scope of this manual, however basic instructions on wiring the alarm connection for external moni-
toring is provided. See
In addition to an alarm connection, the NV8288 is connected to a router control system that
receives status information from the router’s control card(s). (See
on page 12.) The control card reads the status of NV6257’s power supply and fans through the
‘Power Supply Monitors’ connection. (See
on page 6.) In addition, the control card
monitors the router’s power supply, fans, and video reference connections. Both NV6257 and
router information is communicated to the router control system and viewable using UniConfig.
(See the UniConfig User’s Guide.)
The alarm connection is labeled ‘ALARM’ and is located on the rear of the router, as shown in
Figure 2-14. For instructions on making alarm connections, see
Figure 2-14. System Alarm Connection (Rear View)
Active Cards
The NV8288 and the NV8288-Plus feature several active cards that manage incoming signals, for-
warding of commands from the control system, perform signal switching, and distribute outgoing
signals. Each card has a colored ejector lever that matches the colored card guide on the slot into
which the card is installed.
The NV8288 and the NV8288-Plus both feature:
• 1 or 2 control cards (one optional for redundancy)
• 24 input cards
• 48 output cards
• 1 or 2 crosspoint cards (depending on configuration)
• 1 monitor cardset (composed of 2 cards)
Each card and function is described in the following section. For information on installing cards,
see
Control Cards
The router has two control cards (EM0529), one primary and one secondary (optional for redun-
dancy). Each card receives commands from the control system (e.g., NV9000), and in turn, controls
the input, output, crosspoint and monitor cards. Only one control card is active at a time, with the
active card updating the stand-by card.
