Chapter 2 Preparations
In the ordinary operation, any cables may not be connected to a CPU blade. Proper cable(s) should be
connected to the USB, serial, and/or VGA ports on the CPU blade in the following cases:
Using a Flash FDD with the server installed in the N8405-016F/016AF/016BF/040F/040AF Blade Enclosure
Performing maintenance work
Updating BIOS and firmware
Use K410-150(00) SUV cable for connection of CPU blade. (K410-150(00) SUV cable is a standard accessory
for the Blade Enclosure (SIGMABLADE)).
Important
The K410-150(00) SUV cable has the USB, serial interface, and monitor connectors at the ends. Connect a
proper device at each of the ends.
Important
Do not use an external DVD-ROM drive connected via the K410-150(00) SUV
cable to install an operating system.
Use the internal DVD-ROM drive of Blade Enclosure to install an operating
system.
To USB devices
To CPU blade
To connect a peripheral or interface cable provided by a vendor other than
NEC (or third party) to the CPU blade, make sure that the device is available for
the CPU blade. Some third party devices are not available for the CPU blade.
The serial port connector cannot be directly connected with the leased line.
Do not connect/disconnect the SUV cable or add/remove the USB device until
the operating system starts running.
To connect/disconnect the SUV cable or add/remove the USB device after OS
startup, follow restrictions of operating system.
If the device having serial interface is connected, first power off the CPU blade
and destination device, and remove the power cord from the destination device
before connecting/disconnecting SUV cable or serial cable. Failure to follow it
may cause the devices to be defected due to the potential difference between
them.
The USB device may not work correctly in USB 2.0 High Speed mode
depending on type of USB device or cable length. In such a case, use a shorter
cable, or use a USB hub that supports USB2.0 High Speed mode.
