4-16 Hardware installation: Intelligent Peripheral Equipment module

553-4001-111 Standard 1.0 March 1997

Expansion cabinet

If you are installing your Meridian MAX IPE/IPE-E module into an Option

11 expansion cabinet, the process is very similar to an installation in the

main cabinet.

Two shielded four-port cables are used to connect the Meridian MAX

IPE/IPE-E to its supervisor workstation, printers, and other peripheral

devices. Cable A (NT1R03AA) has a 50-pin key telephone connector on

one end and four DB-25 female connectors on the other, as well as an

additional Ethernet port, shown in Figure 4-14. Cable B (NT1R03BA) is

identical to Cable A except that it has no additional Ethernet port, shown in

Figure 4-14. Each of the eight DB-25 connectors can connect to a

peripheral device. Cable A services Ports 1, 3, 5, and 7. Cable B services

Ports 2, 4, 6, and 8. Refer to the Communication Port Assignment Sheet

(Table 4-4) when connecting peripherals to cables.

Underneath the expansion cabinet of the Option 11 is a connector panel

with 10 numbered connector ports. Each connector port connects to the

corresponding numbered slot directly above, inside the expansion cabinet.

The key telephone connectors of each four-port cable are connected here.

These connectors are held in place by a removable connector panel bar.

The connector panel assignment for Cable A (NT1R03AA) and Cable B

(NT1R03BA) in the Option 11 is shown in Table 4-3. The connector panel

assignment depends on the desired slot placement of the Meridian MAX

IPE/IPE-E module.

Before connecting the four-port cables, connect one extension cable

(NT1R03CA) to each connector, then connect each four-port cable. Make

sure the connectors are secure. This allows the front panel on the Option 11

to be closed without interference from too many dangling cables. For

example, if your Meridian MAX IPE/IPE-E module occupied slots 14, 15,

and 16, connect one end of an NT1R03CA extension cable to connector J16

while connecting Cable A to the other end of the extension cable. Connect a

second NT1R03CA extension cable to connector J14, attaching Cable B to

the other end of the second extension cable. Connector J15 is not used.

Replace the connector panel bar making sure the padded side is placed

against the back of the connectors.
