Installing a Rackmount DPE
13. To expand this DPE, cable its LCC EXP connector to the next
corresponding DAE’s PRI (primary) connector, as shown below.

14. If the DPE has another SP, LCC, and DAE, connect the DPE’s
other LCC and the DAE’s other LCC as above.
15. To connect additional DAEs, attach a copper cable between the
DAE’s LCC EXP connector and the next DAE’s PRI (primary)
connector (detailed in the DAE Installation Manual). If this DAE
and the next DAE have a second LCC, repeat this step for the
second LCC.
16. Make sure all the slots in the DPE and in each DAE contain either
CRUs or filler modules. At least two disk modules are required in
the DPE. We recommend inserting them in slots 0 and 1.
17. In the cabinet, set the main circuit breaker switches to the on
position.
The DPE and any DAEs in the cabinet will power up.
