System Cardcage for NCCNT WAN
The Model CC-5 Cardcage from Siemens Industry, Inc. (see Figure 1) has five card
slots and occupies two positions on the studs in the backbox or on the optional
CAB-MP Mounting Plate. The CC-5 is used for mounting all system circuit card
assemblies. It has two removable terminal block connectors at the top and one
removable terminal block connector at the bottom of each card slot. All field-wiring
connections are made directly to the top of the cardcage while internal power is
connected to the bottom of the cardcage. The two removable terminal block connec-
tors at the top of each slot are arranged in two rows. The lower row is labeled 1
through 8 and the upper row is labeled 9 through 16. These removable terminal
block connectors are used for connecting power limited external equipment. The
removable terminal block connector located at the bottom of each slot is labeled 17
through 24 and is used for connecting internal power.
CC-5 Card Cage
The CC-5 provides a central point for mounting circuit card assemblies. If a card
requires power, it is applied through the removable terminal block at the bottom of
the cardcage. All external devices for the card are connected to the card through the
two removable terminal blocks at the top of the cardcage. The circuit card assemblies
are connected to the HNET bus through the connectors on the cardcage.
The CC-5 is shipped with the card guides removed. The card guides are keyed to
assist in installation. They can be installed either before or after the cardcage is
installed in the enclosure. For ease of installation, the card guides have been de-
signed to be installed after the field wiring has been completed.
