10BASE-T Ethernet Mini Hubs User’s Guide Introduction This User’s Guide tells you how to install the following 10BASE-T Ethernet Mini Hub models: DE-809TP (9 UTP ports) DE-809TC (8 UTP ports & 1 BNC port) Port connectors on back panel of Mini Hubs Introduction...

The Mini Hubs are the palm-size compact 10BASE-T hubs that offer all the features of standard equipment rack-mount 10BASE-T hubs, including automatic port participation, collision detection, diagnostic LED report, and hub cascading. Following is a summary of the features of the Mini Hubs: 9-port hubs.
10BASE-T Ethernet Mini Hubs User’s Guide Installation Mounting Hub on Wall The Mini Hub can be mounted on a wall. Four mounting slots are provided on the bottom side of the hub for this purpose. Make sure that the front panel is exposed to allow you to view the LEDs at work.

10BASE-T Ethernet Mini Hubs User’s Guide Connecting AC Power Adapter The Mini Hub uses an external AC power adapter. There is no power switch. The hub is powered on once the AC power adapter is connected to an AC power source and the hub’s AC power socket. &DXWLRQã...

10BASE-T Ethernet Mini Hubs User’s Guide Note that, for Mini Hub model DE-809TP, UTP port labeled “9” must be in the Normal position in order to be connectable to a station, bridge or router. To connect this port to a UTP port of a 10BASE-T hub, the port must be in the Uplink position (see section Cascading Hubs Through UTP Cable in this chapter for details).
Connecting Thin Coaxial Segment The BNC port on Mini Hub model DE-809TC is used to connect to a thin coaxial segment. Connect a T-connector to the BNC connector, then connect both ends of the T-connector to the thin coaxial cable. If the thin coaxial segment terminates at the hub, attach a 50-ohm terminator to one end of the T-connector.
10BASE-T Ethernet Mini Hubs User’s Guide Cascading Hubs Through Thin Coaxial Cable The BNC port on the Mini Hub model DE-809TC can be used to cascade hubs together. You may cascade DE-809TC hubs together through the BNC ports. You may also cascade the DE-809TC with any other IEEE 802.3 Ethernet standard 10BASE-T hubs equipped with BNC ports.
Cascading Hubs Through UTP Cable Any of the UTP ports can be used to cascade hubs together. Note that when two UTP ports of two hubs are connected together, the wires inside the UTP cable must be crossed over. See appendix A for the wire cross-over.

10BASE-T Ethernet Mini Hubs User’s Guide DE-809TC Diagnostic LEDs on front panel of Mini Hubs Collision. Blinking: Packet collision is occurring. Packet collisions are not an abnormal situation. Collisions occur when two or more computers transmit packets on the network simultaneously, and a contention takes place on the network line.

Rx (for BNC port). Blinking: Packet reception is occurring. OFF: No packet reception. Partition (for each UTP port). ON: The UTP port is being partitioned off due to excessive packet collisions. Note that the UTP cable between a hub port and a non-repeater node must contain straight-through wires (no cross-over).
AC Power Adapters The following lists the specifications of the AC power adapters supplied by D-Link for use with the Mini Hub. Your Mini Hub package may contain one of these AC power adapters. If you use an AC power adapter supplied by yourself, make sure that it complies with the output power listed below and the input power and plug (AC power specifications) of your area.
