Powering On Using Led Indicators - IBM V7000 Introduction And Implementation Manual

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).
Before you begin
Observe these considerations:
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.
Observe the power on LED state for each canister in each enclosure. See Table 13-2 on
page 575 and Table 13-9 on page 581 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 the IBM Flex System
V7000 Storage Node Troubleshooting, Recovery, and Maintenance Guide PDF on the CD
shipped with your system.
Attention: Do not operate the system when the drive assemblies are missing. Drive
assemblies that are missing disrupt the airflow, which prevents the drives from getting
sufficient cooling. You must insert blank carriers into any unused drive bays.
Powering on a control enclosure procedure
Follow these steps:
1. Powering on a control enclosure
2. When the power on LEDs reach the blink state, the control enclosure is powered on
automatically. The green power on LEDs are on solid when the enclosure is powered on
successfully.
3. Verify that no faults are detected on the control enclosure after powering on. Use
Table 13-2 on page 575 to verify the state of the LEDs on the control enclosure. See the
IBM Flex System V7000 Storage Node Troubleshooting, Recovery, and Maintenance
Guide PDF on the CD shipped with your system if problems are encountered. Figure 13-2
on page 574 shows the location of the LEDs on the front of the control enclosure.
Attention: Do not continue if any faults are indicated by the LEDs.
Powering on an expansion enclosure
Follow these steps:
1. When the expansion enclosure power on LEDs reach the blink state, the expansion
enclosure is powered on automatically. The green power on LEDs are on solid when the
enclosure is powered on successfully. See Table 13-9 on page 581.
2. Use the information in Table 13-10 on page 581 to verify the state of the light emitting
diodes (LEDs) on the expansion enclosure. Verify that no faults are detected. See the IBM
Flex System V7000 Storage Node Troubleshooting, Recovery, and Maintenance Guide
PDF on the CD shipped with your system if problems are encountered.
Attention: Do not continue if any faults are indicated by the LEDs.
