Installing the LSBM1POEDIMMH
CAUTION:
•
Determine the PoE master DIMM and PoE subordinate DIMM before installation. For how to distinguish
them, see
Figure 32 .
•
Install the master DIMM in the master DIMM slot (there is a "Master" mark on the PCB under the slot), and
the subordinate DIMM in the subordinate DIMM slot (there is a "Slave" mark on the PCB under the slot).
•
The master and subordinate DIMMs must be used simultaneously. The PoE system operates correctly only
when both of them are inserted in the correct slots.
Figure 32 PoE master/subordinate DIMM
(1) A chip is on the master DIMM, but not on the subordinate DIMM.
To install the LSBM1POEDIMMH:
1.
Wear an ESD wrist strap and make sure it has a good skin contact and is reliably grounded. For
more information, see "
Attaching an ESD wrist strap ."
2.
Make sure the module is sturdy. Then find the PoE DIMM slot (there is a "Master" mark on the
PCB under the slot) on the PCB.
3.
Pull the white clips on the two sides of the PoE DIMM slot outward, as shown by callout 1
in
Figure 31 .
4.
Unpack the master PoE DIMM, and align the golden plating of the PoE DIMM with the groove
on the slot.
5.
As shown by callout 2 in Figure 31 , use your thumbs to press the edges of the master PoE
DIMM and push it along the guide rail into the slot until the white clips click into the grooves on
the two sides of the PoE DIMM.
6.
Verify that the clips lock the master PoE DIMM.
7.
Repeat steps 3 through 6 to install the subordinate DIMM in the subordinate DIMM slot (there is
a "Slave" mark on the PCB under the slot).
