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.

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.

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) which provides a connection into a Cisco

UCS blade server; it has 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.

SD card slots are provided and one or two SD cards can be populated. If two SD cards are populated, they can be used in a mirrored

mode.

The SD cards UCS-SD-32G-S and UCS-SD-64G-S can be used to store operating system boot images or other information. Once

the server has been removed from the chassis, you can access the SD card slots by rotating the latch up so that it does not cover the
