+5V (+/- 5%) @ 1.65A (typ): Provides power to internal circuitry
+12V (+/- 5%) @ 2.0A (max): Provides power to externally connected
PCIe drives (via front-panel PCIe connector)
+5VDC (+/- 5%) @ 3.9A (max): Provides power to externally
connected drives (via front-panel Drive Power connector)
+12VDC (+/- 5%) @ 3.1A (max): Provides power to externally
connected drives (via front-panel Drive Power connector) and to the
internal cooling fan (fan current: 0.15A typ)
3.3 Thermal considerations
The maximum ambient operating temperature of the Universal Bridge is 55 degrees
Celsius. Note that this is the ambient temperature around the bridge inside the forensic
workstation, not the ambient temperature of the room in which the workstation is located.
For reference, normal room ambient temperature is approximately 22 C. With an
expected temperature rise inside a typical, active forensic system of 10 – 15 degrees C,
that puts the typical bridge ambient operating temperature in the range of 32 – 37
degrees C, which is well below the maximum of 55 C.
The environmental requirements for the Universal Bridge are shown in the table below.
Operating ambient temperature range
0 to 55 degrees C (no airflow; at bridge inside
forensic workstation)
Storage ambient temperature range
Up to 90% (non-condensing)
Note that systems designed for the original T356789iu design should work without issue
when used with the new T356789iu-R2 variant. (See the Introduction section at the
beginning of this guide for details on the R2 variant.) The main consideration is to ensure
that cables and/or other internal system components do not interfere with the air pocket
directly above and around the higher power components on the bridge. Those
components are the processor/heatsink/fan setup and the SAS host controller.
