Chapter 4: Blade Module Features

Power Button

Each blade has its own power button so that individual blade units within the enclosure

may be turned on or off independently of the others. Press the power button (#1) to turn

on the blade server. The power LED (#3) will turn green. To turn off, press and hold the

power button for >4 seconds (one second if between POST and boot-up) and the power

LED will turn orange.

KVM Button

KVM stands for Keyboard/Video/Mouse. With KVM, a user can control multiple blades

with a single keyboard/video/mouse setup. Connect your keyboard, mouse and monitor

to the USB and VGA connectors on the CMM module, then push the KVM button on the

control panel of the blade module you wish to access.

LED Indicators

Blade module LEDs are described below in Table 4-3.

KVM Connector

Alternatively, you may connect a KVM cable (CBL-0218L, with a keyboard/video/mouse

attached) to the KVM connector (#7) of the blade you wish to access. To switch to

another blade, disconnect the cable then reconnect it to the new blade.

See the Web-based Management Utility User’s Manual on your SuperBlade system

CD-ROM for further details on using the KVM function remotely.
