The IBM 2212 has a number of light-emitting diodes (LEDs) that indicate how the unit is functioning. The following sections describe what each LED indicates.
If you have a high-performance system card or a Model x5x, the 4-port WAN PMC Mezzanine, one PCI Mezzanine Card (PMC) adapter slot, each WAN port, and the system card have their own set of green and yellow LEDs. The compact flash and hard drive each have a yellow status LED.
If you have a base system card, the PCI Mezzanine Card (PMC) adapter slot, each integrated WAN port, and the service port on the system card have their own set of green and yellow LEDs. Additionally, the system card has a green and yellow LED for overall system card status.
During a power-on reset (POR), the green and yellow system card status and service port LEDs turn on and blink in different combinations to reflect the component that is being loaded and tested. Once the IBM 2212 has been loaded and tested successfully, the system status card green LED is lit to indicate that the device is operational2. The sections that follow reflect problems that can occur after successful load and test.
For more information about problems that can occur before or during operational code load, see page Chapter 2, "Problem Solving".

Each adapter port has LEDs to indicate the port's condition as described in the following sections.
| Note: | There are also LEDs on the rear of the IBM 2212 that indicate the status of the adapter in the corresponding slot. See Additional Slot-Status LEDs. |
