z
Optical transceivers are optional components and are not supplied with the WX3000 series. Use
H3C-recommended optical transceivers. For details about the technical specifications of SFP
optical transceiver, refer to Appendix A.
z
The WX3024 supports all XFP optical transceivers except those requiring –5.2 V power supply.
z
The BIDI optical transceivers must be used in pairs. For example, if an SFP-GE-LX-SM1310-BIDI
is used at one end, an SFP-GE-LX-SM1490-BIDI must be used at the other end. The same is true
for FE BIDI modules.
RPS
When the AC power supply fails, an RPS unit can feed power to maintain the normal operation of the
system.
z
The WX3010 and WX3008 do not support the RPS unit.
z
An RPS unit is an optional accessory to be separately orderly if needed.
z
For the RPS unit installation information, refer to section Connecting the RPS Cable on page 3-19.

DC power cables are optional accessories to be separately order if needed.
z
The DC power cables should be shorter than 3 meters (9.84 ft.) to minimize voltage attenuation.
Fans
The WX3024 is equipped with five fans: two fans for heat dissipation of the main board and three fans
on the power module for heat dissipation of the power supply system.
