Product Features

1. DHR-800P/DHR-800 is a 8-port modularized 19" Rack mount
10/100Mbps Dual Speed Ethernet Stackable Hub, complies with the
IEEE802.3 10Base-T and IEEE802.3u 100Base-TX Class II
standard.
2. DHR-800P and DHR-800 are the same product series and can stack
with each other.
• DHR-800P is the 8-port Dual-Speed Ethernet Hub with internal
switching module – called "Primary Hub"
• DHR-800 is the 8-port Dual-Speed Ethernet Hub without

10Base-T segment and 100Base-TX segment.
5. DHR-800 provide two speed auto-negotiation, but 10Base-T and
100Base-TX segments can not communicate with each other, except
by stacking with DHR-800P primary model.
6. At the front panel, one additional RJ-45 Uplink port can be
cascaded to a hub by using straight-through cable.
