Cisco UCS B200 M3 Blade Server Installation and Service Note
OL-26624-01
LEDs
Server LEDs 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.
