NOTE:
• If you were unable to check the Addition Completed window because
you closed the dialog while adding the expansion unit, wait for about
three minutes and display the Trays window again in Navigator 2.
Follow steps 2 - 4 in the Trays window.
• If the chassis being added is displayed, the addition is completed.
If it is not displayed, remove the cables connected at the time of the
addition and add the chassis again.
• If you connect the power cables to the Power Unit of the added
expansion unit, the Alarm LED on the ENC Unit turns ON. This is
normal and is not an error. The LED will turn OFF when the addition is
complete.

unit is being added, the window closes but the Locate (LOC) LED stays
on. To turn off the Locate LED:
a. In the Trays window, click Refresh Information to update the
window.
b. Select the tray in which the position column is displayed as ON, and
click Disable Locate. The Locate LED should turn off.
