If the AP is currently in Lightweight Mode (CAPWAP), it must be converted. Connect to the AP via console. Reload the AP and enter the boot menu. Ensure the AP has a working IP address. 3. Loading the TAR File via CLI
The running Mobility Express (ME) 8.3.150.0 is an enterprise-grade 802.11ac Wave 2 access point. While highly capable, users frequently report "hot" operational temperatures, which is largely due to its high-performance internal hardware and fanless design. Performance & Thermal Review
: This proactive spectrum intelligence identifies and mitigates wireless interference across 20-, 40-, 80-, and 160-MHz wide channels. Technical Specifications & Pricing Use the following commands in the AP CLI
If the AP is underpowered (running on standard 802.3af), it may struggle with efficiency, leading to higher internal temperatures as it tries to throttle or manage power-intensive tasks. Ensure you are using a PoE+ capable switch like the Cisco Catalyst 3750X/3850 or a dedicated PoE+ injector. 2.
