Cpu, Cage; Cpu Utilization; Active Sessions; Throughput - Cisco VPN 3000 User Manual

Fan 1, Fan 2
The VPN Concentrator includes two cooling fans. In the Model 3005, they are on the rear of the chassis,
with Fan 1 on the left as you face the rear. In the Model 3015–3080, they are on the right side of the
chassis as you face the front, with Fan 1 closest to the front. This table shows the RPM for both fans.
The nominal value is 5000 RPM for the Model 3005 and 3800 RPM for the Model 3015–3080, with an
acceptable minimum of 3000 RPM for both. Values below this minimum trigger a hardware event.

CPU, Cage

The VPN Concentrator Model 3015–3080 includes two temperature sensors on the main printed circuit
board: one near the CPU and one near the power supply cage. The Model 3005 has one sensor near the
CPU. This table shows the temperature at the sensor(s). Temperatures between 0° and 50°C (32° and
122°F) are acceptable. Values outside this range trigger a hardware event.

CPU Utilization

This usage graph shows the CPU load as a percentage of the maximum possible load. Each segment
represents 10% of the maximum possible load.

Active Sessions

This usage graph shows the number of active sessions as a percentage of the maximum possible sessions.
For example, if 5000 sessions is the maximum, each segment represents 500 sessions. The first segment
lights with the first session, the second lights with 10% plus one session, etc.

Throughput

This usage graph shows current throughput (measured in LAN packets) as a percentage of the maximum
possible system throughput. For example, if two interfaces are set for 100 Mbps, the maximum possible
throughput is 200 Mbps and each segment represents 20 Mbps.
