Figure 8-25. SDU-2000 Recommended Slots for DS1 LRM Installation
Use the following steps to install a DS1 Line Re-timing Module in an SDU-2000.
1. Align the module card edges with the plastic card guides of the selected slot.
2. Slide the module into the chassis until it seats fully into the edge connector.
3. Tighten the captive screws located at the top and bottom of the front panel.
Caution: To avoid possible damage or intermittent failure, ensure that
you have completely inserted the module into the shelf and that you
have securely tightened the captive screws. A partially inserted
module can easily become damaged and cause intermittent failures.
Installing a Cut-Through Assembly in the SSU-2000
The SSU-2000 shelf has I/O interface connections on the rear panel for connecting
the SSU-2000 to the corresponding I/O adapter panels. The LRM I/O connections
are made from the 50-pin Micro-D female connectors on the SSU-2000 rear panel,
through the CTA, and to the adapter panel using the appropriate cable. Connectors
J10 through J18 on the rear panel are labeled I/O-1 through I/O-9; each connector
is associated with a specific I/O plug-in module slot. Symmetricom recommends
using connectors J13 through J16, which correspond to module slots A6 through A9
respectively (see
252 SSU-2000 User's Guide
Figure 8-26).
