Storwize V3500: Quick Installation Guide
c. Connect the USB flash drive to the computer to check that the initialization
completed.
9. If the system initialization completed successfully, click Finish. If you have a
network connection to the Storwize system, the system management GUI is
displayed. If the computer does not have a network connection to the
Storwize system, go to the computer that you will use to manage the system
and start a supported browser. Direct the browser to the management address
you specified for the system.
10. Log in with user name superuser and password passw0rd.
Note: The 0 character in the password is a zero, not the letter O.
11. Follow the on-screen instructions to begin setting up your system.
Note: The other options that are available in the initialization tool are used to
recover the service IP address or the superuser password.
For operation in Network Equipment-Building System (NEBS) compliant
installations, the Storwize V3500 system can be configured to extend its operational
temperature range to meet NEBS operating temperature requirements.
Note: The Storwize V3500 system might not be able to save its cache and state
data if the power fails while it is operating within the extended temperature range.
This is because the battery capacity decreases as temperature rises. If the save of
cache and state data cannot be completed, an extended service action is required to
recover the system and data might be lost. Keep the temperature within the
normal operating range if possible, and maintain a reliable power supply.
v To extend the operational temperature range of all enclosures in the system to
meet NEBS operating temperature requirements, enter the following CLI
command:
chsystem -hightempmode on
After it is set, high_temp_mode is applied to all enclosures in the system.
v To configure the default operating temperature ranges, enter the following CLI
command:
chsystem -hightempmode off
v To determine which mode is configured, read the value of the high_temp_mode
parameter in the lssystem output.
Notes:
1. Configuring the Storwize V3500 system to be NEBS-compliant only changes the
way that the system responds to raised temperature. You must also ensure that
the way the system is racked, and the operating environment, conforms to
NEBS requirements. See "NEBS-compliant earth connection" on page 9.
