sides with both hands to support its weight, and then place it on a flat stable surface.
When you begin pulling, the latching mechanism arms extend from the NSM module and lock in their
fully extended position.
4. Loosen the NSM module cover thumb screw and open the cover.
5. Physically locate the failed boot media.
The boot media is located along the shelf chassis wall opposite from the power supply. The boot media
attention (amber) LED, located on the board next to the boot media slot, is illuminated.
The LED remains illuminated for 10 minutes after you remove the NSM module from the
shelf.
6. Replace the boot media:
a. Using the Phillips #1 screwdriver, carefully remove the screw securing the bottom (notched) end of the
boot media to the board.
b. Remove the boot media by rotating the notched end up slightly and then gently pulling it towards you
until it releases from the socket.
You can hold the boot media by placing your thumb and forefinger on the side edges, at the notched
end.
c. Unpack the boot media from the antistatic bag.
d. Insert the replacement boot media by pushing it gently into the socket until it is seated squarely and
completely in the socket.
You can hold the boot media by placing your thumb and forefinger on the side edges, at the notched
end. Make sure that the side with the heat sink is facing up.
When correctly seated, and when you let go of the boot media, the notched end of the boot media is
angled up, away from the board, because it is not yet secured with the screw.
e. Gently hold down the notched end of the boot media as you insert and tighten the screw with the
screwdriver to secure the boot media in place.
Tighten the screw just enough to hold the boot media securely in place, but do not
overtighten.
7. Close the NSM module cover, and then tighten the thumb screw.
8. Reinsert the NSM module into the shelf:
a. Make sure that the latching mechanism arms are locked in the fully extended position.
b. Using both hands, gently slide the NSM module into the shelf until the weight of the NSM module is
fully supported by the shelf.
c. Push the NSM module into the shelf until it stops (about half an inch from the back of the shelf).
You can place your thumbs on the orange tabs on the front of each finger loop (of the latching
mechanism arms) to push in the NSM module.
d. Loop your index fingers through the finger holes of the latching mechanisms on either side of the NSM
module.
