Rack Mounting Procedure

To secure the HMS-318 List 3 shelf to the telco-style rack, you must use the mounting screws provided or follow your local practices for installing the shelves into your telco-style equipment rack. Ensure that the adapter brackets have been securely fastened [see “Adapter Bracket Mounting Procedure (19-inchTelco-style Equipment Rack)” on page 2-5, “Adapter Bracket Mounting Procedure (23-inchTelco-style Equipment Rack)” on page 2-5, or “Adapter Bracket Mounting Procedure (ETSI-style Equipment Rack)” on page 2-6for more information].

Perform the following procedure to mount the HMS-318 List 3 shelf into a telco-style equipment rack.

IMPORTANT To prevent injury, review the “Safety Guidelines” on page xi and the “Special Rack-Mounting

!Precautions” on page 2-4before installing the HMS-318 List 3 shelf in the telco-style equipment rack.

Step

Action

1

Locate the telco-style equipment rack position you plan to install the HMS-318 List 3 shelf into.

 

 

2

Verify that there are no obstructions and ensure that the telco-style equipment rack is stabilized.

 

 

3

Position the shelf in the telco-style equipment rack lining up the bracket holes on the shelf with the holes

 

on the rack and secure with the four #12-24 x .375 inch mounting screws (see Table 2-1 on page 2-2).

 

Note: The vertical spacing for EIA racks is 1.75 inches (4.44 cm), with mounting holes

 

spaced 1.5 inches (3.81 cm) apart. Vertical spacing for WECO racks is 2.0 inches (5.08 cm),

 

with mounting holes spaced 1.0 inch (2.54) apart.

 

 

4

Tighten the screws using a 1/4-inch flat-blade screwdriver.

 

 

5

You are now ready to begin interconnecting the communications cables that apply to your application

 

(see “DSX-1 and HDSLx Connections” on page 2-7or “Span Powered xDSL Connections” on page 2-8).

 

 

DSX-1AND HDSLX CONNECTIONS

Perform the following procedure to connect the DSX-1 and HDSLx interface cables to connectors P1, P2, P3 and P4 (see Figure 1-2 on page 1-3for connector location and “Connecting to HDSL, HDSL2, and HDSL4 Circuits” on page 1-8, for connector descriptions).

DANGER

Before making both DSX-1 and HDSLx connections to the HMS-318 List 3 shelf, ensure that the

Main CO power breaker is off. Otherwise, severe injury to the installer or damage to the unit may

 

 

result.
