Warning

ELECTROCUTION HAZARD!

DANGEROUS VOLTAGES ARE PRESENT THROUGHOUT THE SYSTEM CABINET WHEN POWER IS APPLIED.

REFER TO Lockout / Tagout for System Cabinet PDU Main Breaker .

Notice

Follow this procedure for removing power to the ICN chassis. Failure to properly power down ICNs may result in premature ICN failure.

Notice

Do not turn power off to the ICNs using the power button on the front panel. The ICNs have software running on disk drives that may become corrupted if not powered down properly.

Overview

About this task

This procedure documents the proper methods of shutdown for the Dell R-620/630 ICN. NOTE: The ICN module is automatically powered on when the host computer at the GOC is powered on. There is no need to switch the ICNs on individually.

Power Down from Root Level

About this task

If the application software is down, you can power down the ICNs using command line at the root level.

Procedure

Log into the application using the root login.
In the xterm window, type: /etc/init.d/poweron_vres stop and press Enter.
The ICN(s) should turn off after one minute.

Power Off ICNs Manually

Procedure

Notice

If the browser or the command line are not accessible, the ICNs must be powered off manually. Try this method before powering off the GOC. This is the preferred method because it does not corrupt the files on the hard drive.

If the OS freezes or is not responding, then the soft method did not work properly. In this case, hold the power button down for six seconds to force the power off.

For Dell ICN momentarily press the power button. The green LED is also the power button.

Switch On ICNs from VRE Power Control

Procedure

On the Common Service Desktop, go to Utilities > Toolbox > VRE > Power Control. Click POWER ON ICN1 for the selected ICN. The new ICN is automatically powered on.

Note: The Dell ICN will display the boot status on the LED readout, which is located on the front panel of the ICN.
To power on the ICNs from the xterm command line, type: /etc/init.d/poweron_vres start and press Enter.
