System maintenance

To maintain your Business Communications Manager (BCM) system, you can replace damaged equipment, manage installed modules, and use BCM utilities to monitor performance and track statistics.

Prerequisites to system maintenance

• Ensure your BCM system is properly installed. For more information about

installing a BCM system, see Nortel Business Communications Manager 450 5.0 Installation — System (NN40170-303).

System maintenance tasks

This work flow shows you the sequence of tasks you perform to maintain your BCM system. To link to any tasks, click on System maintenance navigation

(page 10).

BCM450 equipment replacement

Replace BCM450 equipment and components when they are damaged.

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.

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

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.

--End--

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.
