IMPORTANT NOTES:
“48SH” indicates the 48‑port SFP/SFP+ version; confirm that your optics and transceivers support 10 GbE and breakout configurations as needed.
Uplink QSFP+ ports can be configured either for native 40 GbE or broken out into up to 4×10 GbE each—check cabling and optics accordingly.
Since this model is for data‑center level access/leaf deployments, ensure your rack, power, and cooling infrastructure are sized appropriately.
Verify whether AC power variant matches your rack’s feed and that airflow orientation (front‑to‑back) is compatible with your hot/cold aisle design.
Confirm firmware version, licensing requirements for advanced features, and spare‑part availability in your region before procurement.
