Setting Up the Compaq ProLiant Clusters HA/F100 and HA/F200 3-11
Ethernet Direct Connect Using a Private Hub
An Ethernet hub requires standard Ethernet cables; Ethernet crossover cables
will not work with a hub. Follow these steps to cable the server interconnect
using an Ethernet hub:
1. Connect the end of one of the Ethernet cables to the interconnect
(Ethernet) card in Node1.
2. Connect the other end of the cable to a port in the hub.
3. Repeat steps 1 and 2 for the interconnect card in Node2.
IMPORTANT: Place the cable into the interconnect cards and not into the Ethernet
connections used for the network clients (the LAN).
ServerNet Direct Connect
If you have chosen the Compaq ServerNet option as the server interconnect for
your ProLiant Cluster, you will need the following:
Two ServerNet PCI adapter cards
Two ServerNet cables
Follow these steps to install the ServerNet interconnect:
1. Connect one end of a ServerNet cable to connector X on the ServerNet
card in Node1.
2. Connect the other end of the ServerNet cable to connector X on the
ServerNet card in Node2.
3. Connect the two ends of the second ServerNet cable to the Y connectors
on the ServerNet cards in Node1 and Node2.
IMPORTANT: Fasten the cable screws tightly. A loose cable could cause an unexpected
fault in the interconnect path and potentially cause an unnecessary failover event.
ServerNet Direct Connect Using a Switch
Although not necessary for a two-node cluster, the use of a ServerNet Switch
allows for future growth. Refer to the Compaq ServerNet documentation for a
description and detailed installation instructions.
