NonStop NS-Series Operations Guide (H06.12+)

Powering On a System
Powering on a system delivers AC power to the system cabinets. Fans on the processor switches,
processor Blade Elements, IOAM or VIO enclosures, and disk drive enclosures start turning, and
air begins to circulate through the components. After the fans start to operate, most other system
components begin to power on.
Status light-emitting diodes (LEDs) on the system components light during a series of power-on
self-tests (POSTs). Any of the LEDs can become lit briefly during the POSTs. After all the POSTs
finish successfully, which might take up to 10 minutes, only the green power-on LED on each
component in the system enclosures should remain lit. For more information about the LEDs,
refer to Using the Status LEDs to Monitor the System on page 3-20.
The method you use to power on the system depends on whether the system is in a low power
state or completely powered off:
• “Powering On the System From a Low Power State” (page 156)
• “Powering On the System From a No Power State” (page 156)
Powering On the System From a Low Power State
1. Log on to the OSM Low-Level Link.
2. From the tree pane, right click the system and select actions.
3. Select Power On System.
4. If your maintenance LAN is not configured with the dynamic name service (DNS) or does
not have reverse look-up, you must perform a hard reset of the maintenance entities (MEs)
in each p-switch or IOAM enclosure, or the integrated maintenance entities (IMEs) in each
VIO enclosure*:
a. From the Log On to HP OSM Low-Level Link dialog box, select Logon with Host Name
or IP Address.
b. Enter the IP address of:
• a maintenance entity (ME) in a p-switch
• an ME in an IOAM enclosure
• an IME in a VIO enclosure
c. Expand the tree pane to locate the ME or IME.
d. Right-click that ME or IME object and select Actions.
e. Select Hard Reset.
f. Click Perform Action.
g. A message appears:
Hard Reset action will make the current session lost. After OSM Low-Level Link completes Hard Reset
action, it will log you off. Do you really want to reset the ME?
h. Click OK.
i. Close the Low-Level Link.
j. Repeat these steps for the other ME(s) or IME.
* For Integrity NonStop NS14000, NS1200, and NS1000 systems, there are no p-switches. Instead,
there are either two MEs in the IOAM enclosure or an IME in each of the two VIO enclosures.
Powering On the System From a No Power State
To power on the system when you first receive your system, you refer to the NonStop NSxxxx
Hardware Installation Manual for your Integrity NonStop NS16000 series, NS14000, NS1200, or
NS1000 server. To power on the system subsequently:
