β FAQ - Frequently Asked Questions
Q : Does this switch support virtual stacking?
R : Yes, the DES-3200-28P supports virtual stacking of up to 32 units with single IP management (SIM), allowing centralized administration of your network infrastructure.
Q : What is the difference between PoE and PoE+ ports?
R : Ports 1-4 support PoE+ (up to 30W) to power demanding devices like PTZ IP cameras or high-performance Wi-Fi access points. Ports 5-24 support standard PoE (15.4W) for IP phones, fixed cameras, and small network devices.
Q : Is the switch compatible with metropolitan networks?
R : Absolutely, the DES-3200-28P is specifically designed for Metro Ethernet, FTTX, and ETTX applications with MEF certification. It supports Ethernet ring topologies and offers connectivity up to 20 km with appropriate SFP modules.
Q : What redundancy protocols are supported?
R : The switch supports multiple protocols including STP (802.1D), RSTP (802.1w), MSTP (802.1s), ERPS, and link aggregation 802.1AX/802.3ad to ensure high availability.
Q : Does the switch support IPv6?
R : Yes, the DES-3200-28P is IPv6 Ready and supports ICMPv6, ensuring compatibility with modern network infrastructures and future migrations to IPv6.
Q : What is the power consumption of the switch?
R : The maximum consumption is 250.78 Watts under full PoE load, and only 24.4 Watts in standby mode. D-Link Green features further optimize consumption based on actual usage.
