Q-Sys™ I/O Card Remove and Replace Procedure
This procedure is for Q-Sys Type 2 I/O Cards only. Card installation should only be done by a trained
and qualifi ed technician.
Tools
• Phillips
screwdriver
• ESD grounded wrist strap
• 1/4” hex driver/socket (not shown) for replacing Q-Sys I/O Cards in positions C through H.
CAUTION!:
An ESD grounded wrist strap must be worn throughout the remove and
replace procedure. The end of the wrist strap should be connected to an unpainted surface
on the product chassis such as the ground stud.
1. Disconnect the AC mains power cord from the Q-Sys Core.
2. Connect and put on the ESD grounded wrist strap.
3. Remove the sheet metal screws securing the lid to the Q-Sys Core chassis. Remove the lid by lifting it
approximately 1” at the rear of the chassis while sliding it towards the back.
NOTE:
To remove an I/O Card in a position below the top two positions (A and B), you
must fi rst remove the appropriate card(s) above it. The following steps apply to both top
and bottom cards.
Refer to
Figure 10
and
Figure 11
4. Locate the I/O Card to be replaced and, except for any Blank Cards, remove the ribbon cable
(Figure
11)
from the card by gently pushing outward on the cable ejector tabs. The connector should be free
of the socket.
5. Remove the two screws securing the I/O Card Mounting Bracket
(Figure 12)
on the rear of the
chassis. Remove the bracket.
6. Remove the I/O Cards: Refer to
Figure 13
.
a. For cards in positions A or B, remove the four Phillips head screws securing the card to the
standoffs. Remove the card. If you are
not
replacing a card in position C through H, skip
to step
7
.
NOTE:
Figure 13
shows both standoffs and screws for illustration purposes. The screws
are only used on cards in positions A and B. All other cards must use the standoffs.
b. For cards in positions C through H, remove the cards in positions A and/or B (step
6.a
), then
remove the four hex standoffs securing the next lower card, and remove the card. Continue this
until you have removed the card you wish to replace.
WARNING!:
Domestic and international safety regulations require that this device
(Q-Sys Cores) be fully confi gured before power is applied. All eight audio I/O card
bays designated A through H , must include a Q-Sys Audio I/O card, or blank Q-Sys
I/O card, and the proper mounting bracket
(Figure 12)
. Failure to properly confi gure
this device will void the warranty.
7. Install the new I/O Card by reversing steps
5
and
6
. Be sure to align and secure the I/O Card
Mounting Bracket before tightening the hex standoffs or card-securing screws.
Complete step
7
and
8
for each single level, or layer, of cards as you replace them. Do not move to the
next level of cards until the lower level is properly installed.
8. Reconnect the ribbon cable to the I/O Card, by aligning the tab on the cable connector housing with the key on the card connector as shown in
Figure 14
. Gently push down on the cable connector housing to seat the cable into the card connector. When properly seated, the cable ejectors
will lock in place with the thumb tabs upright.
