Chapter 1 Cisco 7500 Series Product Overview
AC-Input and DC-Input Power Supply Overview
Caution To prevent system problems, do not mix power supply input types in the Cisco 7507, Cisco
7507-MX, Cisco 7513, Cisco 7513-MX, or Cisco 7576 routers. Both power supplies installed in a
router must be either AC input or DC input. Do not attempt to install a DC-input power supply in a
router with one AC-input power supply, or vice versa.
The DC-input power cable is not available from Cisco Systems; however, it is available from commercial
cable vendors. DC-input power cable specifications are listed in Table 1-1 (Cisco 7505), Table 1-2
(Cisco 7507), Table 1-3 (Cisco 7507-MX), Table 1-4 (Cisco 7513), Table 1-5 (Cisco 7513-MX), and
Table 1-6 (Cisco 7576).
