MGC-50/100 Control Unit with Removable Hard Drive
As an option the Control Unit (CU) can be supplied with a removable Hard
Drive. The Hard Drive is pre-configured for either XPEK or pSOS Operating
Systems. This Control Unit does not include a floppy disk drive.
The following sections describe the steps required to install the removable
hard drive.
Removing the Control Unit from the MCU
Use the following procedure for both the MGC-100 and the MGC-50 to
replace the Control Unit:
1. Exit the MGC Manager application.
2. Switch OFF the main power switch on the rear panel and disconnect the
power cord from the power source.
3. Remove the cover at the rear of the MCU.
4. Disconnect the following cables from the Control Unit:
• The LAN (RJ-45) and Dongle (RS-232 Serial) cable connections
5. From the front of MCU, unscrew the four screws that secure the Control
Unit to the chassis.
• MGC Manager versions 6.11 and 7.0.2 also can support the removable
Hard drive.
• It is possible to configure several removable Hard drives for a single MCU.
Sharing Hard Drives between two different MCU’s is not possible due to the
different cards, network services and reservations. However, if you need to
move a drive to another MCU contact Polycom support.
The Control Unit is not hot swappable.
A modem may be connected to the RS-232 port on the front panel of the
Control Unit. If present, disconnect.
