3.5 Common Logic Module (CML/NM) Setting &
Installation
Prior to inserting the CML/NM module card, the following switch-settings
must be set (details of each strap selection are given in Table 3-1):
DCE-DTE
Set to DCE for direct connection to a RADview management station.
Set to DTE for connection via a modem link.
Bit Rate
Set the bit rate used on the RS-232/V.24 link connected to the RADview
station (dipswitch selection can be 1,2, or 3 bits).
Power Supply
An optional redundant power supply is available for additional reliability.
Each power supply can support a fully loaded RADring hub. If the hub is
configured with a redundant power supply, the user must ensure that both
switches on the CML or CML/NM module are placed in the same position
and that each power supply is switched ON. If ordered with a single power
supply, the appropriate switch must be set to ON.
Once all the straps have been set for the desired application, the following
installation procedures should be carried out before inserting the module:
1. Before plugging in the electricity, the user must specify which of the two
power supplies will be used and set the appropriate switch.
2. When the unit has been turned on, LAMP TEST should be performed in
order to check that all the indicators are functioning properly. It is
advised to press RESET in order to initialize the hardware and software.
3. If the CML/NM Management System has been ordered, the user must
first connect the connector to the supervisory port, either from the front
of the card or from the back of the RADring enclosure. If for any reason
the management address or bit rate of the CML/NM needs to be
changed during a system operation, the following steps can be carried
out:
a. Remove the card and set the switches to the required position
b. e-insert the card in the proper slot of the RADring hub
