TP-Link TL-SH1008 Power Consumption and Noise
The included power adapter is a 12V 1.5A unit that is a TP-Link branded unit. Again, we just want to draw your attention to the fact that these do not have FCC, UL, and other certifications that we would expect from devices like this.
Power consumption is shown in greater detail in the video, but the idle is around 4.4W without anything plugged in. Each additional 2.5GbE connection, on short 5m cables is around 1.2W incremental power consumption per port. The maximum we saw was around 16W, but we did not test eight ports at 100m so there is perhaps room to go up from there.
As for noise, there are no fans. So this unit is silent. We did not get coil or VRM whine, but as with any cheap component, things can vary here.
On those variances, let us next discuss auto-negotiation.
TP-Link TL-SH1008 Auto-negotiation Quirks
The 2.5GbE capable devices we used with the TL-SH1008 worked well at 2.5GbE speeds. We did, however, see challenges with the Intel X550 NIC onboard the ASUS Pro WS WRX80E-SAGE SE WiFi. The Intel X550 works at 1GbE, 2.5GbE, 5GbE, and 10GbE speeds and we have not seen many issues previously with this NIC.
When attached to the TL-SH1008, we saw something different. The NIC would go through 2.5Gbps and 1Gbps speeds but never properly negotiate. We could force the NIC to 2.5GbE speeds, but this was not ideal. It is 2022, and we expect devices to auto-negotiate properly. We also tried this with a PCIe-based X550-T2 and saw similar issues.
Again, with the i225 B3 stepping NICs and the Realtek 2.5GbE NICs, we did not see this issue, but it was noticeable on the 10Gbase-T parts.
The question is whether we would recommend this unit. On one hand, it is only $119, around $60 cheaper than the also unmanaged TRENDnet TEG-S380 8-port 2.5GbE switch we reviewed. That is 33% less expensive so it is hard not to say that, on a per-port basis, this is not cheaper.
We also just want to point out here that the switch itself did not work flawlessly with that auto-negotiation issue. We are accustomed to unmanaged 5-8 port switches just working without issue, so this is different. It also is lacking common certification markings that we would expect on any device we recommend. There is probably a reason that these cheap switches are not being sold on Amazon (and these are under $100 in China.)
The pinnacle of this class of product is something that checks all of the basic functionality boxes and that is inexpensive.
This is a case where the switch is just cheap. It mostly worked for us, but it is hard to give it a glowing recommendation because of some trade-offs made to keep costs down. Just because something is cheap, does not mean that it is necessarily good.
We are not going to end up recommending this switch. We have another cheap option that is a better value coming. We also will have the 10GbE SFP+ version review coming soon.
