Cisco 7604 Router
The Cisco 7604 router chassis has four horizontal slots that are numbered from top to bottom (See
Figure 1-5
).
Slot 1 is reserved for the supervisor engine, which provides switching, local and remote management,
and multiple GBIC uplink ports.
Slot 2 can contain a redundant supervisor engine that can act as a backup if the first supervisor engine
fails. If a redundant supervisor engine is not required, slot 2 is available for an OSM or other supported
Catalyst 6500 series modules.
Note
Both supervisor engines in a single chassis must be identical.
