ECG078/0698 TECHNOLOGY BRIEF (cont.) ... Redundant Network Interface Controller Technology Compaq's Redundant Netelligent NIC technology allows two similar NICs to share a single instance of device driver code. One NIC becomes the active network controller and the other NIC acts as a standby controller. If the active NIC fails, the network traffic can be switched automatically to the standby NIC. This redundancy eliminates the NIC or cable as a single point of failure. With PCI Hot Plug technology, the failed NIC can be replaced without shutting down the system. Thus, the end-user can have continuous service and the administrator can greatly reduce both planned and unplanned downtime. Note: Software that supports a redundant NIC configuration is available on the Compaq Support Software CD that ships with the server. The ProLiant 7000 supports a Netelligent dual-port 10/100 TX PCI Network Interface Controller (NIC). The NIC has two ports for 10BaseT or 100TX Ethernet. The ports are seen as two separate local area networks LANs, both supporting full-duplex Ethernet (20 Mb/s) and Fast Ethernet (200 Mb/s). If only one of the ports is used, a terminator plug is provided for the unused port. Redundancy is also available across the two ports with one NIC. Redundant Hot-Plug Fans The ProLiant 7000 has two primary hot-plug fans (external) and two redundant fans (internal) for the processor and memory section. The pair of primary hot-plug fans for the processor and memory section is enclosed in a single fan unit (Figure 6). The primary hot-plug fans spin under rotor control; while the internal, redundant fans spin freely in the server airflow because they are not required for cooling. Should the primary fan unit fail, the redundant fans start automatically. The hot-plug primary fan unit can be easily removed by means of a single thumbscrew. The hotplug LEDs indicate the status of the fans: Green indicates the fans are functioning properly, and amber indicates the fans have failed.

Redundant Network Interface Controller Technology
Compaq’s Redundant Netelligent NIC technology allows two similar NICs to share a single
instance of device driver code.
One NIC becomes the active network controller and the other NIC
acts as a standby controller.
If the active NIC fails, the network traffic can be switched
automatically to the standby NIC.
This redundancy eliminates the NIC or cable as a single point
of failure.
With PCI Hot Plug technology, the failed NIC can be replaced without shutting down
the system.
Thus, the end-user can have continuous service and the administrator can greatly
reduce both planned and unplanned downtime.
Note:
Software that supports a redundant NIC configuration is available on the Compaq Support
Software CD that ships with the server.
The ProLiant 7000 supports a Netelligent dual-port 10/100 TX PCI Network Interface Controller
(NIC).
The NIC has two ports for 10BaseT or 100TX Ethernet.
The ports are seen as two
separate local area networks LANs, both supporting full-duplex Ethernet (20 Mb/s) and Fast
Ethernet (200 Mb/s).
If only one of the ports is used, a terminator plug is provided for the unused
port.
Redundancy is also available across the two ports with one NIC.
Redundant Hot-Plug Fans
The ProLiant 7000 has two primary hot-plug fans (external) and two redundant fans (internal) for
the processor and memory section.
The pair of primary hot-plug fans for the processor and
memory section is enclosed in a single fan unit (Figure 6).
The primary hot-plug fans spin under
rotor control; while the internal, redundant fans spin freely in the server airflow because they are
not required for cooling.
Should the primary fan unit fail, the redundant fans start automatically.
The hot-plug primary fan unit can be easily removed by means of a single thumbscrew.
The hot-
plug LEDs indicate the status of the fans:
Green indicates the fans are functioning properly, and
amber indicates the fans have failed.
