• To supply power through PoE, you must install a PoE dual-in-line memory (DIMM) module on the PoE
LPU and implement the PoE function on the LPU.
• When a PoE LPU is not installed with a compatible PoE DIMM module, the Ethernet ports on the LPU
cannot supply power through PoE, and are common Ethernet ports.

NOTE:
•
The model of a card is LSQM-prefixed on the card package and LSQ-prefixed on the card panel. For
example, LSQ1GV48SD0 and LSQM1GV48SD0 identify the same card. When you order a card, you
refer to the card by its LSQM-prefixed model. In this chapter, the card models are LSQ-prefixed, the
same as marked on the card panels.
• The PoE powering types include type 1 and type 2:
{
Type 1–A port provides power of 0 to 15.4 W, voltage of 44 V to 57 V, and maximum current of 350 mA.
This type is applicable to class 0 through class 3 PDs.
{
Type 2–A port provides power of 0 to 30 W, voltage of 50 V to 57 V, and maximum current of 600 mA. This
type is applicable to class 0 through class 4 PDs.
NOTE:
The LSQ1GV48SD0 and LSQ3GV48SC0 each can provide a maximum of 806 W power through PoE.
When you use the cards to power devices through PoE, make sure the total power of PDs does not exceed
806 W.
CF cards
CF card overview
On an SRPU with a CF card interface, you can install a CF card to expand the storage space for the
device. A CF card can save startup files, configuration files, and logs.
