Installing Your S100
Install the S100 in a physically secure location with strong physical access controls.
Symmetricom recommends that you read the operating environment requirements and other
specifications in “S100 Specifications” on page 119
, before starting.
Rack Mounting
The S100 is designed for mounting in a standard 19-inch (48.26 cm) rack. It is important to
keep the fan inlet and outlet areas clear to maintain air flow. If the unit is installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the rack environment may
become greater than that of the room. Be sure that the ambient temperature is no higher than
50°C/122°F. Make sure the unit is properly balanced and grounded.
Primary Power Connection
The S100 uses external AC power.
The unit has a power cable with a PH-386, IEC 320-C-13 three-conductor female connector
on the computer end of the cable. The other end of the cable has a NEMA 6-15P grounding
plug (US Standard, 15-amp, 125-volt, straight-blade plug).
