Can this switch be powered by a standard PoE switch (like a 48V 802.3af/at switch)?

No, this switch accepts PoE input at 12-24V (non-standard) on the RJ45 ports. Standard 802.3af/at switches output 44-57V. You need a PoE injector or switch that supplies 12-24V, or use the DC jack (output only) is not for input. If you have a standard PoE source, you'll need a voltage converter or a different model.

What is the maximum distance for the fiber ports?

It depends on the fiber type and transceiver. Multi-mode fiber reaches up to 550m (850nm) or 2km (1310nm). Single-mode fiber can go 2, 20, 40, 60, 80, or 100km depending on the module chosen. The switch comes with fixed SC connectors, but you can request SFP slots or other connector types if ordering custom.

Do I need to configure anything before using the switch?

No. It's unmanaged and plug-and-play. Just connect power via PoE on one of the RJ45 ports, attach your fiber cables, and devices will start communicating immediately. No IP setup, VLAN config, or software required.

Can I use SFP modules instead of the built-in SC connectors?

The default version of this switch comes with fixed SC fiber ports. However, the product parameters note that SFP, FC, or other connector types are optional when ordering. If you need SFP slots, please specify when purchasing. The standard SG208RP has SC connectors.

What kind of Ethernet cable do I need for the RJ45 ports?

Use Cat5e or better cable. The ports support 10/100/1000Mbps and the maximum distance is 100 meters. Since the switch also receives PoE power through these ports, ensure the cable can handle 12-24V power delivery (standard Ethernet cable is fine).

Can this switch be mounted on a wall?

Yes. The metal housing has mounting ears (or you can use optional brackets). It supports desktop, wall-mount, and 19-inch rack-mount installations. The compact size (215x94x27mm) fits easily in a small cabinet or on a wall near the fiber termination point.

What is the power consumption of this switch?

The switch itself consumes less than 3 watts. That's extremely low — it barely generates heat, so no fan is needed. The DC output jack can provide up to 12V/1A (12W) to power a small external device like a camera or access point, but that power is drawn from the PoE input, so plan your total power budget accordingly.

Does it support jumbo frames?

Yes, the switch supports jumbo frames up to 9K bytes. This is helpful for IP surveillance or large file transfers where bigger packets reduce overhead and improve throughput. Just make sure your connected devices also support jumbo frames and are configured to the same MTU size.

Can I use both RJ45 ports simultaneously?

Yes. Both RJ45 ports can be used for data traffic, and both accept PoE input. You can connect one to a PoE source for power and the other to a workstation or another switch. The switch will forward traffic between all ports (2 RJ45 + 8 fiber) at wire speed.

Is this switch compatible with single-mode and multi-mode fiber?

The SC ports support both single-mode and multi-mode fiber, depending on the transceiver module used. The product parameters list multi-mode distances (550m/2km) and single-mode distances (2 to 100km). When ordering, you can specify the fiber type and distance you need. The switch itself is wavelength-agnostic, so it works with 850nm, 1310nm, 1550nm, etc.
