Supporting HP TeachNow, v 1.1 update

HP ProCurve 1810G 24 Port Switch

Suspected hardware issues elevate to 2LS. The switch is an HP ProCurve product, not a PSG product and switch

hardware issues are handled by ISS. However, since the switch function is critical to the initial installation of HP

TeachNow, PSG should provide basic guidance on how to perform an initial configuration including:

 Verifying hardware function

 Setting flow control

 Configuring switch IP addressing

It is relatively easy to determine whether there is a switch

hardware issue by examining the switch front panel. The

front panel includes a Locator LED (triggered from the switch

web console to make it easy to identify a particular switch),

and LEDs to indicate power, faults, activity, duplex mode,

and speed.

• The power and fault LEDs apply to the overall

operation of the switch.

• Activity, mode, and speed LEDs are associated

with each port.

If the power LED is on and the fault LED is off, then the switch powered on successfully. The switch hardware is not the

likely issue.

The HP ProCurve 1810G switch uses a web-based management interface. The switch does not have a dedicated console

port. You use a web browser to configure the switch. The default 1810G IP address is 192.168.2.10 with a

255.255.255.0 subnet mask. You must use a system that is attached to the same subnet as the switch to access the web

interface.

To configure the switch for TeachNow:

Set flow control

• Connect a PC to any port on the switch.

• Record the PC’s original IP address

• Given that the PC must be on the same TCP/IP subnet, change its IP address to 192.168.2.11 and subnet

mask 255.255.255.0.

• Open a web browser on the PC and type http://192.168.2.10 in the address bar.

• When you are prompted for password, click log on (there is no default password).

• Click the Switching tab on the left then select Flow Control.

• Select Enable Flow Control then click Apply.

A dialog box displays “Warning: Flow control Mode change will cause active links to momentarily go down and turn

active again. Do you wish to continue?” Click OK to continue.

Note: Flow control is important for HP TeachNow to ensure that the transmission to/from the client to the TeachNow

server is completely reliable. Since the client is using a virtual disk on the server for its storage and for the OS image, the

performance of the client itself depends on this high speed network link. The ProCurve 1810G switch was selected for

this solution because it is reasonably priced and provides enterprise-class reliability and functions – including functions

such as Flow Control.
