Installing a master/subordinate DIMM
CAUTION:
•
Determine the PoE master DIMM and PoE subordinate DIMM before installation. For how to distinguish
them, see
Figure 31 .
• Plug the master DIMM into the master DIMM slot (there is a "Master" mark on the PCB under the slot),
and the subordinate DIMM into 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.
PoE master/subordinate DIMM LSBM1POEDIMMH is applicable to LSQ1FV48SA0 (LSQM1FV48SA0),
LSQ1GV48SA0 (LSQM1GV48SA0), LSQ1GV48SC0 (LSQM1GV48SC0), and LSQ1GV40PSC0
(LSQM1GV40PSC0).
Figure 31 PoE master/subordinate DIMM
(1) A chip is on the master DIMM, but not on the subordinate DIMM.
To install a PoE DIMM:
1. Wear an ESD wrist strap and make sure it has a good skin contact and is well 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.
