3.2.4 Grounding Requirements
A good grounding system is not only the basis essential to the stable and reliable switch
operation, but also an important guarantee of lightning protection, anti-interference and
ESD-prevention. The user must provide good grounding system for the switch.
3.2.5 Power Supply Requirements
The S9500 series adopt redundant PSUs. Where,
z
AC PSU:
Rated voltage: 100 VAC to 240 VAC, 50 Hz or 60 Hz
Maximum tolerance: 90 VAC to 264 VAC, 50 Hz or 60 Hz
Maximum power output: 600 W (S8502)/1200 W (S9505)/2000 W (S9508/S9512)
z
DC PSU:
Rated voltage: –60 VDC to –48 VDC
Maximum tolerance: –72 VDC to –36 VDC
Maximum power output: 600 W (S8502)/1200 W (S9505)/2000 W (S9508/S9512)
3.2.6 Space Requirements
For the sake of adequate ventilation and easy equipment maintenance, you are
recommended to keep one meter of clearance between the rear/front of the switch
cabinet and the wall surface or other devices. If the optional cabinet is desired, the clear
height of the equipment room must be more than 3 meters inclusive.
3.2.7 Cabinet-Mounting Requirements
Before cabinet-mounting the switch, make sure that the cabinet meets the following
requirements:
z
Better mount the switch in an open cabinet. However, if you want to mount it in a
closed cabinet, make sure of the availability of a good ventilation system.
z
Make sure that the cabinet stands steadily enough to support the weight of the
switch and the accessories.
z
Make sure that the switch fits the cabinet size. Leave some clearance beside the
left and right panels of the switch for chassis ventilation.
