100Mbps. If the connected device does not positively indicate that it is capable of 100Mbps speed, then the operation on that DS80F and DS80C port will be at 10Mbps. Of course, the auto-negotiation technique, on ports #3 to 8, is only for 10/100 speed, and does not provide for any full-duplex operation. - Page 13 Ports 1SW and 2SW (the switched ports) have a common “F - H” user-selectable manual switch. When set in the “F” position, it causes full-duplex mode to be advertised for the standard 802.3u auto-negotiation session on RJ-45 ports, and for the fiber port, it forces full- duplex mode at 100Mb.

Page 14: Features And Benefits
Small enclosure enables use in offices, labs and classrooms The compact packaging of Magnum DS80F & DS80C’s allows them to be installed in offices and labs, or virtually any workspace location within reach of a standard AC wall outlet. - Page 15 Magnum DS80F & DS80C Dual-speed Stackable Hubs Applications The DS80F & DS80C are designed to bring future-proof fiber connectivity and highly used copper connectivity to small user groups in offices, classrooms and labs. Example 1. Magnum DS80F In this example, a Magnum DS80F Personal Hub serves a small office with multi-server and mixed-speed requirements.
- Page 16 Figure 2.6.1: Two DS80C connects together to provide 10Mbps and100Mbps network with In this example, two of the Magnum DS80C Personal Hub cascaded together to serve a small office with multi-server, print server, internet access and mixed-speed requirements. The users operate at 100Mb as well as at 10Mb and utility devices (such as print servers) run at 10Mbps.

Locate an AC receptacle that is within six feet (2 meters) of the intended Magnum DS80F & DS80C site. The rugged metal case of the Magnum DS80F & DS80C will normally protect it from accidental damage in a lab or workplace setting. Maintain an open view of the top surface to visually monitor the status LEDs. -
Page 18: Connecting Ethernet Media
Connecting Ethernet Media The Magnum DS80C Dual-Speed Personal Hub can be connected to two media types i.e. 100BASE-TX and 10BASE-T, however, DS80F can be connected to the following three media types: 100BASE-TX, 10BASE-T and 100BASE-FX. CAT 5 cables should be used when making 100BASE-TX connections. -

Link Pulse (FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to the DS80F or DS80C, it may be necessary to reload the NIC drivers on the user device if the NIC has been communicating with a protocol other than 100BASE-TX (such as 10BASE-T). When 100Mb operation is agreed and in use, the SPEED LED is illuminated steady ON. - Page 21 5V, 2.0 amps is supplied with each unit. The small DC power cord from the power supply plugs into the matching rear power jack of the DS80F and DS80C Personal Hubs. When the power is applied, the green PWR LED will illuminate.

Magnum DS80F & DS80C Dual-speed Stackable Hubs OPERATION - the function and operation of the Magnum DS80F and DS80C hubs. Dual-speed functionality, and switching The Magnum DS80F and DS80C Personal Hubs provides two N-way switched ports (one of which may be 100Mb fiber) and six dual-speed half-duplex ports. The architecture supports a few users at 10/100Mbps, and a high speed up-link and/or server port typically at 100Mbps full-duplex. -
Page 23: Auto-Negotiation And Speed-Sensing
When a RJ-45 cable connection is made, and each time when a LINK is enabled, auto- negotiation takes place. The DS80F or DS80C advertises it capability for 10 or 100 Mbps speed, and the device at the other end of the cable should similarly advertise / respond and both sides will agree to the speed being used. -
