Note - Always grip the bezel at both ends to open it. Do not attempt to open it using a single point of grip.

2.3 Controlling Server Power

Before you remove or replace a system configuration card or DVD-ROM drive, the server must be powered down.

Tip - For detailed information on controlling server power with software, see:
http://docs.sun.com, and search for ALOM documentation.

2.3.1 Powering On--Using the On/Standby Switch

Caution - Never move the system when the system power is on. Movement can cause catastrophic disk drive failure. Always power off the system before moving it.

1. Connect the server to an AC power source.

Once connected, the server automatically goes into Standby power mode.

2. Turn on power to any peripherals and external storage devices you have connected to the server.

Read the documentation supplied with the device for specific instructions.

3. Open the front bezel.

4. Sun Fire V240 only: insert the system key into the keyswitch and set it to the Normal or Diagnostics position.

5. Press the On/Standby switch.

Verify that the LED for the On/Standby switch illuminates.

6. Sun Fire V240 only:

a. Turn the key switch to the Locked position.

This prevents anyone from accidentally powering off the system.

b. Remove the system key from the keyswitch and store it in the clip on the back of the bezel.

7. Close the front bezel.

2.3.2 Powering Off--Using the On/Standby Switch

Note - Applications running on the Solaris OS can be adversely affected by a poorly executed system shutdown. Make sure you have gracefully shut down any applications before powering off the system.

1. Notify users that the system will be powered down.

2. Back up the system files and data, if necessary.

3. (Sun Fire V240 only) Ensure that the keyswitch is in the Normal or Diagnostics position.

4. Press and release the On/Standby switch behind the front bezel.

The system begins an orderly software system shutdown.

Note - Pressing and releasing the On/Standby switch initiates an orderly software shutdown. Pressing and holding the switch for four seconds causes an immediate hardware shutdown. Whenever possible, initiate an orderly shutdown. Forcing an immediate hardware shutdown can corrupt the disk drive and cause loss of data.

5. Wait for the front panel green LED to go out.

6. Sun Fire V240 only: remove the system key from the keyswitch and store it in the clip on the back of the front bezel.

7. Close the front bezel.

2.4 Swapping a System Configuration Card Between Servers

2.4.1 Swapping a System Configuration Card Between Servers

Caution - Never remove the system configuration card while the server is booting or running the Solaris OS. Either remove power from the server, or put it into Standby mode, before removing or inserting the system configuration card.

Caution - Do not handle the system configuration card unless you need to transfer it to another system. If you need to handle it for this reason, avoid contact with the gold terminals on the underside of the card.

Caution - If you remove the system configuration card (SCC) and replace it with the SCC from a system of a different platform type, the card will be reconfigured. A message tells you when this has been done, but the system does not request confirmation before reformatting the card.

1. Power down both servers.

See Section 2.3, Controlling Server Power.

2. Open the front bezel on both servers.

See Section 2.2.2, Opening the Front Bezel.

3. Remove the cable ties that secure the system configuration cards, and remove the cards.

4. Insert the system configuration card from the old server into the new one.

5. Replace the cable tie on the new system.

6. Power on the new system.

2.5 Removing and Replacing Hard Drives

Caution - The server and hard drives contain electronic parts that are extremely sensitive to static electricity. Wear a grounded antistatic wrist strap when you carry out this procedure.

2.5.1 Removing a Hard Drive

The hard drives are hot-pluggable modules. If more than one is fitted, you can install or remove a hard drive without powering off the server or removing it from the rack.

However, you do need to make sure that no system or application software is using a hard drive when you remove it.

Note - If you intend to remove a hard drive with Solaris running, follow the instructions in Section 2.5.4, Removing a SCSI Hard Drive With Solaris Running before performing the following steps.

1. Open the front bezel.

See Section 2.2.2, Opening the Front Bezel.

2. Check that the blue indicator LED is lit on the hard drive.

The blue LED comes on when the hard drive is ready to remove.

3. Slide the catch at the front of the hard drive to the right.

This releases the handle on the front of the hard drive.

4. Pull the handle and remove the hard drive from the server by sliding it out from its bay.

2.5.2 Replacing a Hard Drive

Caution - The server and hard drives contain electronic parts that are extremely sensitive to static electricity. Wear a grounded antistatic wrist strap when you carry out this procedure.

FIGURE 2-4 Installing a Hard Drive (Sun Fire V210 Server)

Figure shows open bezel and installation of hard drive into the Sun Fire V210 server.

1. Slide the catch on the front of the hard disk to the right.

This releases a handle on the front of the hard drive. The lever must be open before you insert the hard drive. If it is not, the hard drive does not engage with the server correctly.

2. Slide the hard drive into its bay at the front of the server.

Push it in firmly until the metal lever starts to close. This indicates that the hard drive is engaged with its connector attached to the server.

3. Push the metal lever until the disk drive clicks into place.

4. Close the bezel.

If you have installed a hard drive with Solaris running, perform the steps in Section 2.5.3, Installing a SCSI Hard Drive With Solaris Running.

2.5.3 Installing a SCSI Hard Drive With Solaris Running

Before performing the instructions in this section, install the hard drive by following the instructions in Section 2.5.2, Replacing a Hard Drive.

Use the following instructions in conjunction with the cfgadm(M) man page.

1. With the new hard drive physically installed in the drive bay, log into the system as superuser and run the format command to make the disk visible to the Solaris OS.

Type the following command. The following sample output is from a system containing two hard drives.
