TP Dock 1 - FRU Removals and Replacements

Applicable to: World-Wide

FRU Removals and Replacements:
This section contains information on removals and replacements, and locations.
The arrows in the removals and replacements show the direction of movement to remove a field replaceable unit (FRU), or to turn a screw to release the FRU. The arrows are marked in numeric order to show the correct sequence of removal. When other FRUs must be removed before removing the failing FRU, they are listed at the top of the page. Go to the removal procedure for each FRU listed, remove the FRU, and then continue with the removal of the failing FRU.

To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See 'Locations— for internal cable connections and arrangement information.

CAUTION:
Before removing any FRU, power-off the Dock I, remove the computer, unplug all power cords from electrical outlets, then disconnect any interconnecting cables.

CAUTION:
In the U.K., by law, the telephone cable must be connected after or disconnected before the power cord.

Warning:
The main board, adapters, and circuit boards on the drives are sensitive to, and can be damaged by, electrostatic discharge. Establish personal grounding by touching a ground point with one hand before touching these units.

Note:
An electrostatic discharge (ESD) strap must be used to establish personal grounding.

Important:
See the - 'Screw Size Chart' - to match the letters to the correct screw type and size before replacing each screw.
