INSTALLING THE HMU-319 WITH HLU-319, H2TU-C-319, H4TU-C-319
Install the line units (HLUs) into slots 1 through 22 and the HMU-319 management unit into slot 23 of the HMS-318 List 3 shelf (see “HMS-318 List 3 Shelf - Front View” on page 1-2for slot location).
Install HMU and HLU Procedure
Use anti-static wrist-straps connected to the ESD Jack (located on the right adapter bracket, see Figure 1 on page 3) when inserting a circuit card. Avoid touching components on the circuit card.
1Hold the HLU and HMU vertically with the front of the circuit card toward you. Align the top and bottom edges of the HLU and HMU with the HMS-318 List 3 shelf slot guides.
2Slide the HLU and HMU into their respective slots.
3Press the HLU and HMU firmly into the connector until it is seated into the edge-connector on the shelf backplane.
Note: The HLU and HMU will power up with various status LEDs and displays indicating power up status (refer to the HLU-319,H2TU-C-319, or H4TU-C-319 Technical Practice and HMU-319L7V32 and L9V32 User Manual, catalog number LTPH-UM-1142 in the “Related Publications” on page ix for the proper power-up descriptions).
INSTALLING LPS-300C POWER MODULE
Install the LoopStar (LPS-300C) Power Modules into slots 1 through 22 [odd numbered slots (1, 3, 5, 7, ... 21) ] of the HMS-318 List 3 shelf (see Figure 1-2 on page 1-3for slot location, “Connecting Span Powered xDSL Circuits to the HMS-318 List 3 Shelf” on page 1-10for Span Powered xDSL Circuit connection, and Appendix A: “Signal and Pin Assignments” on page A-1for pin assignments).
For visual and audible alarm contact operation, install an HMU-319. Refer to HMU-319 L7AV32 and L9V32 User Manual (LTPH-UM-1142).
