Replacement procedures
All components of the S7500E series switches are hot swappable. You can replace any of them when the
switch is running.
CAUTION:
When replacing pluggable modules when the switch is running, notice safety with electricity.
This chapter includes these sections:
• Replacing a power module
• Replacing a card
• Replacing a fan tray
• Replacing an air filter
• Replacing a CF card
• Replacing a transceiver module
• Replacing the PoE DIMM
Replacing a power module
Replace a power module in the following cases:
1. The power module is faulty.
2. The power of the current power module cannot satisfy the power requirements of the switch.
• The power module does not support PoE, or the PoE output power of the power module cannot
satisfy the PoE power supply requirements. To ensure normal operation of the connected PDs, use a
power module with a higher power. For power module ordering information, see the chapter
“Appendix B Pluggable module ordering guide.”
• Select a 3-RU high power module for the S7503E, S7506E-S, S7506E, and S7506E-V. You can also
use a PSR650-A/PSR650-D power module (1 RU high) together with a PWR-SPA power adapter to
supply power to the switch when the system power consumption is no higher than 650 W. When
the power of the power module cannot satisfy the system power consumption of the switch or PoE
power supply is required, replace the power module with a 3-RU high power module, and remove
the power adapter. For more information about power module ordering, see the chapter “Appendix
B Pluggable module ordering guide.”
NOTE:
• For how to calculate PoE power consumption, see the chapter “Appendix A Hardware specifications.”
• The system power consumption is the total dynamic power consumption of all SRPUs plus the total
dynamic power consumption of all the LPUs plus the maximum power consumption of fans. For more
information, see the chapter “Appendix A Hardware specifications.”
