UPS Model Name Prefix | UPS Serial Port Connector Type | System Configuration with AP9624 Interface Expander 2 in Confirmed Mode with DIP Switch 4 Down | Valid or Invalid? | Reason why Configuration is Valid or Invalid |
SU, SUA, SUVT/G3500, SURT, SURTA, SRC, Symmetra LX | DB-9 |
|
Invalid | There is no client connected to the UPS "smart" serial port. The Interface Expander 2 would wait "forever" for something that will never happen. |
SU, SUA, SUVT/G3500, SURT, SURTA, SRC, Symmetra LX | DB-9 |
|
Valid | Since there is a client on the UPS "smart" port, the Interface Expander 2 will wait for the smart client to signal a shutdown and complete it's full turn off/reboot process. The Interface Expander 2 can "talk" to the UPS communication port with this UPS architecture. |
SMT, SMX, SRT, SRC | RJ-45 |
|
Invalid | There is no way on these specific UPS types for the Interface Expander 2 to know whether or not there is a "smart" client connected to the UPS port due to the UPS architecture. The DIP Switch signifying if smart client exists must be done by the user. The user needs to put DIP Switch #4 in the "up" position and make sure their maximum required delay is set accordingly to allow time for all "connected clients" to shutdown, as to not initiate a pre-mature shutdown before Interface Expander 2 clients have had a chance to shutdown. |
SMT, SMX, SRT, SRC | RJ-45 |
|
Invalid | This configuration is invalid as the "upstream" port of these UPS models is not connected internally to the Interface Expander 2 but instead has a direct UPS connection. Therefore, from the Interface Expander 2's perspective, it should not have an upstream client awaiting confirmation because it will not be able to talk to that UPS port and receive a confirmation. |
SURTD, SRC2KUXI, SRC3KUXI, SRC3KUXIX709 | RJ-45 |
|
Invalid | These UPS types only support simple signaling on their RJ-45 UPS communication port. Since the client is not "smart", the DIP switch needs to be set manually by the user too in order to tell the Interface Expander 2 whether there is a client connected or not on the UPS port. |
SURTD, SRC2KUXI, SRC3KUXI, SRC3KUXIX709 | RJ-45 |
|
Valid | These UPS types only support simple signaling on their RJ-45 UPS communication port. Since the client is not "smart", the DIP switch needs to be set manually by the user too in order to tell the Interface Expander 2 whether there is a client connected or not on the UPS port. In order to do that, DIP switch #4 should be down. |
