Selection notes

• Each capability is a reference for its cited manufacturer document for DS-3E1552P-SI, not a choice between conflicting editions. Confirm the actual hardware, firmware and supplied configuration.
• Per-port power ceilings and the shared PoE budget are separate limits; all ports cannot be assumed to deliver their individual maximum simultaneously. Whole-device consumption is a different rating.
• Optical modules, power units and mounting accessories are not assumed included. Confirm the exact module, fibre link, power supply and supplied kit.
• Manufacturer software features are not an activated ISD integration. Confirm the actual firmware, platform access and required configuration.
• Manufacturer references do not establish ISD stock, price, ETA, local warranty, authorisation, image rights or installation approval.
