Setting up a PoE system (optional)
Requirements
Power over Ethernet (PoE) enables a power sourcing equipment (PSE) to supply power to powered
devices (PDs) from Ethernet interfaces through twisted pair cables. Commonly used PDs include: IP
telephones, wireless LAN access points (APs), and web cameras.
To set up a PoE system for the S7500E series, the following requirements should be met:
Switch and card models supporting PoE
• Except the S7506E-S and its specific SRPU LSQ1SRPA0 (LSQM1SRPA0), all the other models of the
S7500E series can implement the PoE function through the cards listed in Table 10.
• Exc
ept the LSQ1GV48SD0 (LSQM1GV48SD0), all the other cards require a PoE dual in-line
memory module (DIMM) to provide the PoE function. PoE DIMMs fall into two types: 24-port PoE
DIMM LSQM1POEDIMMS0 and PoE master/subordinate DIMM LSBM1POEDIMMH. For the
compatibility between the two types of modules and cards, see Table 10. F
or the installation of a
Po
E DIMM, see “Installing a PoE DIMM.”
T
he 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.
