Remove the media services card (MSC)
Use this procedure to remove the media services card from the base function tray.
1 Ensure you have a current data backup of your system.
1 If you still have access to the Unified Manager, shut down the system using the Shutdown
command. For details refer to “Shut down the system software” on page 145. Otherwise, skip
to step 2.
2 Set up the server for maintenance, as described in “Shut down the system hardware” on page
146.
3 Disconnect the Business Communications Manager from the AC power outlet.
4 Disconnect any cables from the front of the base function tray.
5 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
6 Partially remove the base function tray from the platform base chassis (See “Remove the base
function tray” on page 150). Do not exert force on the DS30 cables and connectors.
7 Disconnect the DS30 cables.
8 Remove the base function tray completely from the platform base chassis. Ensure you do not
pinch or damage any cables (see “Remove the base function tray” on page 150). Place the base
function tray on a flat, clean and static-free surface. Continue to the next step of this procedure
when complete.
9 Remove the base function tray bezel. See “Remove the base function tray bezel” on page 153.
Continue to the next step of this procedure when complete.
10 At the front of the base function tray, loosen and remove the PCI cover plate screw (use a #2
Phillips screwdriver). Figure 146 shows an interior view of the base function tray. Place the
screw in a safe location.
11 Remove the PCI cover plate from the base function tray chassis. Place the PCI cover plate in a
safe location.
12 Remove the two chassis mounting screws that secure the MSC to the base function tray
chassis extension (at the rear of the MSC) - see Figure 151. Place the screws in a safe location.
Warning: Protect the hardware components against damage from electro-static
discharge. Always wear a ground wrist strap before you handle components. Always place
the components in static-free container.
Note: If you purchased optional Business Communications Manager applications that
require keycode activation, regenerate the keycodes after you re-install the replacement
MSC. For further information, see “Regenerating keycodes after system replacement” on
page 142 and “Install the media services card (MSC)” on page 226.
