1-6 Notes on Using Your Server

FOR PROPER OPERATION

Observe the following notes for proper operation of the server. Failure to observe these notes may
cause a malfunction of the server.
CPU blade
– N8400-071AF/072AF/073AF/074AF CPU blade assembly can be installed in the Blade
Enclosure (SIGMABLADE).
– Install or remove CPU blades one at a time.
– Hold the portions covered with metal plates when a CPU blade is installed or removed.
To carry a CPU blade, put it into the case in which it was packaged during shipping.
– The CPU blade is extremely sensitive to static electricity. Make sure to touch the metal
frame of the server to discharge static electricity from your body before handling the
CPU blade. Do not touch the CPU blade terminals or on-board parts with your bare
hands or place the CPU blade directly on a desk.
– Check and adjust the system clock after:
Check the system clock once a month. It is recommended to synchronize the system
clock using a time server (NTP server) when a high degree of time accuracy is required.
If the system clock fails to maintain sychronization despite being adjusted, contact
your sales agent.
– Store the unit under storage conditions (temperature: -10°C - 55°C, humidity: 20% -
80%, without condensation) to ensure it functions correctly when it is used again.
– Before turning off the power of a CPU blade, shut it down correctly.
– Turn on the power of the CPU blade by using the POWER switch or the remote
power-on function after waiting 30 seconds or longer after supplying AC power to the
power unit (the POWER lamp of the CPU blade lights amber). The CPU blade may not
turn on if you do not wait at least 30 seconds after supplying AC power.
– After turning off the power of a CPU blade, wait at least 30 seconds before turning it
on again.
– Remove a CPU blade after turning off its power.
