HP 10Base-T Hub-16M (J3188A)
Features
Network Connections • Sixteen RJ-45 (twisted-pair) ports to connect to end nodes or other devices.
• A Media Dependent Interface (MDI) switch for Port 16 which allows you to connect
either an end node (MDI-X position) or to cascade a hub (MDI position) to the port,
using a “straight-through” twisted-pair cable in both cases. Ports 1 through 15 always
are MDI-X. Port 16 has a factory default of MDI-X, but can be toggled to an MDI state
with the adjacent push-button.
• An AUI port in the front of the hub for several types of external transceivers, including
ThinLAN, twisted-pair, and fiber-optic. The twisted-pair transceiver adds another RJ-
45 port for a total of 17 twisted-pair ports on the hub. The fiber-optic transceiver
allows you to connect your hub to a fiber-optic backbone.
Easy-to-Use Design • Hub Status LEDs showing power, activity, collisions, RPS status, fault, security and
port status provide quick, easy-to-read hub status information and troubleshooting
help.
• Metal brackets (included with the hub) that can be easily attached to the hub for
mounting the hub in a standard 19-inch telco rack.
Standards-Based
Compatibility • IEEE 802.3 Type 10Base-T standard compatibility to support both 802.3 and Ethernet
networks.
• Advanced embedded SNMP agent code enabling the hub to be managed remotely
from a network management station that supports Simple Network Management
Protocol (SNMP) over IP (using the configured IP address) or Novell NetWare (IPX).
The agent code also provides HP EASE (Embedded Advanced Sampling Environment),
which samples network data for enhanced diagnostics from a network management
station.
Other Features • Extended hub management capabilities , providing a full set of management
commands that can be executed from an ASCII console session. These are described
later in this document in chapter 3, “Managing the Hub.”
• An RS-232 serial port that provides out-of-band management access including:
– An ASCII console to configure, monitor, and troubleshoot the hub.
– Variable baud rates on the hub’s out-of-band management RS-232 port, and
automatic sensing of the selected baud rate when connecting to a terminal device.
– Full V.22bis modem line control for remote out-of-band management access to the
hub.
– Updatable firmware that enables enhancements to be downloaded either from a
computer attached to the out-of-band management port or over the network.
• A Redundant Power Supply (RPS) connector that enables an RPS to be connected to
the hub, providing an alternative redundant power source.
• Advanced integrated design including an Intel i960 RISC processor, 1 megabyte RAM,
and 512 kilobytes of flash EEPROM for configuration and future upgrade capabilities.
