Power Connections
Three separate power connections are required on the iSBC 608/618 back-
plane (base unit):
J10, E29, and E30 (refer to figure 2-2).
The +5VDC
(E29) and GND (E30) connections are 10-24 machine screw terminals which
are attached directly to the backplane (see Figure 2-2).
Each terminal
location is clearly marked on the backplane.
Connections for the +12VDC, -12VDC, and -5VDC are made through receptacle
J10 on the backplane (see Figure 2-2).
Compatible connectors for this

MULTIBUS® AND AUXILIARY CONNECTORS
The iSBC 608/618 cardcage and backplane is equipped with eight Multibus
connectors.
These 86-pin connectors allow any iSBC board to be readily
installed into the cardcage (pin identification is provided in Figure
3-3).
Adjacent to each 86-pin Multibus connector on the backplane, space is
provided for a n auxiliary 60-pin connector.
Not all iSBC boards require
the auxiliary connector, therefore this connector is not supplied with
the cardcage.
Table 2-2 provides a partial list of vendors who supply
compatible auxiliary connectors for iSBC systems.
Auxiliary connectors
are secured to the backplane with two machine screws.
