FAQ
How many devices can this switch power simultaneously with PoE?
The switch provides a total PoE budget of 250W, which can be distributed across its 16 PoE+ capable ports. The actual number of devices powered simultaneously depends on each device's power requirements. For example, it could power approximately 16 standard VoIP phones (7-15W each), 8 typical wireless access points (15-30W each), or a mix of various PoE devices totaling up to 250W. The switch automatically negotiates power delivery with each connected device according to IEEE 802.3af/at standards.
What types of SFP modules are compatible with this switch?
The switch features two dedicated SFP (Small Form-factor Pluggable) slots that accept standard SFP or mini-GBIC transceiver modules. Compatible modules include 1000BASE-SX for multimode fiber, 1000BASE-LX for single-mode fiber, 1000BASE-T for copper connections, and various other Gigabit Ethernet SFP transceivers. The slots are not shared with other ports, providing independent fiber connectivity options for uplinks or network expansion without consuming RJ-45 ports.
