6 Remove/Replace Chassis Components
Before servicing the TVC-500 controller, please refer to Section 4 Service Guidelines.
6.1 Replacing Hot-Plug Components
It is not necessary to power down the controller to remove and replace hot-plug components. For all other
service tasks, power down the controller before proceeding. See Section 6.2 Powering Down the Controller
6.2 Powering Down the Controller
The front panel Power ON/Standby button does not completely power OFF System
power. Portions of the power supply and some internal circuitry remain active until AC power is
removed. If you are powering down for maintenance, you must also remove the power cord from the
power supply. Failure to remove the power cord may increase the risk of personal injury, electric shock,
or damage to the equipment.
If the power cord is removed for maintenance purposes, ensure that a wrist strap is
worn and grounded to the controller chassis and that the chassis is suitably grounded before working
inside the controller. Failure to do so may result in component damage due to Electro Static Discharge
(ESD).
1. Close all applications.
2. Shut down Windows 7 by selecting Start>Shutdown.
6.3 Main Chassis Side Access Panel
6.3.1 Removal
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal
system components to cool before touching them.
NOTICE: Do not operate the controller for long periods with the access panel open or removed.
Operating the controller in this manner results in improper airflow and improper cooling that
can lead to thermal damage.
1. Power down the TVC-500 controller. Refer to Section 6.2 Powering Down the Controller.
2. Remove locks that are present, such as cable lock or side access panel key lock.
3. Pull up on the handle (1 in Figure 6-1) and rotate the side access panel off the chassis (2 in Figure 6-1).
