9926-XHTOS PRODUCT MANUAL 9926-xHtoS-OM (V1.2)
CAUTION
If required, make certain Rear I/O Module(s) is installed before installing the
9926-xHtoS into the frame slot. Damage to card and/or Rear I/O Module can
occur if module installation is attempted with card already installed in slot.
Note: Check the packaging in which the 9926-xHtoS was shipped for any extra
items such as a Rear I/O Module connection label. In some cases, this label
is shipped with the card and to be installed on the Rear I/O connector bank
corresponding to the slot location of the card.
Install the 9926-xHtoS into a frame slot as follows:
1.
Determine the slot in which the 9926-xHtoS is to be installed.
2.
Open the frame front access panel.
3.
While holding the card by the card edges, align the card such that the
plastic ejector tab is on the bottom.
4.
Align the card with the top and bottom guides of the slot in which the
card is being installed.
5.
Gradually slide the card into the slot. When resistance is noticed, gently
continue pushing the card until its rear printed circuit edge terminals
engage fully into the rear I/O module mating connector.
CAUTION
If card resists fully engaging in rear I/O module mating connector, check for
alignment and proper insertion in slot tracks. Damage to card and/or rear I/O
module may occur if improper card insertion is attempted.
6.
Verify that the card is fully engaged in rear I/O module mating
connector.
7.
Close the frame front access panel.
8.
Connect the input and output cables as shown in 9926-xHtoS Rear I/O
Modules (p. 2-4).
9.
Repeat steps 1 through 8 for other 9926-xHtoS cards.
Note: • The 9926-xHtoS BNC inputs are internally 75-ohm terminated. It is not
necessary to terminate unused coaxial inputs or outputs.
• External frame sync reference signals are received by the card over a
reference bus on the card frame, and not on any card rear I/O module
connectors. The frame has BNC connectors labeled
REF 1
and
REF 2
which
receive the reference signal from an external source such as a house
distribution.
• To remove a card, press down on the ejector tab to unseat the card from the
rear I/O module mating connector. Evenly draw the card from its slot.
