Cisco UCS B200 M3 Blade Server Installation and Service Note
OL-26624-01
The beaconing function for an individual server may get turned on or off by pressing the combination
button and LED. See Table 1 for details.
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
The console port allows 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 cable
(N20-BKVM shown in Figure 2) which provides a connection into a Cisco UCS blade server; it has a 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. A KVM cable ships standard with each blade chassis accessory kit.
