NEC nd-20292 manual Electra Markii

1.Attach the wall mounting bracket to the RAA-E

-.Unit with the screws provided, as shown above in Figure 920-3.

2.Locate the R,AA-E Unit with mounting bracket on the wall in the desired position.

3.Using the wall mounting bracket, already attached to the RAA-E Unit, as a template, mark the location of the wall mounting screws (A and B).

4.Using Number 8 pan head wood screws, insert the screws into the positions marked. Do not tighten the screws all the way, leave enough room for the bracket to be placed over the screw head.

6.Place the RAA-E Unit with mounting bracket attached onto the mounting screws and secure it to the wall by tightening the screws (A and B).

920.3CONNECTING the RAA-E to the

ELECTRA MARKII

1.The RAA-E Unit is connected to the system via a standard modular line cord (not provided). Connect one end of the modular line cord to the modular jack (RJllC) located at the rear of the RAA-E Unit (labeled line).

2.Connect the other end of the modular line cord to a modular jack (RJllC) connected to an ESI-E( 1 station port of the system at the MDF J-blocks.

NOTE 1: The Electra Mark11 System may have up to four programming station ports. The first two are permanently assigned to the first two ports of the first ESI-E( ) ETU. The third position can be assigned by either of the first two programming stations to be any ESI-E( ) ETU port supporting an ETE-16D-

( ). When connected, the fourth programming assignment is for the RAA-E Unit. (See Chapter 3, Programming, Memory Block lE2). The RAA-E maintains its programming port status, even after an extended power loss or after a 1st initialization occurs.

NOTE 2: Ensure that all the RAA-E switch settings are correct before plugging in the RAA-E modular jack.

NOTE 3: If the RAA-E is connected to an Attendant port the RAA-E will gain Attendant Programming features.

920.5CONNECTING the MODEM to a LINE

It is possible to dedicate a CO line to an on site modem for remote administration purposes. However, it is recommended that the modem be connected to a single line port of the system. When calling in to use the

Remote Administration Adaptor, the System Attendant can transfer the calling party (programmer) to the station number associated with the SLI port connected to the modem.

A trunk may be programmed to terminate directly to the single line port, thereby eliminating the need for
