not substitute other covers as they may not meet the re-

quired speciﬁcations.

Operating the system without the slot covers has the

following consequences:

• The system may overheat due to inadequate air cir-

culation.

• The system will not comply with FCC and VDE re-

quirements for electrostatic shielding, and may pro-

duce electrical interference that affects other equip-

ment.

• The system is susceptible to electrical interference

or damage from external sources.

2.6.1 Connecting Terminals and Serial Printers

You can connect up to 16 terminals and/or serial printers for each CXA16

or CXB16 module installed in the system. If the site has been prepared

properly, the lines for the additional terminals and printers are clearly

labeled, and terminate near the system.

You do not connect the terminals and printers directly to the system,

but to a cable concentrator (H3104), which has connections for up to

eight terminals and printers. You then connect the cable concentrator

to the system with a BC16D cable. Two H3104 cable concentrators and

two BC16D cables for each CXA16 module are shipped with the CXA16

module.

Connect the additional terminals and printers as follows:

1. Find the H3104 cable concentrator and BC16D cable (see Fig-

ure 2–12.
