13.2.3 Power-on self-test
When you turn on the system, the node canisters perform self-tests. A series of tests is
performed to check the operation of components and some of the options that have been
installed when the units are first turned on. This series of tests is called the power-on self-test
(POST).
performed to check the operation of components and some of the options that have been
installed when the units are first turned on. This series of tests is called the power-on self-test
(POST).
If a critical failure is detected during the POST, the software is not loaded and the fault LED is
illuminated. To determine if there is a POST error on a canister, go to 13.2.1, “Understanding
the system state using the control enclosure LEDs” on page 524 and 13.2.2, “Understanding
the system state using the expansion enclosure LEDs” on page 529

When the software is loaded, additional testing takes place, which ensures that all of the
required hardware and software components are installed and functioning correctly.

13.2.4 Powering on using LED indicators
After installing the enclosures in the IBM Flex System Enterprise Chassis, use the following
procedure to verify the enclosure power on status using the light emitting diodes (LEDs).
procedure to verify the enclosure power on status using the light emitting diodes (LEDs).
Before you begin
Make sure that the Flex System chassis is powered on. If the IBM Flex System Enterprise
Chassis is not powered on, the enclosures are not able to power on.
Chassis is not powered on, the enclosures are not able to power on.
Observe the power on LED state for each canister in each enclosure. See Table 13-2 on
page 526 and Table 13-9 on page 532 for the power on LED states. The power on LED for
each canister must be in the blink state before the enclosures will power on.
page 526 and Table 13-9 on page 532 for the power on LED states. The power on LED for
each canister must be in the blink state before the enclosures will power on.
You might have to wait up to ten minutes after installing the enclosure in the chassis before
the power on LEDs reach the blink state and can be automatically powered on. If the
enclosure does not reach the blink state after waiting ten minutes, see IBM Flex System
V7000 Storage Node Troubleshooting, Recovery, and Maintenance Guide PDF on the CD

the expansion canister. The port shall also blink when routing updates
or configuration changes are being performed on the port
