1. Temperature rating
This is the specification that most often forces the decision. Interior temperatures inside a sealed outdoor enclosure sit well above ambient, so the switch must be rated for the cabinet, not the weather report.
The Lysora LS2T-8GT2SFP-HP is rated -40 °C to +65 °C, extending to +80 °C in ventilated cabinets — an envelope no commercial switch is designed to meet.
