How to evaluate this exact configuration
Access connections
Access connections for DCS-7280SR3-40YC6-F: 36 x 1/10/25G SFP; 4 x 10/25G SFP. List the endpoints, required link speeds and spare connections before choosing the switch count. Do not count an uplink socket as another equivalent copper endpoint port.
Uplink arrangement
Uplink arrangement for DCS-7280SR3-40YC6-F: 6 x 100G QSFP100. Match the upstream port format, cable or transceiver, link speed and intended redundancy. Retain every qualification in the stated uplink arrangement when preparing the bill of materials.
Powered endpoints
DCS-7280SR3-40YC6-F is recorded as non-PoE. If access points, phones or cameras need power from the switch, choose a documented PoE variant or plan another power method; the access-port count alone does not establish that capability.
Power supply configuration
Power supply configuration for DCS-7280SR3-40YC6-F: 2 x AC supplies included; front to rear airflow. Write the required supply quantity, input power and airflow into the quote. A supply slot and an included supply are different bill-of-materials items.
