Card Slots. The rear of the cards requiring a transition module (T1, E1, DS1, CPU) is used for network connection. The quantity will vary depending upon the number of cards you have inserted.

Power Plug. Provides wire connections to the -42 to -60 VDC power from the DC feed(s) to the power receptacles. Both may be used, but only one is required (one must have the power connected to its power inlet connector).

Power Receptacle. Power inlet receives DC power from the power plug.

Circuit Breaker. There is one circuit breaker for each power connection; an arrow from each one indi- cates which breaker controls which power receptacle connection. The top circuit breaker controls the left power receptacle; the bottom circuit breaker controls the right power receptacle. When you push the rocker to ON, the breaker will be closed (a red indicator shows the user that the contacts are closed). When you push the rocker to OFF, the contacts will open. Both circuit breakers must always be open, even if only one power source is connected to the chassis, to ensure all power is disconnected from the power supplies.

Earth Ground Terminal An earth ground terminal is provided to connect to a supplemental earth ground.

ESD Socket. A ground connection is provided for ESD protection.
