functioning, you can swap the other out for maintenance with no disruption to the
operation of the interconnect. When powered up, normal operation of each QM561
power supply unit is indicated by the illumination of the following LEDs:

7.3.9 Connecting Federated Interconnects to an External Clock Source
The connection to the clock box depends on whether the interconnect has a single
controller card or dual controller cards.
_________________________ Note _________________________
All clock I/O connections must be made using QM584 CAT–VE
double-screened (foil and braid) cables approved by Quadrics.
7.3.9.1 Connecting a Single QM503 controller Card
If the interconnect is part of a federated switch, connect QM584 clock cables to the
QM503, installed in slot Ctrl A, as follows:
1. Connect the Pri Clk input on the QM503 to a clock output from a QM580 clock
distribution box that is configured as a Master.
2. If the federated switch has more than one QM580 clock distribution box,
connect the Sec Clk input on the QM503 to a clock output from a QM580
that is configured as a Slave.
7.3.9.2 Connecting Dual QM503 controller Cards
If the interconnect is part of a federated switch, connect QM584 clock cables to the
dual QM503 controller cards as follows:
1. Connect the Pri Clk input on the QM503 in slot Ctrl A to a clock output from a
QM580 clock distribution box that is configured as a Master.
2. Connect the Pri Clk input on the QM503 in slot Ctrl B to a clock output from a
QM580 clock distribution box that is configured as a Slave.
3. Do not connect the Sec Clk inputs on either of the QM503 modules. See
Chapter 6.
7.4 Configuring the QM503 controller Card
To verify that the interconnect is cabled to each QM580 clock distribution box
correctly and that it is operating correctly, the operating mode of the QM503
controller card in slot Ctrl A must be configured. Note that the QM503 in slot
Ctrl B (if fitted) is configured automatically to match. To configure the operating
mode of the QM503, follow these steps:
1. Connect a VGA monitor and keyboard to the QM503 using the connectors
labeled VGA and Kybd respectively. Alternatively, use a Null modem cable
to connect the COM port of a PC to the serial port connector labelled COM 1.
Configure the comport for 9600 Baud, no parity, 8 bits and 1 stop bit. Use a
terminal emulator program to open a connection.
