Communication or power problems

Problem	Cause	Solution
The Labware MiniHub does not turn on.	The electrical requirements are not met.	Make sure the electrical requirements are met. See the G5584A Labware MiniHub Safety and Installation Guide.
The Labware MiniHub does not turn on.	The power supply on/off switch is set to the off (o) position, or the Labware MiniHub is not connected to the power supply or the power source.	Verify that the Labware MiniHub power supply on/off switch is set to on (I) and that the power supply is connected properly. See Turning on and off the Labware MiniHub.
The power light is on, but the Labware MiniHub does not rotate.	The Labware MiniHub is not initialized.	In the Labware MiniHub Diagnostics Profiles tab, make sure the correct profile is initialized, and that the profile specifies the correct device ID. For details, see Creating Labware MiniHub profiles.
	The Labware MiniHub is not connected to the controlling computer.	Make sure the Ethernet cable and connections to the computer are secure and in good condition.
	Either an error occurred or the motor is disabled. An obstruction may be preventing the Labware MiniHub from rotating.	Check the motor status light on the base. See Status lights. • If the motor status light is red: Remove any obstacles in the path of the Labware MiniHub. Re-enable the motor using Labware MiniHub Diagnostics. See Enabling and disabling the motor. • If the motor status light is green, see Checking the fault indicator.

Homing and other problems

Problem	Cause	Solution
The Labware MiniHub does not home.	The home position is set incorrectly.	Reset the home position and try again. See Setting the home position.
	The encoder might be dirty or damaged.	Contact Agilent Automation Solutions Technical Support.
	A communication error might have occurred.	Make sure the Ethernet cable and connections to the computer are secure and in good condition.
The robot does not place or pick labware correctly at the Labware MiniHub.	The robot teachpoints might be set incorrectly, the Labware MiniHub has moved after the teachpoints were set, or the shelves are bent.	Check and reset the robot teachpoints. See Setting robot teachpoints. Check for and replace bent shelves.
The Labware MiniHub has stopped and the motor status light on the base is red.	The motor is disabled, possibly because an obstacle prevented the Labware MiniHub from rotating.	Remove the obstacle, click Retry, and resume operation. Reinitialize the Labware MiniHub. If the problem persists, power cycle the device.
