This Hub's Serial # -> DS18L25561825. MIX & MATCH. Network Ports Eight [ 8 ] RJ-45 Ports. The hub was powered up. Picture 1 shows: Front of Hub & Power Adapter. Picture 2 shows: Back of Hub. Picture 3 shows: Top of Hub.
Hubs are reliable and fast. I've had port failures with switches but not with hubs. Unless someone is moving large files across the lan, there is no noticeable slow down using hubs.
