Page 16: Connecting The Hub System
Connecting the Hub System The HP 100Base-T Hub 8 has 8 RJ-45 ports and 1 RJ-45 cascade port. The ports allow you to make connections to devices such as a workstation or server. You can also cascade to another compatible hub or switch by con- necting an MDI port on one device (e.g., port 8MDI on this hub) to an... -
Page 17: Making A Connection Via The Mdi Cascade Port
Every 100Base-T hub (repeater) adds a small propagation delay to the packet, which can be equated to a certain number of bit times. The propagation delay (repeater delay) of the HP 100Base-T Hub 8 is 80 bit times, or a cable equivalent length of 72 meters. -
Page 18: Providing Power To The Hub
Providing Power to the Hub 1. Plug the adapter’s power cord into the hub’s receptacle. 2. Plug the AC adapter into an AC power source. When installing the HP 100Base-T Hub 8, note that the AC outlet must be located near the equipment and should be easily accessible. -
Page 19: Verifying System Operation
HP 100Base-T Hub 8 Installation and Reference Guide Verifying System Operation 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 up for the corre- sponding port. -

Page 25: Port Status Display
HP 100Base-T Hub 8 Installation and Reference Guide For example, if network utilization reaches 1%, the LED labeled 1% will light up. However, if network utilization rises above 1% (e.g., 12%), the LED labeled 12 and all the other LEDs before it (i.e., 1 and 6) will also light up in rapid succession. - Page 26 HP 100Base-T Hub 8 Installation and Reference Guide Troubleshooting: If the Link LED does not light up when a device is connected to its corresponding port, check that both the hub and connected device are powered on. Check that the cable length does not exceed 100 meters. You should have standard, straight-through cables and not crossover or other specialized cables.
