4.1.1 Real-time clock battery
There is a battery located under the access door. This battery supplies power to the Real-
Time Clock (RTC) in the VL IPC when the system is not connected to a 24 V DC power
source. The battery has a typical life of 5 years and requires replacement occasionally.
To replace the battery
1. Open the access door at the rear of the IPC module.
2. The RTC battery is above the hard disk slot. Use a needle nose pliers to carefully pull
out the battery.
3. Be sure to replace the battery with the same type (CR2032 3V Lithium), oriented as
shown in Figure 4-4.

4.1.2 Hard disk drive
The hard drive installs in a tray that is easily removable. VL IPC systems without a hard drive
come with a blank tray. To install a new hard drive or replace the current hard drive, follow
these instructions:
1. Remove power from the unit.
2. Open the access door.
3. Turn the screw counterclockwise several turns. It is spring-loaded and, when it clears
the threads, it pops out.
4. Grasp the screw and swing the front lever out from the door.
