Does the DGS-3620-52P support Power over Ethernet?
Yes, it supports PoE+ (802.3at) on all 48 copper ports with a total power budget of 740W, providing up to 30W per port.
Can I stack multiple DGS-3620-52P switches?
Yes, up to 9 units can be stacked using optional 10G stacking modules (e.g., DGS-3620SXM). Stacking allows unified management and high-bandwidth interconnection.
What type of SFP+ transceivers are supported?
The four SFP+ ports support 10GBASE-SR/LR/ER and 10GBASE-CU direct attach cables. For compatibility, use D-Link DEM series transceivers.
How do I reset the switch to factory defaults?
Press and hold the reset button on the front panel for about 10 seconds until all LEDs flash. Alternatively, use the CLI command reset config.
Does this switch support VLANs?
Yes, it supports 802.1Q VLAN with up to 4096 VLAN groups. You can configure port-based, tagged, and protocol-based VLANs via Web or CLI.
What is the typical power consumption?
Without PoE load, the switch consumes about 50-60W. With maximum PoE load (740W), total power consumption can reach 870W (system + PoE).
Is the switch fan noise noticeable?
The switch has two smart fans that adjust speed based on temperature. Under normal load, it is relatively quiet, but it can become audible under heavy PoE load or high ambient temperature.
How do I update the firmware?
Download the latest firmware from D-Link support. Then upload it via the web interface under System > Firmware Update, or using the CLI command copy tftp://[file] flash:image.
