iLO Service PortiLO Service Port
iLOiLO Service Port Service Port
When you have physical access to a server, you can use the Service Port to do the following:
Download the Active Health System Log to a supported USB flash drive.
When you use this feature, the connected USB flash drive is not accessible by the host operating system.
Connect a client (such as a laptop) with a supported USB to Ethernet adapter to access the following:
iLO web interface
Remote console
iLO RESTful API
CLI
When you use the iLO Service Port:
Actions are logged in the iLO event log.
The server UID flashes to indicate the Service Port status.
You can also retrieve the Service Port status by using a REST client and the iLO RESTful API.
You cannot use the Service Port to boot any device within the server, or the server itself.
You cannot access the server by connecting to the Service Port.
You cannot access the connected device from the server.

When the four LEDs described in this table flash simultaneously, a power fault has occurred. For more information, see Front
panel LED power fault codes.
If the health LED indicates a degraded or critical state, review the system Integrated Management Log (IML) or use HPE iLO to
review the system health status.
Facility power is not present, power cord is not attached, no power supplies are installed, power supply failure has occurred, or
the front I/O cable is disconnected.

The UID LED is used to locate a particular server when it is deployed in a dense rack with other equipment. Activating the UID LED
helps an on-site technician to quickly identify a server for maintenance tasks.
Using the UID button to view the Server Health SummaryUsing the UID button to view the Server Health Summary
PrerequisitesPrerequisites
An external monitor is connected.
In the iLO web interface, the Show Server Health on External Monitor feature is enabled on the Access Settings page.
About this taskAbout this task
You can use the UID button to display the iLO Server Health Summary screen on an external monitor. This function works both when
the server is powered on or off. Use this feature for troubleshooting if the server will not start up.

CAUTION:CAUTION: Press and release the UID button. Holding it down at any time for more than five seconds initiates a graceful
iLO reboot or a hardware iLO reboot. Data loss or NVRAM corruption might occur during a hardware iLO reboot.
ProcedureProcedure
1. Press and release the UID button.
The Server Health Summary screen is displayed on the external monitor. For more information, see the iLO troubleshooting guide:
HPE iLO 6 Troubleshooting Guide from the https://www.hpe.com/support/ilo6https://www.hpe.com/support/ilo6.
2. Press the UID button again to close the Server Health Summary screen.

Display device setupDisplay device setup
Display device setupDisplay device setup
This server supports both VGA port and DisplayPort 1.1a. Before connecting a display device to this server, review the information
below.
Whenever possible, use the same display connection type. For example, if your PC or monitor only has a VGA output, connect it to
the server VGA port. Use of any kind of adapter or converter cable or dongle might lead to decreased display quality or a lag over
the connection.
DisplayPort connection: When connecting an HDMI or DVI display to the DisplayPort, use an active type adapter. Passive type
adapter—marked with the DP++ symbol—is not supported.
Display output modes:
If you connect two display devices to the VGA port and DisplayPort, the same image is shown on both devices—screen
mirroring mode.
The embedded video controller in the iLO 6 chipset does not support dual display or screen extension mode. To enable dual
display mode, install a compatible PCIe graphics card that supports this feature in the expansion slot.
