Cisco UCS B22 Blade Server Installation and Service Note
OL-27513 -01
The power button and LED allows you to manually take a server temporarily out of service but leave it
in a state where it can be restarted quickly. If the desired power state for a service profile associated with
a blade server or an integrated rack-mount server is set to "off", using the power button or Cisco UCS
Manager to reset the server will cause the desired power state of the server to become out of sync with
the actual power state and the server may unexpected shutdown at a later time. To safely reboot a server
from a power-down state, use the Boot Server action in Cisco UCS Manager.
Connectors
A console port is provided to give a direct connection to a blade server to allow operating system
installation and other management tasks to be done directly rather than remotely. The port uses the KVM
dongle device included in the chassis accessory kit.
The KVM cable (N20-BKVM shown in Figure 2) provides a connection into a Cisco UCS blade server,
providing a DB9 serial connector, a VGA connector for a monitor, and dual USB ports for a keyboard
and mouse. With this cable you can create a direct connection to the operating system and the BIOS
running on a blade server.
