Connecting Timing (Clock) Cables
Timing cables are connected to the T3 and T4 connectors of the
ECU300/ECU300-F. Each cable is terminated in a 9-pin D-type female
connector.
To connect a timing cable to the XDM-300 shelf:
1. Route the timing cables along the side of the rack to the appropriate
XDM-300 shelf (see "
Connecting Fibers and Cables in ETSI A Racks " on
page 3-85 ).
2. Pull each cable down to the level of the corresponding ECU300/ECU300-F
and bend it until the cable connector is positioned against the appropriate
timing connector on the ECU300/ECU300-F.
3. Connect the free ends of the cables in accordance with the rack installation
plan and the cable tags, to connectors T3 and T4 on the
ECU300/ECU300-F.
C
AUTION
:
Do not exert excessive tightening torque to
secure the cable connector, as this may damage the
ECU300/ECU300-F.
4. Secure each cable connector using its two screws.
5. Use cable ties as required to fasten the cables to the rack side rails.
Connecting Management Cables
The management cables are connected to the RJ-45 connectors designated
MANAGEMENT MAIN and PROT/LCT on the ECU300/ECU300-F. Each
cable is terminated in an RJ-45 plug.
The cable from the management station must be plugged into the
MANAGMENT MAIN connector in the ECU300 or ECU300-F card.
If more than one shelf has to be connected to the management, a daisy chain
interconnection is used to distribute management to the shelves for either
ECU300 or ECU300-F cards. In this configuration, the cable from the
management station is connected to the MANAGEMENT MAIN connector of
the first shelf, the PROT/LCT connector of the first shelf is connected to the
MANAGEMENT MAIN connector of the second shelf, and so on.
