Cisco UCS B200 Blade Server Installation and Service Note
OL-22473-02
LEDs
The LED indicators indicate whether the blade server is in active or standby mode, the status of the
network link, the over all health of the blade server, and whether the server is set to give a flashing blue
beaconing indication. See
Table 1
for details.
The removable hard disks also have LEDs indicating hard disk access activity and hard disk health.
Buttons
The Reset button is just inside the chassis and must be pressed using the tip of a paper clip or a similar
item. Hold the button down for five seconds and then release it to restart the server if other methods of
restarting are not working.
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.
