3000/3010 System Manual
1.11.2 Connecting High-Speed Cabling
After attaching the high-speed metallic interface to the backplane, data cabling must be
installed from the network to route the high speed signal to the Total Access 3000/
3010 shelf.
For details, go to: DLP-709.
1.12 Connect External Alarm Inputs / Outputs
The Total Access 3000/3010 provides standard bank alarm outputs. Each of the alarms
listed below consists of a three-pin wire-wrap header that connects to the SCU for
alarm management. The SCU provides the necessary electronic circuits for a NO/
COM/NC contact arrangement. The alarms are:
• Critical Audible (CRI-A)
• Major Audible (MAJ-A)
• Minor Audible (MIN-A)
• Critical Visual (CRI-V)
• Major Visual (MAJ-V)
• Minor Visual (MIN-V)
• Spare 1 (AUX 1)
• Spare 2 (AUX 2)
1.12.1 Connect Alarm Outputs
Depending on the vendor equipment employed at the CO, wiring external alarms from
the Total Access 3000/3010 shelf will vary slightly. The important consideration is
whether the external alarm equipment requires a Normally Open (NO) or Normally
Closed (NC) circuit to pass an alarm. After determining what the CO equipment
requires, connection can be made to the equipment from the Total Access 3000/3010
shelf.
For details, go to: DLP-710.
1.12.2 Connect Fan Alarm Input
The Total Access 3000/3010 Fan Unit uses a NO circuit to pass a fan alarm to the
Total Access 3000/3010 shelf if one or more of the three individual fans cease to
operate, or power is lost to the Fan Module itself. Under these circumstances, the
circuit closes, causing a -48 VDC signal to be passed to the Total Access 3000/3010
external alarm input header. The SCU notes the alarm and passes the information
along as appropriate.
For details, go to: DLP-711.
1.12.3 Connect Miscellaneous Alarm Inputs
There are three additional external alarm inputs that can be reported to the SCU on the
