HP 10BaseT Hub-16M

This chapter provides information on the Hewlett Packard (HP) 10BaseT Hub-16M. The information in this chapter is organized into the following sections:

Product Overview

The HP 10BaseT Hub-16M combines cost-effective LAN connectivity, security, and integrated management with Cisco IOS technologies. This 10-Mbps shared hub is the ideal complement to Cisco's Catalyst 1900 series and Catalyst 2820 series Ethernet switches for small- to medium-sized businesses and enterprise branch offices.

The HP 10BaseT Hub-16M has 16 10BaseT ports and one AUI port. One of the 10BaseT ports can be configured as either an MDI or MDI-X port through a user-selectable switch on the front panel.

The HP 10BaseT Hub-16M has built-in SNMP management, hub level and port level security, and support for Cisco Discovery Protocol (CDP) and StackMaker MIB. The hub can be monitored and managed graphically using CiscoWorks Windows, or via Telnet and out-of-band console. The HP 10BaseT Hub-16M also supports the optional external Cisco Redundant Power System (RPS).

Table 116 lists a summary of features for the HP 10BaseT Hub-16M, and Table 117 lists the environmental specifications.
