Replacing Storage Devices |
This chapter describes the removal and installation procedures for Sun Ultra 45 or Ultra 25 workstation storage devices.
The procedures described in this chapter are written for workstation service providers and system administrators.
This chapter contains the following topics:
Caution - To prevent equipment damage, review the safety information in Preparing to Replace Componentsbefore you perform any replacement procedure. Additional cautions, warnings, and instructions are provided in the Sun Ultra 45 and Ultra 25 Workstations Safety and Compliance Guide, 819-2785. The document is available from:

The workstation supports up to four hard drives, either serial ATA (SATA), or serial attached SCSI (SAS). The hard drives slide into the hard drive bay and use standard Sun hard drive mounting brackets.
Note - Sun does not support mixed SAS and SATA hard drives. All four installed hard drives must be the same type. |
Caution - The Sun SATA and SAS hard drive brackets are gray. To prevent damage to the connectors, do not insert any other color of hard drive into Sun Ultra 45 or Ultra 25 workstations. |
The hard drives are labeled HDD0 through HDD3. The default boot drive is HDD0 (FIGURE 4-1).
TABLE 4-1 lists the hard drive specifications.
250GB, 7,200 rpm, 3.5 inch, (gray bracket)
80GB, 7,200 rpm, 3.5 inch, (gray bracket) for Ultra 25 workstation. |

1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.
Refer To Powering Off the Workstation.
2. Press the hard drive release button to release the hard drive handle (FIGURE 4-1).
3. Grasp the hard drive handle and pull the hard drive out of the hard drive bay.
4. Set the hard drive aside on an antistatic mat.
1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.
Refer to Powering Off the Workstation.
Note - The default boot device is installed in HDD0 (drive 0). Be sure to install the boot disk in HDD0, unless you have changed the boot device parameters. |
2. Remove the new hard drive from its packaging.
Caution - The Sun SATA and SAS hard drive brackets are color-coded gray. To prevent damage to the connectors, do not insert any other color of hard drive into Sun Ultra 45 or Ultra 25 workstations. |
3. Install the hard drive (FIGURE 4-1).
4. Slide the hard drive into the hard drive bay.
5. Close the latch on the hard drive until it clicks and is secure.
6. If you are finished working, reassemble the workstation, power on the workstation, and verify the hard drive installation.
See Finishing Component Replacement.
Note - Boot the system with the -r option, so that the Solaris Operating System can reconfigure itself for the new component. See Finishing Component Replacement. |
This section describes removal and installation of the hard drive backplane, the signal cable, and the power cable.
1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.
Refer to Powering Off the Workstation.
3. Remove long PCI cards if they are covering the hard drive backplane cables.
Refer to Removing a PCI Card. Set these components onto an antistatic mat.
4. Disconnect the cables from the following connectors
5. Using a No. 2 Phillips screwdriver, remove the two screws from the hard drive backplane.
1. Remove the new hard drive backplane and cables from the packaging.
2. Using a No. 2 Phillips screwdriver, replace the two screws for the hard drive backplane.
3. Reconnect the cables to the following connectors:
4. Inspect the cabling to verify that the signal and power cables are both secure at the backplane and the motherboard.
5. If you removed any long PCI cards, replace them.
Refer to Installing a PCI Card.

This section describes removal and installation of the I/O module. The I/O module contains the DVD-dual drive, the audio USB board with speaker, USB and audio connectors, and the Power button and LED.
1. Power off the system and attach an antistatic wrist strap. Open and position the chassis, and remove the access panel.
Refer to Powering Off the Workstation.
2. Open the I/O cable clip at the top of the chassis (FIGURE 4-3).
3. Disconnect the following cables:
New cables are provided with the DVD-dual drive and the I/O module.
If you need to remove a long PCI card to access the USB cable, refer to Removing a PCI Card.
4. Press the I/O module release button and pull the I/O module out the front of the chassis.
Place the I/O module on an antistatic mat.
Caution - Do not attempt to remove the bezel from the front of the I/O module. |
5. If you are only replacing the DVD-dual drive:
a. Using a No. 0 Phillips screwdriver, remove the screws holding the DVD-dual drive into the I/O module.
b. Pull the DVD-dual drive straight out the back of the removable media bay (FIGURE 4-3).
6. If you are replacing the audio USB board:
a. Remove the DVD-dual drive and set it aside.
b. Using a No. 2 Phillips screwdriver, remove the four screws that secure the audio USB board to the I/O module.
c. Pull the audio USB board straight out the back of the removable media bay (FIGURE 4-3).
1. Remove the I/O module and DVD-dual drive assembly from the packaging.
2. If you are replacing the audio USB board:
a. Install the new audio USB board into the removable media bay (FIGURE 4-3).
b. Replace all four screws that secure the audio USB board to the removable media bay.
3. Install the DVD-dual drive into the I/O module with the screws (FIGURE 4-3):
a. If you are using the old DVD-dual drive, screw the old drive into the I/O module.
b. If you are using a new DVD-dual drive, screw the new drive into the I/O module.
4. Push the I/O module and DVD-dual drive into the chassis until the module clicks (FIGURE 4-3).
5. Connect the cables to the DVD-dual drive and the audio USB board.
If you removed a long PCI card, replace it now. Refer to Section 3.5.5, Installing a PCI Card.
Note - Always use the new cables that are shipped with the DVD-dual drive or I/O module. |
