1. Product overview
The FR-2RU-10-2, hereafter called "sub-rack", is a compact sub-rack frame, providing
space for up to 10 Flashlink modules of any combination, in addition to two fixed
positions for power supply modules.
The sub-rack features maximum flexibility as every module comes with a suitable back-
plane module, which takes up n x 7TE spacing. This means that any combination of all
modules can be fitted into the sub-rack, or expanded / rebuilt in the future, when other
functionality is needed. Each sub-rack has an address setting available through DIP-
switches on the rear, for use in combination with the GYDA-SC System Controller card.
The Flashlink system is built on a low-power consumption philosophy where no fans
are needed. This saves the user from fan replacements, fan cleaning and fan filter kits.
Power consumption
The current draw in the Flashlink frame is limited by the power supplies.
Overloading the power supplies will cause the power units to malfunction.
Please read chapter 2.4 for further details!
Heat dissipation
The heat dissipation is based on convection, and it is therefore very
important not to block the warm air exhaust on the top.
Our guideline is that for every 200W of dissipated power, 1RU of open rack
space is needed above the uppermost frame for hot air exhaust.
