To aid with problem determination, the server includes basic light path diagnostics, which are a set of
LEDs on the front of the server and inside the server that show you which component is failing. The LEDs
are shown in the following figure.

When an error occurs, the system error LED lights up. You can review the logs through the web interface
of the IMMv2 (see the "Remote management" section).
Remote management
The server contains IBM Integrated Management Module II (IMM2), which provides advanced
service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a
threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records
the error in the event log, and alerts you to the problem. Optionally, the IMM2 also provides a virtual
presence capability for remote server management capabilities.
The x3650 M4 HD offers a dedicated Ethernet port at the rear of the server for remote access to the
IMM2. Alternatively, one of the four Ethernet ports that are accessible by the operating system can be
shared with IMM2 access. This feature is enabled through the system setup in UEFI.
The IMM provides remote server management through industry-standard interfaces:
Intelligent Platform Management Interface (IPMI) Version 2.0
Simple Network Management Protocol (SNMP) Version 3
Common Information Model (CIM)

The optional IBM Integrated Management Module Advanced Upgrade is required to enable the remote
presence and blue-screen capture features. The remote presence feature provides the following
functions:
Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 23 bits per
pixel colors, regardless of the system state
Remotely accessing the server using the keyboard and mouse from a remote client
Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping
ISO and diskette image files as virtual drives that are available for use by the server
Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive
