5.3.9 +5 Vdc Regulator Trays (PN 70-29046-01 and 70-29046-02)

The XMI chassis contains two +5 Vdc regulator trays, a master unit (PN 70-
29046-01) and a booster unit (PN 70-29046-02). These two trays provide the
+5 Vdc power for the system. Their outputs are strapped together so that they
supply a single distribution rail in the system backplane. See Figure 5–25 for
location.
The +5 Vdc master and +5 Vdc booster regulator trays (see Figure 5–24) include
the following as field replaceable units (FRUs):
• One 5 Vdc master converter module (PN 20-34928-01) on the -01 board (E10)
• Five 5 Vdc booster converter modules (PN 20-34929-01) (two on the -01 board
and three on the -02 board)
