In sta l li ng t he DT RU Modu le
1. Unpack the DTRU Module from its antistatic conductive bag in the
pack ing box.
2. Locate the CON1 and CON2 connectors on the DTRU module.
3. Locate the CONN1 and CONN2 conne ctors on the SLIB (outline d).
4. Pos ition the D TRU module s o that the CON 2 and C ON1 conne ctors
m atch up with the CON N1 and CON N2 connectors on the S LIB
respectively.
5. Pus h the DT RU module onto th ese conne ctors mak ing sure it is
seated properly.
Refer toFig u re 2- 23.This completes the installation procedure for the
DTRU Modul e.

1. Unpack the MSGU Module from its antistatic conduc tive bag in the
pack ing box.
2 . Locat e t he CO NN1 and CO NN2 conne ctor s on t he MS GU m odule .
3. Locate the CONN3, a nd CONN4 conne ctors on the SLIB ( outline d).
4 . Pos it ion t he MS GU mod ule so th at th e CO NN1 a nd CO NN2
connectors match up with th e CONN3 an d CONN4 connectors on the
SLIB respectively.
5. Pus h the MSGU module on to the se connec tors m aking s ure it is
