HDX-192 Cooling Kit Installation6
Reconnect Power
To reconnect power to HDX-192 cards:
1 Locate a loose black and yellow HDX card power cable at the
bottom of the unit, and, with the cable connector locking clip
facing down, push the connector into the port until it clicks.
Make sure the connector is securely connected.
2 Repeat to connect a power cable to each additional HDX-192
card, if any.
Connecting the HDX TDM Cable
(For Systems with Multiple HDX-192 Cards Only)
In systems that have more than one card, you must connect all the
HDX cards to each other with HDX TDM cables (custom SATA
cables, also known as TDM “Flex” cables).
Each HDX-192 card has two ports along the top of the card, la-
beled
IN and OUT. Data communication across multiple cards is
achieved by connecting the cable from the
OUT port of the first
card to the
IN port of the next card.
To connect the HDX TDM cable:
1 Connect the end of the HDX TDM cable labeled OUT to the
OUT port of the upper HDX card.
2 Connect the other end of the HDX TDM cable, labeled IN, to
the
IN port of next the HDX card.
3 Connect each additional card (if any) to its preceding card us-
ing additional HDX TDM cables.
Replacing E6L Hardware
After installing the upgraded cards, replace the retaining bracket
and put the core back into the E6L chassis.
To replace E6L hardware:
1 Carefully place the HDX card assembly retaining bracket back
into position (do not disturb the surface of the DSP cards in the
process) and secure it to the bottom of the E6L by tightening
the captive thumbscrew (see Figure 4).
2 Replace the two screws at the top of the bracket (see Figure 5).
3 Before reinstalling the core back into the E6L chassis, check
the position of the power cable at the front end of the core.
• If the cable is already positioned as shown in Figure 26 (be-
hind the multi-pin connector), skip to step 4.
• If the cable is incorrectly positioned as shown in Figure 27,
reposition it behind the multi-pin connector: use your
thumb to release the tab on the back of the large multi-pin
connector and disconnect it, reposition the power cable be-
hind it, and then reconnect the multi-pin cable (should look
similar to Figure 26).
4 Slide the core back into the E6L chassis, making sure the con-
nectors face outward.
When the core is fully seated into the chassis, the two latches
at the bottom of the chassis should be fully collapsed.
5 Tighten the four thumbscrews to secure the core to the chassis.
