Notes on Using Your Server 1-5FOR PROPER OPERATIONObserve the following notes for successful operation of the server. Use of the server ignoring thenotes will cause malfunctions or failures of the server. CPU blade– N8400-086F/087F/088F/089F/090F CPU blade assembly can be installed in the BladeEnclosure (SIGMABLADE).– Install or remove CPU blades one by one.– 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 the CPU blade was contained at thepurchase and pack it into the package.– The CPU blade is extremely sensitive to static electricity. Make sure to touch the metalframe of the server to discharge static electricity from your body before handling theCPU blade. Do not touch the CPU blade terminals or on-board parts by a bare hand andplace the CPU blade directly on the desk.– Check and adjust the system clock before the operation if any of the followingconditions is applicable.
After carriage of device
After storage of device
After the device is entered into the pause state under the environmentalcondition enduring device operation (temperature: 10°C - 35°C, humidity:20% - 80%)Check the system clock at the rough rate of once per month. When the system clock isinstalled in a system requiring high time precision, it is recommended to use a timeserver (NTP server).If the system clock is remarkably delayed or advanced as the passage of time in spite ofadjustment, contact your service representative to ask maintenance.– Store the unit under the storage condition (temperature: -10°C - 55°C, humidity: 20% -80%, without condensation) to allow built-in devices and the unit to operate correctlyin the next operation.– Before turning off the power of a CPU blade, shut down the CPU blade correctly.– Turn on the power of each CPU blade by the use of the POWER switch or the remotepower-on after the period of 30 seconds or longer has passed from the supply of ACpower (the POWER lamp of the CPU blade goes on amber) to every power unit. Thepower of the CPU blade may not be turned on if the power-on operation is done withinthe period of less than 30 seconds from the supply of AC power. After making sure thatthe AC power is supplied to every power unit, turn on the power of each CPU blade byusing the POWER switch.– After turning off the power of a CPU blade once, turn on the power again after 30seconds have passed from the power-off.– Remove a CPU blade after turning off the power of the CPU blade.
