Performing a Change Online
You can perform many changes to a NonStop S-series system online. For information
on hardware changes, application changes, and communications subsystem changes
you can perform without shutting the system down, refer to the NonStop S-Series
Planning and Configuration Guide and the Availability Guide for Change Management.
Powering On the System
When you power on a system, AC power is delivered to the system enclosures. The
fans in each enclosure start turning and air begins to circulate. After the fans start to
operate, the 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). When all the POSTs finish successfully, which might take
up to 10 minutes, the green power-on LED on each component in the system
enclosures should be lit. All LEDs can light during the POSTs, but only the green
power-on LEDs should remain lit after the POSTs finish. For more information about
the LEDs, refer to Using the Status LEDs to Monitor the System on page 3-32.
Before Powering On the System
If this is the first time you are powering on the system or if the server and system
console are not installed as indicated in this list, refer to the procedure for powering on
a system as described in the NonStop S-Series Hardware Installation Guide:
•
You must install:
°
All power-on cables
°
The emergency power-off (EPO) cables if applicable
°
ServerNet cables if your system includes multiple enclosures
°
The tape subsystem used for processor memory dumps
°
The Ethernet hub
•
The server must already be plugged in.
•
A system console must be properly connected to the system, powered on, and
running the OSM or TSM client software.
