Cisco 7513, Cisco 7513-MX, and Cisco 7576 Blower Module Assembly
The Cisco 7513, Cisco 7513-MX, and Cisco 7576 use a blower module assembly that is located at the
top rear-end of the chassis (see
Figure 1-33
and
Figure 1-34
). The assembly supplies cooling air to the
chassis interior. The blower module assembly also contains the system LEDs, which are located on a
nonremovable printed circuit card at the rear of the interior of the blower module assembly. (A spare
blower module assembly ships as Product Numbers MAS-7513-FAN= for the Cisco 7513 and Cisco
7513-MX and MAS-7576-FAN= for the Cisco 7576.) For blower module assembly maintenance
