Using MRC
Selecting a Control Card
Typically, control cards are selected from the Control Cards tab. However, on the ‘Switch Points’
page and ‘Module Types’ page, only hybrid routers are configurable so it is the Hybrid Routers
tab that you use.
How To Select a Control Card
In the ‘Network Frame Summary’ section, click the Control Cards tab (or the Hybrid Routers
tab) to bring the page forward. Then click the radio button on the row listing the control card
you want. Control cards are identifiable both by name and by IP address.
Note: merely clicking on a row listing a control card highlights the row, but does not select the
control card.
Control Card State Indicators
Control cards are listed one per row. On each row, a colored dot appears in the Online column.
The color of the dot indicates the state and type of card, as follows:
• Green — the control card is functioning normally. Communication between MRC and the
router is good and without interruption.
• Yellow — the control card is in an “unhealthy” state even though no interruption in commu-
nication between MRC and the router has occurred. You can open the ‘System Status’ page
to view diagnostic messages. (See
System Status on page 115.)
• Red — the control card is in a faulty state and all communication has been stopped. You can
open the ‘System Status’ page to view the extent of failure. (See System Status on page 115.)
• Grey — the control card is offline and MRC cannot communicate with it.
• Blue — represents a virtual control card. A “virtual” control card is one that does not physi-
cally exist but for which there is a configuration. (See Creating Virtual Control Cards on
page 133.)
A (black) lock icon indicates that a control card configuration has been locked. For details, see
Locking and Unlocking Configurations on page 136.
IMPORTANT
Each control card in a router must be configured separately and identically.
With two control cards, one control card is active and the router can remain operational
while configuration changes are being made to the inactive control card.
