Changing the Power Supply
The LUMO frame supports dual redundant hot-swappable power supplies. The basic configura-
tion includes a single supply, plus an empty slot for the optional redundant power supply.
Installing a second power supply module and applying power to it automatically engages the
redundant supply mode. Each power supply has its own power socket on the rear panel, and
should be connected to the AC supply using the supplied power cord or other approved cord.
• A single supply can be installed in either of the two slots
To install or change a power supply module:
1 Open the front panel of the frame
2 Remove the power supply module by pulling on the handle on its front panel and sliding it
out of the frame
3 Slide the new power supply module into the slot, and push it gently into position to seat the
connectors. There is no guiding slot - the supply base sits on the floor of the frame.
4 Close the front panel of the LUMO frame. The panel secures the power supplies in place.
Replacing or Upgrading the Controller Card or Status Card
The Controller or Status card is located between the power supply slots at the center of the
frame. To replace the card, proceed as follows:
1 Open the center front door, remove the door and push the door mounting brackets back
into the frame
2 Hook your finger over the plastic diffuser mounted at the front of the card, and pull out gen-
tly until the card is released from the rear connector; then slide the card out of the frame.
3 Slide the new card into the controller slot, and push gently on the card edge to engage the
rear connectors.
