3. Frames
Overview
Control Cards
The frame has 2 control card slots. A control card can be an EM0374 (router control card) or an
EM0414 (clock generator card). The EM0374 is required if (1) an MFR is present in the frame or
(2) an NV9000 router control system is connected.
The frame requires only one control card. A second control card is for redundancy. When a second-
ary control card is present, the master control system will automatically switch to the secondary
card if the first one fails.
S
Redundant control cards are not supported by all third-party router control protocols. Please
contact Miranda if you have questions about this.
The EM0374 control card can process control information from an external router control system
such as the NV9000. The EM0374 also manages various reference signals. The EM0374 supplies
appropriate timing and control signals to the I/O cards and the MCPMs in the frame. So does the
clock generator card (EM0414), although it does not support any routers.
The control card(s) also handle alarm signalling.
Power Supplies
The frame has two power supply bays (one for redundancy) and a fan tray at the top of the frame.
The power supplies are PS6100s

.
Frame Cooling
A pull-out fan tray at the top of the frame provides a quiet flow of ambient air through the frame to
ensure cool and reliable operation. Periodic maintenance of the air filter will help maintain system
reliability. Refer to
Maintenance
on page 205 for more information.
S
For proper air flow, keep the door closed during operation and place cover plates over unused
slots at the rear of the frame.
2. Older frames in the field might still use PS6000 power supplies.
