Air filter

Air filter overview

To prevent dusts from entering the chassis, you can configure air filters for the switch as needed and
install the air filters at the air intakes.
CAUTION:
Clean air filters periodically (at least once every three months) to guarantee adequate ventilation and
avoid over-temperature.

Air filter ordering guide

Different S7500E switches support different air filters. Order air filters compatible with your switch.

PoE DIMM

PoE DIMM overview

The S7500E series switch support various PoE LPUs.
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.
