Universal Serial Bus (USB) port problems

vFollow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

vSee the Hardware Maintenance Manual to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU).

vIf an action step is preceded by “(Trained service technician only),” that step must be performed only by a Trained service technician.

Symptom

Action

A USB device does not work.

1. Run USB diagnostics (see “POST” on page 142).

 

2. Make sure that:

vThe correct USB device driver is installed.

vThe operating system supports USB devices.

vA standard PS/2 keyboard or mouse is not connected to the server. If it is, a USB keyboard or mouse will not work during POST.

3.Make sure that the USB configuration options are set correctly in the UEFI Setup Utility program (see “Using the Setup Utility” on page 116 for more information).

4.If you are using a USB hub, disconnect the USB device from the hub and connect it directly to the server.

Video problems

See “Monitor problems” on page 151.

EasyLED

EasyLED is a system of LEDs on various external and internal components of the server. When an error occurs, LEDs are lit throughout the server. By viewing the LEDs in a particular order, you can often identify the source of the error.

When LEDs are lit to indicate an error, they remain lit when the server is turned off, provided that the server is still connected to power and the power supply is operating correctly.

Before working inside the server to view EasyLED LEDs, read the safety information in “Safety” on page vii and “Installation guidelines” on page 39.

If an error occurs, view the EasyLED LEDs in the following order:

1. Look at the operator information panel on the front of the server.

vIf the information LED is lit, it indicates that information about a suboptimal condition in the server is available in the IMM system event log or in the system-error log.

vIf the system-error LED is lit, it indicates that an error has occurred; go to step 2.

The following illustration shows the operator information panel.
