This chapter describes how to remove and install backplanes and cables in the system. For a list of part numbers for field-replaceable units (FRUs) and optional equipment, see Illustrated Parts Breakdown.
The following tasks are covered in this chapter:
The following information is also included:
1. Disconnect the base/expansion cable (P43 and P2) from the expansion backplane at connectors J0100 and J0801.

7. Remove the backplane from the system.
8. Place the expansion backplane on an antistatic mat.
9. If you are not immediately replacing the expansion backplane, install an FC-AL backplane filler panel, if you have one, on the disk cage.

b. Fasten the three Phillips screws that secure the filler panel to the backplane.
10. If you are not immediately replacing the expansion FC-AL backplane, disconnect the base/expansion cable (P42) from connector P42/J7(DISKS) on the power distribution board and from connector J0801 on the base FC-AL backplane.
11. If you are not immediately replacing the expansion FC-AL backplane, disconnect the FC-AL data cable (F and E) from connectors F(J0501) and E(J0500) on the base FC-AL backplane.
To replace the expansion FC-AL backplane, complete this task:
To reassemble the system, complete this task:
If you are not replacing this part right away, you need to perform a reconfiguration boot in order for the operating system to recognize the configuration change. See:
1. If an FC-AL backplane filler panel is installed, remove the three Phillips screws securing the filler panel to the backplane and remove the filler panel from the system.
2. Position the expansion backplane in the system against the disk cage.
Align the three screw holes on the backplane with the screw holes on the disk cage.
3. Fasten the three screws and nylon washers that secure the backplane to the disk cage.
If you are installing the expansion backplane for the first time, the nylon washers are included with the backplane kit.
4. Connect the expansion FC-AL backplane cables to the backplane.
If you are installing an expansion backplane in the system for the first time, install the following cables:
a. FC-AL data cable (A and B) to connectors A(J0201) and B(J0200) on the expansion backplane and to connectors F(J0501) and E(J0500) on the base FC-AL backplane
b. Base/expansion cable (P42) to the power distribution board at connector P42/J7(DISKS)

e. I2C cable (P20) to connector J0800 on the expansion backplane
The expansion backplane I2C cable is part of a cable assembly that includes the base backplane I2C cable that is already connected to the base backplane. The expansion backplane end of the cable is ganged with a group of cables running through the cable guides on the chassis centerplane and must be freed from the uppermost cable guide so that it can reach the expansion backplane.

6. Connect the two disk status flex circuit cables to the expansion backplane at connectors J01000 and J01001.
7. To reassemble the system, complete these tasks:

8. After installing an expansion backplane, power on the system and bring up the system up to the ok prompt.
9. Allow the system to remain at the ok prompt for at least 10 minutes to ensure that the two backplanes are loaded with the same version of firmware.
The system automatically synchronizes the firmware versions between the two backplanes.
10. After the required waiting period, boot the system to single-user mode.
11. To verify that the firmware synchronization process has completed successfully, type the following luxadm subcommand:
where enclosure-name is the enclosure name assigned to the Sun Fire V890 internal storage array--by default, FCloop. If you need to verify the enclosure name first, use the luxadm probe subcommand.
The output of the display subcommand shows the status of each SSC100 processor in the system. The following is an excerpt of sample output for a dual-backplane system.
SSC100's - 0=Base Bkpln, 1=Base LoopB, 2=Exp Bkpln, 3=Exp LoopB SSC100 #0: O.K. (9228/ 3A20) SSC100 #1: O.K. (9228/ 3A20) SSC100 #2: O.K. (9228/ 3A20) SSC100 #3: O.K. (9228/ 3A20) |
Verify that each SSC100 processor displays an O.K. status and that each displays the same firmware version in parentheses. If so, the firmware synchronization process has completed successfully. Otherwise, wait another two minutes or so and repeat this process.
Note - For more information about the luxadm utility, refer to Platform Notes: Using the luxadm Software, which is included on the Sun Fire V890 Documentation CD. |
12. Once the firmware synchronization process is complete, you can restore the system to multiuser mode.
