OID | MIB Object | Description | Access | |
|
|
|
| |
.1.4.10 | cgmClkDistMode | The clock distribution mode of the module. | r/w | |
|
| There are four main modes a module can be |
| |
|
| operated in: |
| |
|
| z | Distributed Mode (0) |
|
|
|
| For each clock domain (CLK1/2/3), the |
|
|
|
| module selects a payload card in the shelf |
|
|
|
| and replicates it to the other payload cards. |
|
|
|
| The selection can be done manually or |
|
|
|
| automatically. |
|
|
|
| Not applicable for |
|
|
| z | Extension Mode (1) |
|
|
|
| The module receives CLK1/2 from the main |
|
|
|
| shelf and distributes them to the local |
|
|
|
| payloads. Reference clocks (CLK3) can be |
|
|
|
| routed to the main shelf. |
|
|
|
| Not applicable for |
|
|
| z | Buffer Mode (2) |
|
|
|
| The module receives CLK1/2/3 from the |
|
|
|
| main shelf and distributes them to the local |
|
|
|
| payloads. |
|
|
|
| Not applicable for |
|
|
| z | Centralized Mode (3) |
|
|
|
| The module generates the T0 clocks based |
|
|
|
| on internal or external references. In |
|
|
|
| centralized mode there may be up to two |
|
|
|
| shelves connected, operating in either |
|
|
|
| extension or distribution mode. |
|
|
| z Extended Centralized Mode (4) |
| |
|
|
| Like centralized mode, except that CLK3 is |
|
|
|
| routed to the main shelf via the |
|
|
|
| connector (i.e. REF A/B can not be selected |
|
|
|
| as input). |
|
|
|
| Not applicable for |
|
|
| Default value is centralized mode (3). |
| |
|
|
|
| |
.1.4.11 | cgmExtChConnection | In centralized mode, selects the properties of the | r/w | |
|
| connections to extension chassis 2 and 3 (not |
| |
|
| connected, extended mode or buffered mode): |
| |
|
| Single Chassis (0) |
| |
|
| Chassis 2 in extension mode (1) |
| |
|
| Chassis 3 in extension mode (3) |
| |
|
| Chassis 2 and 3 in extension mode (5) |
| |
|
| Default value is (0). |
