LUMO Housing Frame
Field-Serviceable Items
Opening and removing the front panel
The front panel of the LUMO frame is attached by swivel brackets. Two spring-loaded sliders
secure the panel in the closed position. To open the panel, pull the sliders toward the center of
the panel, and then pull the panel out until the support brackets allow it to move down below
the level of the power supplies. The supplies can then be removed.
To remove the status card, the door must be detached from the frame. Once the door is open,
push the flexible brackets apart until the door posts slip out of the holes in the brackets.
There are no electrical connections to the panel.
Reinstall the panel by slipping the door posts into the holes in the brackets, and then move the
door into position and snap it in place. The spring-loaded sliders will hold it in position.
Note that the door must be kept closed while the frame is in use, to ensure proper ventilation.
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.
