Different input current values of a device obtained in different tests

26

A current value change indicates a power consumption change, which may occur when the fan rotating speed is intelligently controlled. If the device voltage is normal and the device is normally operating, no abnormality occurs even though the device current values are changing.

Why is the actual suppression value different from the configured traffic suppression value
The traffic suppression supported by AR series routers is a type of granularity-based suppression. -The AR1200 series use the committed information rate (CIR) mode. If the traffic suppression value is between 64 kbit/s and 1000 kbit/s, the granularity is 64 kbit/s. For example, if the traffic suppression value is set to 65 kbit/s, the effective traffic suppression value is 64 kbit/s. If the traffic suppression value is set to 200 kbit/s, the effective traffic suppression value is 128 kbit/s, and so on. If the traffic suppression value is between 1000 kbit/s and 100,000 kbit/s, the granularity is 1000 kbit/s. For example, if the traffic suppression value is set to 1001 kbit/s, the effective traffic suppression value is 1000 kbit/s. If the traffic suppression value is set to 2999 kbit/s, the effective traffic suppression value is 2000 kbit/s, and so on. -The AR2200 , AR3200 and AR3600 series use the packet mode. The granularity is 125 packets per second (pps). If the traffic suppression value is set to 10 pps, the effective traffic suppression value is 0 pps. If the traffic suppression value is set to 126 pps, the effective traffic suppression value is 125 pps, and so on. Therefore, if the traffic suppression value is not set to a multiple of the granularity, the actual suppression value is different from the traffic suppression value that is set. Within a specified granularity range, all suppression values are correct.

What is the input current for an S series switch
If an S series switch uses pluggable power supplies, view the silkscreen of input current on power sockets. If a switch uses built-in power supplies, you can also view the silkscreen on the power sockets.

Why different clients obtain the same IP address
When an S series switch functions as a DHCP server, a DHCP client accesses the network again in the following process: The DHCP client broadcasts a DHCP Request packet carrying the IP address allocated in the first time, that is, the Option 50 field in the packet. After receiving the DHCP Request packet, the DHCP server checks whether the lease record exists based on the MAC address in the packet. If so, the DHCP server replies with a DHCP ACK packet to notify the DHCP client that the requested IP address can be used. If not, the DHCP server waits for a new DHCP Discover message from the client.
