BCM450 internal component
replacement
You can replace components in the BCM450 main unit if they are defective or
damaged.
Prerequisites to BCM450 internal component replacement
• Ensure the BCM450 system is shut down. For more information, see
Shutting down the system for maintenance (page 36).
• Disconnect the main unit from the power outlet.
• Remove the BCM450 main unit from the rack, wall, or desktop and set it
on a flat, clean, static-free surface.
• Ensure you have the following tools:
— Phillips screwdriver #2, with a 3.5-inch blade
— 3/16-inch slot screwdriver
— Antistatic wrist grounding strap
CAUTION
Risk of damage to equipment
You must wear an antistatic grounding strap at all times when
handling electronic components. Failure to do so can result in
damage to the equipment.
CAUTION
Risk of information loss and damage to equipment
Do not use an electric or magnetized screwdriver near the hard disk.
You can lose the information stored on the disk. Shock can damage
the hard disk. Do not drop or hit the hard disk.

Replacing a media bay module
This section describes how to replace a media bay module (MBM) installed in
your BCM450 main unit or expansion cabinet if it is defective or damaged.
This section describes replacing an MBM with the same type of MBM. If you
want to replace an MBM with a different type of MBM, you must treat it as a
new installation. Ensure the new MBM does not overrun any lines already
assigned to other MBMs.
Prerequisites
• Turn off the BCM450 system. For more information, see “Shutting down
the system for maintenance (page 36)”.
• Ensure the BCM450 main unit is disconnected from the AC power source.
Procedure steps
Step Action
1Remove any cabling from the MBM faceplate.
2Grasp the right edge of the MBM ejector lever with your thumb, index and
middle fingers.
3Pull outward to partially eject the MBM. Pull further on the lever to eject the
MBM from the bay.
4Grasp the top and bottom edges of the MBM, and remove it from the BCM
unit. Place the MBM in a clean, safe, and static-free area.
5Set the DIP switches on the new MBM to match the settings of the old MBM.
6Install the new MBM in the main unit or expansion cabinet. For more
information about installing an MBM, see Nortel Business Communications
Manager 450 Installation — System.
7Return the BCM450 system to normal operation.

Removing the power supply
Remove the defective power supply from your BCM450 main unit or BCM450
expansion cabinet before installing the new power supply.
Procedure steps
Step Action
1Shut down the BCM450 system. For more information, see Shutting down
the system for maintenance (page 36).
2Disconnect all cables from the front of the base function tray.
3Disconnect the main unit and the expansion cabinet (if applicable) from the
AC power connection.
4Attach one end of the grounding strap to your wrist and the other end to a
grounded metal surface.
5Loosen the screws securing the power supply module (located at the back
of the unit, on the right).
6Pull handle located on the power supply module outward to remove the
power supply module from the unit.
--End--
WARNING
Risk of leakage currents
You must disconnect the telephony and data networking cables from
the system before disconnecting the power cord from a grounded
outlet.
CAUTION
Risk of equipment damage
Protect the hardware components against damage from elec-
trostatic discharge. Always wear a grounded wrist strap before
you handle components. Always place the components in a
static-free container.

Connecting the new power supply
After you remove the defective power supply, connect the new power supply
to your BCM450 main unit or BCM450 expansion cabinets.
Prerequisites
• Ensure that the new power supply is an auto adjust power supply.
Procedure steps
Step Action
1Firmly slide the power supply module directly into the power supply bay.
2Tighten the screws to secure the power supply module.
--End--
Removing the hard disk
Remove the damaged hard disk before installing the new hard disk.
Procedure steps
Step Action
1In Business Element Manager, go to Administration >System
Metrics>Disk Mirroring. Determine whether it is HDD-1 in the first (left)
hard disk slot or HDD-2 in the second (right) slot that has failed.
The Status section will list one of the drives as Failed and not Passed. If the
system has been rebooted since the failure has occurred, depending on the
type of hard disk failure, a second drive may not be listed in this section. In
that case, the drive that is installed but does not have a lit HDD LED and is
not listed in the Status section will be the failed disk to be replaced.
2Turn off the BCM450 system and disconnect it from the AC power source.
For more information, see Shutting down the system for maintenance
(page 36).
CAUTION
Risk of damage to equipment
Do not use an electric or magnetized screwdriver near the hard disk.
You can lose the information stored on the disk. Shock can damage
the hard disk. Do not drop or hit the hard disk.

3Attach one end of a grounding strap to your wrist and the other end to a
grounded metal surface.
4On the bottom left of the base function tray, loosen the thumb screw and
remove the hard disk bay faceplate.
5Using your thumb and forefinger, pull hard disk bracket forward, out of the
main unit.

6Lift the failed hard disk and hard disk bracket from the main unit, and place
them on a flat, clean, static-free surface.
7Remove the four screws that secure the hard disk to the hard disk bracket.
8Lift the hard disk from the hard disk bracket, and set it on a flat, clean, static-
free surface.
--End--
Installing the hard disk
Install the new hard disk into the BCM450 main unit.
Prerequisites
• Remove the hard disk. For more information about removing the hard disk,
see “Removing the hard disk (page 17).”

Procedure steps
Step Action
1Attach one end of a grounding strap to your wrist and the other end to a
grounded metal surface.
2Place the new hard disk in the hard disk bracket.
3Use the four hard disk bracket screws to secure the hard disk to the bracket.
4Push the hard disk and bracket forward into the hard disk bay (the left most
slot).
5Press down lightly on the top of the hard disk to ensure that the hard disk
bracket is seated properly.
6Replace the hard disk bay panel, and tighten the thumb screw.
7Restart the BCM450.
The HDD LED (or both HDD LEDs if a redundant hard disk is present)
should be green indicating that the replacement disk was installed correctly.
8In Business Element Manager, go to Administration >System
Metrics>Disk Mirroring.
9In the Operation mode field, under the Settings sub-panel, select Mirror
Mode to enable disk mirroring to maintain a redundant hard disk if you have
two hard disks installed. Otherwise, ensure that HDD-1 is selected.
--End--
Installing the CEC
You can install the optional compact expansion card (CEC) to increase the
capacity of the BCM450 system.
Prerequisites
• Turn off the BCM450 system. For more information, see “Shutting down
the system for maintenance (page 36)”.
• Ensure the BCM450 main unit is disconnected from the AC power source.
CAUTION
Risk of equipment damage
Use only the screws that you removed from the hard disk. Using
other screws can damage the hard disk.

4Screw the four metal standoffs (included) into the main board of the base
function tray.
5Slide the CEC into position from the back of the base function tray, so that
the CEC protrudes slightly from the front faceplate of the base function tray.
6Align the connectors on the card and on the main board of the base function
tray and push down. Ensure that the card is connected securely to the main
board.
7Use the four supplied screws to fasten the card to the standoffs.
8Reinstall the base function tray and power on the BCM450 system.
CAUTION
Risk of damage to equipment
You must wear an antistatic grounding strap at all times when
handling electronic components. Failure to do so can result in
damage to the equipment.
