Warranty registration card If there are any incorrect, missing, or damaged parts, contact your Compaq Authorized Reseller. If possible, retain the carton, including the original packing materials, in case you need to repack the contents and return the hub for repair. - Page 6 ......The Netelligent 1017A/B 10Base-T Hub is a 16-port Ethernet hub which features an on-board microprocessor designed to monitor network utilization, collisions, link and port partition status.
- Page 7 This chapter describes the main hub components. For easier management and control of the hub, familiarize yourself with the front panel indicators. Figure 2-1 shows the front panel of the hub where the comprehensive LED indicators, 16 RJ-45 station ports and the uplink switch are located. Figure 2-2 shows the...

Page 8: Front Panel
The LED indicator panel includes comprehensive indicators for monitoring device and network status. The LEDs on the front panel let you easily monitor the status of each port, plus the overall condition of the hub. The following sections describe the function of each indicator. - Page 9 30 and all the other LEDs before it (that is, 1, 5, and 15) light in rapid succession. These LEDs monitor the share of valid network frames transmitted by this hub within a 10Mb/s bandwidth. They provide a quick way to monitor the current...
- Page 10 1% 3% 5% 10% 15+% Collisions occur when two or more devices connected to a hub attempt to transmit data simultaneously on the network. When a collision occurs, devices pause and then re-transmit after a pseudo-random wait period. Because wait periods differ among devices, successive collisions become increasingly improbable.
- Page 11 LED pairs labeled AUI and BNC monitor the AUI and BNC ports on the back panel. The other 16 pairs are for the RJ-45 ports on the front panel of the hub. A port is temporarily partitioned when a line error or too many collisions are detected on the attached segment.

Page 12: Station Ports
To connect to another hub, you can also run straight-through twisted-pair cabling from a station port on this hub to a crossover port on another hub. However, if you must connect to another hub via stations ports at both ends of the cable, use... -
Page 13: Back Panel
It enables or disables the uplink function of Port 16. When the switch is enabled, Port 16 functions as an uplink port for connecting to another compatible hub. When the switch is disabled, Port 16 functions as a normal station port for connecting to a workstation. To enable the uplink capability, slide the uplink switch to the right (MDI). - Page 14 BNC ports, there should be at least 0.5 meters (about two feet) of coaxial cable between the two BNC ports. If the hub is at the end of an Ethernet cable, plug and lock a 50-ohm ( ) terminator to the T-type connector on the BNC port.
-
Page 15: Power Switch
......The power switch is located at the right side of the back panel. It is used to power the hub on and off. -
Page 16: Site Requirements
Leave at least 10 cm. of space at the front and back of the hub for ventilation. We recommend that you install the hub in a cool, dry area. If you plan to mount the hub in a rack, be sure you have all the required screws, brackets and tools you need for proper installation. - Page 17 10Base2 Thin Ethernet trunk. If the hub is at the terminal end of a trunk segment, then connect a 50-ohm ( ) terminator to the open end of the "T" connector. If the Ethernet BNC trunk port has no connection, plug in the BNC T-type connector and lock both ends with a 50-ohm ( ) terminator.

Page 18: Stand-Alone Configuration
Install the power cord and power on the hub. Plug the power cord into the power socket at the rear of the hub. Then connect one end of the cord to an electric outlet. Power on the hub by pressing the power switch to ON. Check the LED indicator marked PWR on the front panel. - Page 19 Verify that all attached devices have a valid connection. The hub monitors link status for each port. If any device is properly connected to the hub and transmitting a link beat signal, the Link indicator lights for the corresponding port. If valid traffic is being transmitted by the connected device, the same indicator (now referred to as the Traffic indicator) flashes to indicate network activity.

Page 20: Backbone Connection
5 unshielded twisted-pair cable, or you can connect multiple hubs through a backbone connection. You can install the 1017A/B hub in a standard wiring closet or in a workgroup. The only limitation is that all end-node devices (for example, workstations or servers) must be within 100 meters of the connected hub. - Page 21 The 1017A/B hub provides an uplink port you can use to connect to another hub. You can convert Port 16 to an uplink port by sliding the uplink switch to the right (MDI) position. When the switch is in this position, you cannot use Port 16 as a station port.
- Page 22 ......With a crossover twisted-pair cable, you can connect the 1017A/B hub to a compatible hub using any available RJ-45 port.

Page 23: Using The Bnc Port
You can use either type to link to an Ethernet backbone, depending on the media type required. The 1017A/B hub can be stacked with other hubs using the BNC port on the back panel. Through this port, you can connect hubs via thin coaxial cable (10Base2). -
Page 24: Port Connections
To connect to Thick Ethernet, attach a 10Base5 transceiver to the backbone, and run an AUI drop cable between the the hub and the transceiver. A Thick Ethernet segment can run up to 500 meters and connect up to 100 nodes. - Page 25 To control the number of hubs in a path, we recommend that you use one hub to connect to several other hubs. By using a star configuration, you can link more workstations together in a network than would be possible with a normal uplink configuration.
- Page 26 You can easily monitor the 1017A/B 10Base-T Hub using its comprehensive panel indicators. These indicators help you identify problems the hub may encounter. This section describes common problems and possible solutions. Symptom: CPU indicator displays a steady green light long after power on.
- Page 27 Be sure the media transceivers are functioning properly and the SQE test has been disabled for all transceivers attached to the hub’s AUI port. If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by implementing the new changes, one step at a time.
- Page 28 As a last resort verify the hub’s integrity with a power-on reset. Turn the power to the hub off and then on. If the problem still persists and you have completed all the preceding diagnoses, then contact your Compaq Authorized Reseller for...
