LSS2200-8P Install Guide

Most power supplies have a de-rating curve for ambient temperatures above 50°C. Be sure to consider the
power supply de-rating if used in environments over 50°C.
The overall thermal dissipation of all devices in the installation must also be accounted for. The LSS2200-8P is
characterized in a still air (0 LFM) ambient environment of -40 to +65°C. Other heat sources may be specific to
the actual application or installation and will contribute to the overall ambient temperature, which may require
further de-rating for all devices. This is especially critical in a sealed enclosure, cabinet or confined space.
As these factors are application-specific, additional attention should be given during evaluation and testing.
Setting the Power Supply Values in Switch Software
CAUTION
: Always match the PSx input supply to the Power Supply 1 and Power Supply 2 software
setting. Mismatching will cause the LSS2200-8P to think it can draw more power from the external supply than it
is capable of providing and results could be detrimental.
Note
:
The power supply wattage value(s) must be manually set in the software by the user to match the
connected external power supply(ies). The LLSS2200-8P uses this wattage as the “PSE Power Available” to
determine if enough power is available during PoE PD classification to power up connected PDs.
