When the enclosure powers up for the first time, it might take up to five minutes before all blades
are initialized and recognized by the Onboard Administrator. The time it takes to complete
initialization depends on the number of blades configured in the enclosure. For example, a full

the breaker panel rear cover, make sure that the power from the site into the breaker panel is off,
and switch all breakers in the front of the breaker panel off.
The breaker panels are installed from the top down, and the enclosures are installed from the
bottom up. In this configuration, the power cables are routed from the top breaker to the bottom
enclosure and from the bottom breaker to the top enclosure.
For connections up to 80A, use breakers 1-3. For connections up to 50A, use breakers 4-7. Each
module connecting to the breaker panel has a dedicated connection on Side A and Side B. Each
module connects to the same terminal number on each side. Verify that the breaker installed in the
front of the breaker is the correct amp size.
