There are three status indicators on the OIB2. The following table illustrates
the status and description for the status indicator states:
Replace Optical Interface Board 2
1. Note and mark the location and orientation of all the fiber optic cables.
Use the electrical drawing for reference.
2. Using your static strap, disconnect all of the connections. It may be
necessary to remove the 60 core cable connectors on the Optical
interface base and the ground connection for access to the standoffs.
3. Remove the OIB2 board from the OIBBS. There are four standoffs that
are secured in place on the OIB2. There is also the 28-pin connection
between the boards, and this connection must be handled carefully to
avoid bending the pins.
4. Install the new OIB2 on the OIBBS. Ensure all four screws for the
standoffs are replaced.
5. Reconnect all fiber optic connections and verify the locations.
6. Apply Low Voltage power and complete a Gating Test, System Test, and
Medium Voltage tests to ensure the new board functions properly.
7. Perform procedures as described in Verify Operation on page 23 .
Optical Interface Base Board
Safety This board provides the mechanical and electrical interconnections between
the OIB2s and the DPM as well as providing the required circuitry to
implement Safe Torque Off. It connects to either J11 or J12 on the DPM via a
60 conductor shielded ribbon cable. Attach the cable’s drain wire to the screw
terminal J8. The remaining connectors on the board complete the electrical
connection of the installed OIB2s to the DPM. Each OIBBS can support from
one to three OIB2s.
Status Indicator Status Description
D1 Red – On Run – The OIB2 has received an Enable signal. The drive control
software is in control of all gating.
D2 Yellow – On Ready –The OIB2 power supply is sufficient for proper operation.
D3 Green – On Power – The OIB2 has received a voltage signal greater than 2V.
D3 –On
D1 and D2 – Off Drive is powered and is in the safe state.
ATTENTION: Ensure that all medium voltage and control voltage power to
the drive is isolated and locked out.
