InfraStruXure Central does not read some sensor names if changes are made after initial discovery.
InfraStruXure Central 4.x
During testing, a device with a system name that had an escape character in it was polled by InfraStruXure Central's Device Scanners. It was noticed that this caused adverse effects to the operation of ISX Central. APC recommends that no strange characters be used in any editable fields when configuring clients that are to be queried by the ISX Central's Device Scanners.
This is resolved in version 5
