Important Deployment Considerations
Consider the following items before deploying ISW-Series switches.
Generation deployment considerations
•
Industrial grade SFPs, with maximum temperatures of up to 85°C, are required for
extended temperature operations.
•
ISW-Series switches are fan-less. In order to achieve the rated operating
temperature, the switches require an airflow of 40 to 100-LFM.
ISW-4W-4WS-4X deployment considerations
•
SFPs are the primary component at risk for exceeding their thermal limits. SFPs will
maintain operation in a safe environment through the reduction of PoE power in the
system.
•
When the system enters operational restriction mode due to thermal limits, the PoE
power is reduced from 360W total to 180W total. The highest numbered ports drop
PoE in decreasing order until the PoE power is at or under 180W.
•
In the event the reduction to 180W of PoE power is insufficient, ALL PoE power
delivery is turned off.
•
If the system continues to overheat, the SFP TX/RX is turned off until the system
cools down below 65°C (ambient).
ISW-24W-4X deployment considerations
•
System operational specifications as provided are for when the unit is racked and
maintains 2-RU of separation above and below the unit, using 5-RU of total rack
space.
•
When the unit is racked and maintains only 1-RU of separation above and below the
unit, using 3-RU of total rack space, the thermal operational range is reduced.
•
When the unit is racked and does not provide any separation from adjacent
racked equipment, using 1-RU of total rack space, the thermal operational range is
extremely limited.
•
The system can support 720W of total PoE power. However, that is limited to
distribution at a maximum of 240W for each set of 8 ports (1-8, 9-16, 17-24).
•
SFPs are the primary component at risk for exceeding their thermal limits. SFPs will
maintain operation in a safe environment through the reduction of PoE power in the
system.
