Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide
To ensure that it is fully operational, the switch processes a series of tests during
power‐up or a restart (Power‐On Self‐Test, or POST). These tests may take up to
two minutes to complete. The Lenovo Flex System Chassis Management Module
(CMM) reads the test results and displays them for you. During normal operation,
these tests are completed without error, and the green switch Power LED is lit.
However, if the switch fails POST, the yellow Error LED on the switch and the
system‐error LED on the chassis are lit. An event is stored in the event log in the
system status panel of the CMM. The specific failure is displayed on the system
status I/O module panel of the CMM.
Note:
For the locations and descriptions of the switch LEDs, see "Locating the
Information Panels, LEDs, and External Ports" on page
32.
