Chapter 1: Product Description

POWER AND ALARM CONNECTIONS

The HMS-318 List 3 shelf has a separate split input power (TB1) and an Alarms wire-wrap field (TB2). The following paragraphs provide information about TB1 and TB2.

Safety Precautions

Observe the following general precautions and recommendations in planning the source power requirements for the HMS-318 List 3 shelf (for additional safety information, please refer to the section describing the “Safety Guidelines” on page xi):

Check the power at your site before shelf installation (and periodically after installation) to ensure clean power is being received.

Always disconnect the power source and unplug all the power cables before working on the shelf.

Install proper grounding for the site to avoid damage from lightning and power surges.

DANGER

To avoid electrical shock, be careful when working near power supplies. Telco equipment uses -

48 Vdc office power.

 

Input Power Terminal Block

 

Before making any power connections (CO primary power feeds A and B) to the HMS-318 List 3

CAUTION

shelf, ensure that the Main CO power breaker is off. Otherwise, severe injury to the installer or

 

 

damage to the unit may result.

The 5-position input power terminal block (TB1, see Figure 1-3) provides a central connection point for the CO primary power feeds (A and B).

HMS-318 List 3 Shelf Input Power Connections

The input power terminal block supports split -48V battery power bussing. Slots 1 through 11 on the HMS-318 List 3 shelf are powered by the -48 Vdc A bus (labeled -48VA). Slots 12 through 22 are powered by the -48 Vdc B bus (labeled -48VB). The two GND terminals are tied together. In the HMU/HLU configuration, the HMU-319 is diode- OR’ed to both power busses, to guard against power failure in the event that one power supply is lost. This feature requires the two ground terminals to be tied together on the HMU card (for proper power and grounding of the HLU- 319 and HMU-319, see “Related Publications” on page 1-ixand choose the most appropriate instruction manual for your product).
