Supporting HP TeachNow, v 1.1 update

B: Hardware troubleshooting considerations

Back to Appendices

Back to document index.

This appendix contains TeachNow-related T/S considerations for the three main hardware components in the HP

TeachNow solution. The available topics are:

• HP ProLiant ML110 G6

• HP ProCurve 1810G 24 Port Switch

• HP st5742/st5747

HP ProLiant ML110 G6

Network connection

The HP ProLiant ML110 G6 has two RJ45 network connectors on the rear of the chassis but only one will work with

TeachNow.

• The top right RJ45 connector MUST BE USED to connect the TeachNow server to the local LAN (the

ProCurve 1810G switch). This port connects to the NIC that the OS recognizes.

• The RJ45 connector on the bottom left connects to the iLO (integrated Lights Out) management component

in the server. iLO allows remote testing and diagnosis of the core server hardware even if the system itself is

unable to boot. This connector is NOT USED to connect the server to its LAN.

The server will not be accessible if the customer uses the wrong RJ45 connector to attach the server to the switch. Clients

will not be able to boot and the Teacher system will not be able to connect to the TeachNow application.

the basic network installation.
