Chapter 1 Cisco SFS 3012R Server Switch Overview
Cisco SFS 3012R Server Switch Components
Blower Modules
The hot-swappable blower modules (fans) of your Cisco SFS 3012R Server Switch maintain the internal temperature of your server switch. You do not need to turn off power to the chassis to replace a blower module. You access the blower module from the front (bezel end) of the Cisco SFS 3012R Server Switch chassis as shown in Figure 1-4. Each blower module contains two blowers, so a fully functional system has four functional blowers. Three blowers must be functional for continuous operation.
Figure 1-10shows a blower module.
