5.Troubleshooting 5.1 Common Problems

The following paragraphs describe procedures and Tablet Cart guidelines intended to provide assistance in finding and correcting potential malfunctions with the Tablet Cart.

•Make sure that the Tablet Cart is connected to a qualified 115-VAC power outlet and the cart’s power switch is set to ON.

•If the iPads loaded in the cart are to be synced, ensure that a computer running iTunes is connected to the cart’s USB port.

•The cart automatically detects the presence of a syncing computer connected to it and switches the iPads to their syncing mode. If no syncing computer is connected, the iPads are set to their charging mode.

NOTE: After syncing iPads for 4 hours (without disconnecting the syncing computer), the cart will automatically switch the iPads to the charging mode.

•Depending on the capacity of the Tablet Cart, it can include one or more controller board assemblies (located on the rear).

•Each controller board assembly is equipped with a blinking red status LED. For each controller assembly, observe the status LED to verify that the cart is set to the correct mode (sync or charging). The blinking rates are described in Table 5-1.

Table 5-1. Status LEDs.

Blink Rate (Blinks/Burst)	Description

2	Cart controller is in the iPad charging mode.

4	Cart controller is in the iPad syncing mode.

1	Cart is in the idle mode.*

*Under normal operation only the charging mode or syncing mode should be active. Idle is a default mode to indicate a possible controller malfunction (or failure to select one of the two other modes).

•Carts with more than one control assembly: If the first controller works as described, but subsequent controllers (to the right of the first controller) do not, insure that all the controllers are connected to each other with a CAT5 cable.

•The cart has the ability to detect a current overload present on each iPad connector. It will individually turn off the power to an iPad that is drawing an excessive amount of current. After an overload detection, the cart tries to reconnect power to the overload channel every 30 seconds.

To the user, an overload condition will be seen as the iPad not being charged or able to sync. If the condition remains for approximately five minutes after detection, remove the iPad and connect another iPad to the same channel to determine if the cart or iPad is at fault.

•The following message has been reported by iTunes when syncing an iPad:

Verify that the library being synced to is the same as the library previously used.
