BCM50 Installation and Maintenance Guide
Installing the new expansion unit
Use one of the following procedures to install the new expansion unit:
•
“Installing the BCM50 unit in an equipment rack” on page 80
•
“Installing the BCM50 unit on the wall” on page 84
•
“Installing the BCM50 unit on a desktop or shelf” on page 89
After installing the new expansion unit proceed to the procedure
“To connect the cables”
.
To connect the cables
1
Insert the power supply retention clip into the new expansion unit.
2
Rotate the power supply retention clip so that the power supply jack is clear.
3
Connect the power supply cord to the expansion unit.
4
Rotate the power supply retention clip to lock the power supply cord in place.
5
Connect the expansion cable to the expansion port on the front of the expansion unit.
6
Connect the LAN cable to the LAN port on the front of the expansion unit (if applicable).
7
Connect all of the telephone line and extension cables to the MBM inserted in the expansion
unit. To ensure the same line and extension numbering, make sure you connect the cables to
the ports from which the were removed.
8
Use Element Manager to enable the MBM. Refer to the BCM50 Administration Guide
(N0016868) for more information on enabling an MBM.
To return the system to operation
1
Check the Power and Status LEDs on the main unit. Both LEDs should be solid green. If either
LED is not solid green, there is a problem with the main unit. Refer to
“System status LEDs”
on page 59
for a detailed description of the LED states.
2
If this system has an expansion unit, check the Power and Status LEDs on the MBM in the
expansion unit. Both LEDs should be solid green. If either LED is not solid green, there is a
problem with the MBM or the expansion unit. Refer to
“Media bay module LEDs (expansion
units only)” on page 64
for a detailed description of the LED states.
3
If this system has a second expansion unit, check the Power and Status LEDs on the second
MBM.
4
Use Element Manager to restore the programming. For information about restoring system
programming, refer to the BCM50 Administration Guide (N0016868).
Warning:
Leakage currents
You must connect the power cord to a grounded outlet before connecting the
telephony and data networking cables to the system.
