
When the power is supplied to both CPU/IO modules at about the same time, 'CPU/IO module 0' is
recognized as a primary module. In order for 'CPU/IO module 1' to be recognized as a primary module,
connect the power cord to CPU/IO module 1 first, wait for a certain amount of time (15 seconds at least),
and then connect the power cord to CPU/IO module 0.

If a UPS is connected and you want to make CPU/IO module 1 recognized as a primary module, set the
schedule so that the power will be supplied to CPU/IO module 1 first, and then CPU/IO module 0, at least
15 seconds later.


Optional devices

We do not guarantee reproduction of copy-protected DVDs and CDs using reproduction equipment if such
disks do not comply with the relevant standards.

If this server, internal optional devices, and media used as backup devices (tape cartridges) are moved
from a cold place to a warm place in a short period of time, condensation may occur, causing malfunction
or failure when these devices are next used. To protect important stored data and assets, make sure to
wait for a sufficient period before using the server and components in the operating environment.
Reference: Time effective for avoiding condensation in winter (more than 10C difference between the
room temperature and atmospheric temperature)
Disk devices: Approximately 2 to 3 hours
Tape media: Approximately 1 day

For optional devices, we recommend you use NEC products. Even if they are successfully installed or
connected, installation of unsupported devices can cause the server to malfunction or fail. You will be
charged to repair failures or damage caused by the use of such products even if it is within the warranty
period.
