Compaq HB 1111

Compaq HB 1111 ... comprehensive LED indicator panel simplifies installation and network troubleshooting by showing network utilization and collision levels at the hub ports.

The Compaq Hub HB1111 automatically isolates a port in the event of excessive collisions and reconnects the port when normal operation resumes. It automatically stops transmission of abnormal Ethernet frames that could cause data loss for the network. The hub recognizes and adjusts 10Base-T ports for attached cable assemblies which may be wired with incorrect polarity on the receive pair. This device enables network connections using 10Base-T twisted-pair cable. It lets you connect the HB1111 hub to another HB1111 or compatible hub using the hub's uplink port. You can connect the hub to 10Base2 (BNC) cabling. It conforms to IEEE 802.3 repeater specification, as well as the 10Base-T and 10Base2 standards.
