4. Unpack the 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 PoE DIMM and push

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 card 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 .
