Tenda TEM2008D: Specs, Features, Pros & Cons
Every one of the TEM2008D's eight ports runs at 2.5 Gbps. There is no slow port to plug the wrong device into, and no faster port to use as an uplink either, which shapes how the switch fits into a network more than any other line on its sheet.
It is Tenda's eight-port unmanaged 2.5G switch, the bigger sibling of the five-port TEM2005D: a steel case 177.5 mm wide and 26 mm tall, with no fan, made to sit on a desk or screw to a wall. Each port also negotiates down to gigabit and 100M, so older laptops, TVs and printers can share it with the faster machines. Tenda specifies Cat5e or better cable, the grade 2.5GBASE-T was designed to run over at full length, so existing Cat5e runs can carry the faster speed without being pulled again.
Tenda's own figures describe a non-blocking design. The 40 Gbps switching capacity is exactly eight ports at full duplex, forwarding is rated at 29.76 million packets per second, and the MAC table holds 16,000 entries. The rated maximum draw stays under 9.8 W, and each port has 4 kV surge protection.
The rest is what an unmanaged switch leaves out. There is no PoE, no VLAN, no link aggregation, no SFP+ cage and no way to watch traffic. Tenda also does not list jumbo-frame support for this model, which is worth knowing before setting a NAS to a 9,000-byte MTU.

How this VS Score was computed
Score 31: each known spec is measured against the median of all network switches (17 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 78% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
A 2.5G NAS on the TEM2008D shares its single link with every machine reading from it, because no port on the switch is faster. A 2.5 Gbps link carries about 312 MB/s before protocol overhead, so three PCs copying from the NAS at once share it at roughly 100 MB/s each, a little under what each would get from a gigabit link of its own. The upgrade shows when one machine copies at a time and fades when the whole office pulls from the server together.
Matched to the right desk, the ports are well used. A desk with a 2.5G NAS, two PCs, a games console and a router or access point with a 2.5G port uses the eight ports well, and every pair of devices gets a full 2.5G path between them. The five-port TEM2005D runs out of sockets on that same desk.
Where it stops making sense is a NAS with a 10G card. The TEM2008D will link it at 2.5G, and the extra speed the card was bought for stays unused. Ten-gigabit storage needs a switch with a 10G port to plug it into.
For a fanless, configuration-free box the TEM2008D does exactly what the label says. NETGEAR's MS110TX adds two SFP+ uplinks and VLANs to the same eight 2.5G ports, a difference that only counts once one machine on the desk outgrows 2.5G.

Networking assessment
What the specification table does not say on its own: what this device needs to connect, what speeds are realistic, what costs extra, and where it falls short. Every statement below is read from the verified sheet or written by an editor — nothing is estimated.
Test environment
Research-based assessment: this brief is derived from the manufacturer’s published specifications for the Tenda TEM2008D and the documents listed under Sources and verification. We have not run this unit on our own network, so nothing here is a measurement of ours.
Connection requirements
Unmanaged: it plugs into any router’s LAN port and needs no configuration, but it also offers none — no VLANs, no port monitoring.
PoE budget is 0 W shared across the powered ports — add up the draw of the cameras, phones and access points you intend to hang off it before assuming they all fit.
Throughput expectations
Switching capacity is 40 Gbps, enough for every port to run flat out at once — the usual case for a home or small-office switch.
Security support
Security-update cadence is not something manufacturers publish as a specification; see Support and updates below.
Known limitations
Not offered, according to the spec sheet: vLAN support, link aggregation, quality of Service (QoS), cloud management.
3 specifications are not published by the manufacturer and are shown as Unknown rather than guessed.
Support and updates
We have not found a published firmware support-lifetime commitment for this model. Update policies differ widely between brands; check the support page linked under Sources and verification before relying on it for a long deployment, and treat a device that has stopped receiving security updates as due for replacement.

The bottom line
The Tenda TEM2008D earns a VS Score of 31, below the median of the 17 network switches it is measured against (a score of 50 is level with that median).
- Who it’s for
- A desk or home lab where a 2.5G NAS, a couple of PCs and a 2.5G router or access point need to move files faster than gigabit, silently and with nothing to set up.
- Who should look elsewhere
- Anyone who needs PoE for an access point, VLANs for smart-home gear, or a 10G link to a faster NAS or switch, since no port goes beyond 2.5G.
- The trade-off that matters
- No settings at all is the appeal and the limit. The day a camera or a guest network needs its own VLAN, this switch has nothing to give and a managed one has to replace it.
- The main alternative
- NETGEAR MS110TX: eight 2.5G ports plus two 10G SFP+ uplinks, VLANs and a fanless case, for a network that needs a faster path out.
