80-120W,
depending on interface cards- and storage (hard drive) options.
If the tapped communication system is powered by a UPS you may consider to feed the APRESA also
from the UPS enabling sustained recordings to continue during power interruptions. Note that tapped
telecommunication lines will not be influenced by a power down of the APRESA.
Critical applications may use a redundant power supply. This option is easily identified by 2 IEC mains
power inlets at the back of the APRESA. Both inlets must be individually connected to mains, preferably
on different main groups in the electrical installation or different UPS-s. Refer to chapter 10 for more
information on redundant power supplies.
The APRESA chassis should (and must) be grounded for safety reasons, according to standard industry
requirements. A simple way to comply is using the third pin on the APRESA-PSU power inlet. Using a
good quality standard (earthed) mains cable and insert it to an EARTHED mains source. Absent or
improper grounding may cause instability in operation as well as unsafe situations.
