Component LED Verification. Alcatel-Lucent 7750 SR-a8, 7750 SR-a4

Powering Up, Initializing, and Configuring

Step 1.

To initiate the boot process, plug the male end of the power cord into a 3-terminal, single-phase power source that provides power within the acceptable range, as described in

Site Preparation on page 47 .

Step 2.

Check that the LED on each PSU is green. A green LED indicates that the AC standby and main power supply outputs are operating within specification. If the

LED is off, there is no power input. Refer to

7750 SR-a AC PSU LED and

Connectors on page 138

for more information.

To power-up a DC powered system:

Step 1.

Turn on the power at the remote power sources to initiate the boot process.

Step 2.

Check that the LED on each PSU is green. A green LED indicates that the DC standby and main power supply outputs are operating within specification. If the

LED is off, there is no power input. Refer to

7750 SR-a –48 VDC PSU LED and

Connectors on page 139

for more information.

Component LED Verification

To verify that the components power up correctly:

Step 1.

Verify that the system is initializing.

The system searches the CF card on the CPM for the boot.ldr

file (also known as the bootstrap or boot loader file).

The Status LED on the CPM-a slowly blinks green during initialization.

After initialization (approximately 30 s), the Status LED on the active CPM turns solid green to indicate that the CPM boot/load process is complete and that the

CPM-a is operational as the primary CPM.

The Status LED on the inactive secondary CPM-a rapidly blinks green to indicate that the CPM-a boot/load process is complete and that the CPM-a is operational as the secondary CPM-a.

If the LEDs do not operate as described above, or if they blink and turn off, refer to

Troubleshooting Initial Startup on page 134

.

Step 2.

Verify the operational status of the router components by checking all the LEDs on the CPM-a, IOM-a, fan tray and MDA-a components.
