Answer: Please following the following steps in resetting the SYXRCC on the Symmetra Extended Run Frame:

1. Disconnect the communication cable(s) in the SYXRCC located in the back of the Symmetra Extended Run Battery Frame and wait for the green status light to go off.
2. Disconnect the communication cable(s) from the communications card by unscrewing the top right hand thumbscrew on the SYXRCC so that the micro-latch that is being held by that thumbscrew is unseated.
3. Reseat the micro-latch on the SYXRCC and screw in the thumbscrew back into the top right-hand corner of the SYXRCC.
4. Reconnect the communication cable(s) in the back of the SYXRCC and acknowledge the return of the green status light within 60 seconds the UPS will rerecognize the additional batteries and adjust the runtime value accordingly to include the batteries located in the Extended Run Frame.

Answer: Only SmartSlot accessories with revision K or later can be integrated with the Symmetra. When placing multiple SmartSlot accessories in the Symmetra expansion slots, great care must be taken so the correct ordering of the accessories is observed. A SmartSlot device with higher priority must be placed in the SmartSlot labeled with the higher number.

The following graphic is an example of how to install multiple SmartSlot devices in the Symmetra Power Array. Please note the numbering shown in the figure. The PowerNet SNMP Adapter is installed in slot #4, Call-UPS II in #3, no device in #2, and Measure-UPS in #1.

Answer: There is only one serial port on each Smart-UPS model UPS that operates in "Smart" signaling mode. All Smart-UPS models 700 and higher also have a Smart Slot available for optional accessories. For Smart-UPS models 700 and higher, there are two options for shutting down multiple servers when a UPS goes to battery.

The first option is to purchase an APC Interface Expander - part number AP9607 (provides additional 2 ports) or AP9207 (provides additional 7 ports). You may also daisy chain up to four of the AP9207s, allowing 32 total servers to be monitored off of one UPS. This solution requires the purchase of additional APC basic signaling serial cables - part number 940-0020.

This solution is the communication across a physical serial connection between the UPS and attached servers for use with our PowerChute Business Edition (PCBE) software. To check which operating systems are compatible with PCBE, please follow this link: http://www.apcc.com/products/family/index.cfm? id=125&web_displayed=.f If you are using a version of Unix that is not supported by PCBE, but is supported by PowerChute Plus, you would need to purchase the AP9823 simple signaling cable for Unix.

If you prefer not to have additional serial cables cluttering your server room, you could opt for the network shutdown solution. This option requires the purchase of APC part #AP9617, AP9618 or AP9619 - the Network Management Card. By installing the Network Management Card (NMC) into the UPS and configuring an IP address for the card, you make the UPS a node on your network. You will then download the free PowerChute Network Shutdown (PCNS) software from www.apc.com/tools/download and install it on any computer you wish to shutdown gracefully during a power event. Operating system compatibility with PCNS is also listed on our software downloads page.

When the UPS goes to battery, it broadcasts a message to any computer with PCNS installed. Options and parameters are easily configured through the web interface. You can remotely configure the servers for shutdown and remotely monitor the UPS with the NMC option.
