Cause

The procedure for installing/removing a SmartSlot accessory card typically depends on the connector of the SmartSlot accessory. In most situations, SmartSlot cards can be hot swapped as long as the accessory pins are not all of the same size on either the top and/or bottom of the SmartSlot connector. See below.

Generic reference showing SmartSlot connector with 24V and Ground connectors longer than communication connectors:




Underside of AP9630 Network Management Card 2



The two longer pins are the 24V and ground connections. If your SmartSlot accessory looks similar or has two or more pins that are longer than the others, this identifies the SmartSlot accessory as hot swappable.


Reminder: Depending on the accessory, you'll need to look on either the underside or top side of the SmartSlot connector.



Resolution


Verify for your specific accessory whether the pin orientation verifies the SmartSlot accessory is hot swappable. If it is, you can remove and install the SmartSlot card while the UPS unit is in operation.

Accessories manufactured from 1999-present day should be hot swappable. You can verify manufacture date by looking at the accessory's serial number. The first six characters should be referenced. For example, JA0632 - the 06 indicates the build year and the following two digits are the build week, 32. So, this example shows the accessory was manufactured in the 32nd week of the year 2006.

If you're unable to verify the manufacture date, pin orientation, or you suspect there is a problem either with the accessory or SmartSlot for some reason and rather exercise further caution for a particular reason, follow the procedure(s) below to remove/install an accessory depending on your UPS type. This is not required by design though.


Smart-UPS (SU, SUA, SURT models 2200VA and below) - The unit can be completely powered down, commonly referred to as a "braindead."

The full power down procedure is below:

1. Turn off the equipment that is connected to the UPS
2. Disconnect the UPS from its AC (input power) source
3. Press the off button to turn the UPS off. Release.
4. Press and hold the off button for approximately five seconds to turn off the DC (battery) power. You may hear the unit click and flash its front LCD.
5. It is now safe to remove or install a SmartSlot accessory card and then plug the UPS back in and turn it on.

Next Generation Smart-UPS (SMX/SMT) - The unit can be completely powered down, commonly referred to as a "braindead."

The full power down procedure is below:

1. Turn off the equipment that is connected to the UPS
2. Disconnect the UPS from its AC (input power) source
3. Turn off the output on the UPS either via the LCD or using the Power button (refer to your user's guide.)
4. Remove the internal and external battery connections from the UPS for 20 seconds.
5. It is now safe to remove or install a SmartSlot accessory card, reinstall the battery connections, and then plug the UPS back in and turn it on.

Smart-UPS RT (SURT, SRT models 3000VA and above), Matrix-UPS - The unit can be put into bypass mode.

The bypass procedure is below:

1. On the Smart-UPS RT, there is a small bypass flip switch on the back of the unit. (3000VA and higher, else refer to Smart-UPS SUA instructions)
2. On the Matrix, you must loosen the black thumbscrew on the back side of the unit.
