1.Disconnect power from the workstation (see Predisassembly procedures on page 73).
2.Remove the side access panel (see 
Removing the side access panel on page 75).
3.Remove the airflow guide (see 
Removing the airflow guide on page 76).
ENWW Removing and installing components 91 
						

							4.Lift the drive release latch at the green label touch point,  and gently slide the filler tray out of the
chassis 
2 as shown in the following figure.
TIP:Excess power cables can be stored in the filler tray. Remove the cables before removing
the tray from the chassis.

92 Chapter 5   Replacing components ENWW 
						

							Installing a filler tray
1.Disconnect power from the workstation (see Predisassembly procedures on page 73).
2.Remove the side access panel (see 
Removing the side access panel on page 75).
3.Lift and hold the drive release latch at the green touch point 
 while sliding the filler tray into the
bay 
2. When the front of the filler tray is near its final position, release the latch, but continue to
slide the filler tray inward until the latch closes and engages the filler tray.
TIP:During installation the adjacent drive or filler may move slightly. You might have to slide and
align both devices to get the release latch to close and engage both devices.
While the tray is partially inserted, replace excess power cables in the tray for storage.

							Optical disk drive
This section describes how to remove and install an optical disk drive.
Removing an optical disk drive from the optical drive bay
1.Disconnect power from the workstation (see Predisassembly procedures on page 73).
2.Remove the side access panel (see 
Removing the side access panel on page 75).
3.Remove the airflow guide (see 
Removing the airflow guide on page 76).
4.Remove the expansion card support (see 
Removing the expansion card support on page 77).
5.Disconnect the power 
 and data 2 cables from the optical disk drive as shown in the following
figure.

							6.Lift the drive release latch at the green touch point  and gently slide the drive out of the
chassis 
2 as shown in the following figure.
Figure 5-25  Removing the optical disk drive
7.If you are not installing another optical disk drive, add a filler tray to the empty bay slot (see Installing
a filler tray on page 93).
ENWW Removing and installing components 95 
						

							Installing an optical disk drive in the optical drive bay
1.Disconnect power from the workstation (see Predisassembly procedures on page 73).
2.Remove the side access panel (see 
Removing the side access panel on page 75).
3.Remove the airflow guide (see 
Removing the airflow guide on page 76).
4.If you are adding an additional drive, remove the filler tray (see 
Removing a filler tray
on page 91).
NOTE:Unused optical bay power cables are stored in this tray.
5.Lift and hold the drive release latch at the green touch point  while sliding the optical disk drive
into the bay 
2. When the front of the drive is near its final position, release the latch, but continue
to slide the drive inward until the latch closes and engages the drive.
TIP:An optical drive longer than 175 mm (but less than 206 mm) must be installed in the middle
or bottom bay.

7.Connect the optical disk drive data cable to the next available SATA port on the system board as
shown in the following figure.
Figure 5-28  Connecting the drive cable to the system board
NOTE:If no SATA data port connector is available on the system board, check to see that all
attached SATA cables are connected to active devices. An unused device can be disconnected to
free up a SATA data port connector on the system board.
If no SATA data port connector is available on the system board, move the attached SATA storage
device data cables to the next available SAS data port connectors on the system board. See
Component locationson page 70 for connector locations on the system board.

							Notice for Blu-ray optical drives
If you installed a Blu-ray optical drive, note the following:
Blu-ray movie playback
As Blu-ray is a new format containing new technologies, certain disc, digital connection, compatibility
and/or performance issues may arise, and do not constitute defects in the product. Flawless playback
on all systems is not guaranteed. In order for some Blu-ray titles to play, they may require a DVI or HDMI
digital connection and your display may require HDCP support. HD-DVD movies cannot be played on
this workstation.
Blu-ray movie playback compatibility and update
Playing back Blu-ray HDCP (High-bandwidth Digital Content Protection) content such as commercially
distributed Blu-ray HD movies requires a fully HDCP compliant path on your computer. The HDCP
technology checks compliance of each component in the path from the content on the Blu-ray disc all
the way to the display monitor, including but not limited to graphic cards and monitor adapters.
The HP 
400, 600 and 800 Workstations have been designed with this in mind; nearly all
configurations with currently available HP Professional Displays are compliant. Older HP xw4600 and
xw9400 Workstation configurations may not have fully compliant paths based on the installed graphics
card and display monitor; HP recommends confirming separately that you have a fully compliant system
if commercial content playback is a requirement for your use. HDCP compatibility of your graphics card
and monitor can be determined by checking the QuickSpecs at 
http://www.hp.com/go/productbulletin.
For the best HDCP performance, HP recommends that you install the latest updates:
1.Blu-ray player firmware
2.Playback application patches
3.Graphics firmware and drivers
Updates are located on the support web site for your specific product at 
http://www.hp.com/support/
workstations.
