Cisco Systems VIP4 manual Location, Type Size/Speed Description

VIP4 Overview

Table 2 outlines features of the VIP4 models, and Table 3 provides a list of the VIP4 internal components.

Note You can use any combination of available CPU memory configurations and packet memory configurations on the VIP4. You do not need to have equal amounts of CPU memory and packet memory installed. (For information about upgrading memory, see the “Upgrading VIP4 Memory” section on page 31.)
