For the 1260-101 follow the instructions below:
1. Remove the eight screws from the access panel. Remove the access panel.
2. Remove the three screws on the Mezzanine board. Disconnect the Fail LED cable from the
connector on the Mezzanine board. Next, remove the Mezzanine board by pulling it straight
out of the carrier.
3. Carefully remove the Local Bus Jumper Assembly (P/N 405951) and Bus Grant Jumper
Assembly (P/N 405951-003) from the Mezzanine board, taking care not to bend the
connector pins. Store these in a safe place in case the Option-01T needs to be relocated
later.
4. Position the Option-01T over the Mezzanine board, so that connectors P3 and P4 on the
Option-01T align with Mezzanine connectors J1 and J2, respectively. Press the Option-01T
and Mezzanine board together so that the connectors mate fully. Secure the Option 01T to
the mezzanine board using the three screws included.
5. Re-install the Mezzanine board into the carrier. Connect the Fail LED cable to the three-pin
plug on the Option-01T module. Polarity does not matter; it may be connected in either
direction.
6. Re-install the access panel and secure with screws.
7. The user may want to mark the 1260-101 to indicate that the 01T is installed.
