Capacity expansion card installation
This chapter describes how to install the optional capacity expansion card
(CEC) into the BCM450 main unit. The CEC provides increased media
processing capacity to support up to 300 stations and 130 trunks, as well as
the associated increases in application capacity.
Installing the CEC
Use the following procedure to install the CEC in the main unit.
Prerequisites
• Power down the BCM450 system.
• You will require a Phillips head screwdriver.
• Ensure the BCM450 main unit is disconnected from the AC power source.
Step Action
1 Power down the BCM 450 system and remove the base function tray.
2 Attach one end of a grounding strap to your wrist and the other end to a
grounded metal surface.
3 Remove the plastic cap on the CEC slot on the front of the base function tray
by applying pressure to the bottom of the faceplate from the inside of the
Base Function tray. Once the bottom has come loose, remove the faceplate
from the front.
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.
