262 Installing Blade Components
2 Install the FlexMem Bridge in the socket.
CAUTION: Positioning the card incorrectly can permanently damage the card and
the system board when you turn on the system. Be careful not to bend the pins on
the LGA socket.
a
Identify the pin-1 corner of the card by locating the tiny gold triangle
on one corner of the card. Place this corner in the same corner of the
ZIF socket identified by a corresponding triangle on the system board.
b With the pin-1 corners of the card and socket aligned, set the
processor lightly in the socket.
Because the system uses a ZIF processor socket, do not use force.
When the card is positioned correctly, it drops down into the socket
with minimal pressure. See Figure 3-51.
c Close the processor shield.
d Tighten the screw to secure the processor shield.
3 Close the blade. See "Closing the Blade" on page 161.
4 Install the blade. See "Installing a Blade" on page 158.
HT Bridge Card (PowerEdge M905 Only)
An HT (hypertransport) bridge card must be installed in the third and fourth
CPU sockets on the PowerEdge M905 system board.
Consequently, if you replace the system board, you must transfer the HT
bridge cards to the replacement planar.
Removing an HT Bridge Card
1 Remove the blade. See "Removing a Blade" on page 155.
2 Open the blade. See "Opening the Blade" on page 159.
3 Pull the socket-release lever straight up until the bridge card is released
from the socket. See Figure 3-54.
4 Open the processor shield and then lift the card out of the socket.
