The lower card cage, located behind the air filter, has five horizontal slots for switch fabric cards.
Below the lower card cage is a power supply bay. Up to four AC-input power supplies or two
DC-input power supplies can be installed in the bay.
A cable-management system manages the line card interface cables in the upper card cage, keeping
them organized and free from sharp bends, which can degrade cable performance. The Cisco 12012
cable-management system consists of two components: a horizontal cable-management tray, which
is attached to the frame directly above the upper card cage, and a vertical cable-management bracket,
which is attached to each line card. (Refer to Figure 2.)
The horizontal cable-management tray keeps the interface cables organized by upper card cage slot
and free of sharp bends as the cables enter the Cisco 12012 from either the left or right side and are
routed to the individual line cards.
