CTM SD Card Installation Guide 3
Removing the Installed SD Card
To remove the installed SD card:
1Orient the CTM as shown below, with the top of the CTM
closest to you.
2Locate the currently installed SD card. If necessary, carefully
move the cable out of the way as shown below.
3Using a finger, carefully push the SD card straight in to release
its latch.
4Using a pair of small long-nose pliers, slowly pull the card out
of the CTM. Keep the card horizontal while removing it.
Installing the New SD Card
After removing the original SD card, install its replacement card.
To install the new SD card:
1Using a pair of small long-nose pliers, hold the new SD card
with the contacts facing up (the same orientation as the card
you removed), align the SD card with its socket and gently
push it part of the way into its socket. Keep the card horizontal
so it remains parallel with the circuit board.
2After the card is half way in, release the pliers and set them
aside.
3Using a finger, gently push the new SD card the rest of the way
into its socket. Make sure it seats correctly and that its latch en-
gages, indicated by a click sound.
Reassembling the CTM
After installing the new SD card, do the following to reassemble
the CTM.
1If necessary, return the cable you moved out of the way earlier
to its original position.
2Place the back cover on the CTM, making sure it is oriented
correctly and that no cables are caught under the edge of the
back cover.
3Push the back cover towards the side with the power and RJ45
connectors, so that it aligns with the mounting holes in the
CTM.
4Using a 5.5mm (7/32-inch) Hex driver, reinstall the nine (9)
M3 hex nuts to secure the back cover to the CTM.
