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.

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
1 Remove any cabling from the MBM faceplate.
BCM450 internal component replacement 15
2 Grasp the right edge of the MBM ejector lever with your thumb, index and
middle fingers.
3 Pull outward to partially eject the MBM. Pull further on the lever to eject the
MBM from the bay.
4 Grasp 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.
5 Set the DIP switches on the new MBM to match the settings of the old MBM.
6 Install 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.
7 Return 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.
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 electrostatic discharge. Always wear a grounded wrist strap before
you handle components. Always place the components in a
static-free container.
Procedure steps
Step Action
1 Shut down the BCM450 system. For more information, see Shutting down
the system for maintenance (page 36).
2 Disconnect all cables from the front of the base function tray.
3 Disconnect the main unit and the expansion cabinet (if applicable) from the
AC power connection.
4 Attach one end of the grounding strap to your wrist and the other end to a
grounded metal surface.
5 Loosen the screws securing the power supply module (located at the back
of the unit, on the right).
6 Pull handle located on the power supply module outward to remove the
power supply module from the unit.

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
1 Firmly slide the power supply module directly into the power supply bay.
2 Tighten the screws to secure the power supply module.
Removing the hard disk
Remove the damaged hard disk before installing the new hard disk.

Procedure steps
Step Action
1 In 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.
2 Turn 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.

Redundant power supply installation
This chapter describes how to install the optional redundant power supply and
cooling fan into the BCM450 main unit.
Each power supply has its own AC power connector, an Audible Fail Alarm
shutoff button, and a power switch.
Attention: Both power switches must be turned on at all times. When
shutting down the BCM system, disconnect the power cords from the AC
power source; do not turn the power switches off.
Prerequisites for redundant power supply installation
• You require a redundant power supply upgrade kit (NTC03180TXE6).

Procedure steps
Step Action
1 Attach one end of a grounding strap to your wrist and the other end to a
grounded metal surface.
2 Remove the fan access panel screws at the top and bottom of the panel.
Place the screws in a safe location.
3 Tip the top of the fan access panel toward you.
4 Grasp the fan access panel with both hands, and then lift it away from the
main unit. Do not stretch the fan cables.
5 Disconnect the CIF card fan cables.
6 Remove the snap rivets that hold the fan to the fan access panel. The snap
rivet has two parts: a center pin and a collar. Gently separate the plastic rivet
pin with your fingernail from the center of the rivet collar. Remove the rivet
pin and collar from the fan access panel. Place the rivet pin and collar in a
safe location.
7 Lift the fan away from the fan access panel. Put the old fan access panel in
a safe location.
8 Place one of the fans on the new fan access panel, over one of the grills.
9 Ensure you orient the fan cable to the bottom of the fan and that the fan label
is closest to the grill on the panel.
Attention: Ensure the label of the new fan faces the back of the BCM450 unit. Air
must flow out of the unit as indicated by the embossed arrows on the fan.
10 Align the fan chassis mounting holes with the holes in the fan access panel.
11 Hold the fan in place against the fan access panel, and then push the rivet
collar through the fan access panel and fan chassis mounting holes.
12 Insert the rivet pin into the rivet collar.
13 Repeat steps 8 through 12 for the second fan.

Returning the system to operation
Return the BCM system to operation to restart telephony services after you
complete your maintenance operations.
Prerequisites
• For more information about installing the system, see Nortel Business
Communications Manager 450 Installation — System.
WARNING
Risk of service loss
When you restart the system, all digital telephony, IP client voice
mail, and Voice over IP (VoIP) ports are not available until the system
services restart.
WARNING
Risk of leakage currents
You must reconnect the power cord to a grounded outlet before
reconnecting the telephony and data networking cables to the
system.
Procedure steps
Step Action
1 If you removed the BCM450 main unit from the rack or wall, replace it.
2 Ensure your BCM450 power supply is connected to your BCM450 system
and to an AC wall outlet or a UPS.
3 Ensure the telephony cables are connected to the BCM main unit and BCM
expansion cabinets.
