Replacing Other I/O Packs; Eswx To Eswx Switch Replacement; To Replace An Eswx Switch - GE Mark VIeS System Manual

12.2.1.3 Replacing Other I/O Packs

Replacement of the terminal board requires full reconfiguration of the changed component using the ToolboxST application.
For this reason, it is generally preferable to replace only the I/O pack unless the terminal board is known to be the point of
failure.
➢ ➢ To replace an I/O pack
1. Verify that the replacement I/O pack is compatible with one being replaced.
2. If replacing a BPPB-based I/O pack with a functionally compatible BPPC-based I/O pack:
The site's ControlST software must be minimum V04.04. Verify the version and upgrade the site if needed.
a.
b. If needed, download the BPPC I/O Upgrade package from the GE Intelligent Platforms Support website or check the
version of ControlST software suite at site to verify that it contains the required I/O pack firmware version.
c. If needed, install the required I/O pack firmware to the HMI.
d. From the ToolboxST application, perform an upgrade of the firmware. This modifies the .tcw system file on the
HMI. Do this prior to physically replacing the I/O pack hardware. Refer to the ToolboxST User Guide for Mark VIeS
Functional Safety Systems (GEH-6862) for help with this upgrade feature.
3. Lockout tagout the field equipment and isolate the power source.
4. Remove the power to the I/O pack. Remove the power plug located in the connector on the side of the I/O pack.
5. Unplug the Ethernet cables and mark the positions of the removed cables.
Loosen the two mounting nuts on the I/O pack threaded shafts.
6.
7. Unplug the I/O pack.
8. Plug in the replacement I/O pack. Make sure the I/O pack connector is fully seated on all sides, then properly tighten
mounting nuts.
9. Plug the Ethernet and power cables back into the I/O pack and re-energize the equipment.
10. If replacing a BPPB-based I/O pack with a functionally compatible BPPC-based I/O pack: from the ToolboxST
application, change the hardware form, build, and download the application code to the controller.

12.2.1.4 ESWx to ESWx Switch Replacement

➢ ➢ To replace an ESWx switch
Remove the power connector(s) from the ESWx, located on the right side of the switch.
1.
2. Remove the Cat 5e cable connections, recording the port where the cables were installed.
3. Remove the fiber-optic cable connections (if present), recording the port where the cables were installed.
4. Remove the switch module from the panel.
If replacing a DIN-rail mounted ESWx, transfer the DIN-rail mounting clip from the failed unit to the replacement unit.
5.
6. If replacing a standard panel mounted ESWx, transfer the mounting bracket from the failed unit to the replacement unit.
7. Mount the replacement switch module into the panel.
8. Reconnect the Cat 5e cables and fiber-optic cables.
Reconnect the power connections.
