Standardize the six-step method
THINKMO
Type 1: Check the equipment
Does the model/serial number match?
Is the firmware version up to date?
Is the configuration backup saved?
Type 2: Look at the lights
The lights speak!
Red: Kombat 120! The device needs to be hung!
Yellow: It may just be coming to the aunt
Green: Don't be too happy, read the log!
The third formula: temperature measurement
The equipment will also have three highs!
Temperature>30°C? It's time to clean up! (Don't blow with your mouth!) ）
Humidity <</b30> 30%? Beware of static electricity!
Temperature and humidity: 22±2°C/40%-60%RH
Power supply ripple > 5%? Get ready to change the power supply!
Mains quality: voltage fluctuation ≤±5%, THD＜3%
Precision air conditioning outlet temperature difference detection (>7°C needs to be warned).
The fourth type: check the hardware
Power module: Dual input voltage difference <</b31>2V
Fan speed: 15% deviation from the benchmark value, report for repair immediately
Hard disk status: The SMART parameter focuses on 05/C5/C6
Type 5: Check the cable
Crystal head oxidation? Take an alcohol swab to wipe it? If you really can't do it, let's make a network cable again!
How > cable bend 90 degrees? Beware of gigabit to hundred!
Type 6: Check security
Login log review (focusing on 3AM-5AM operation records).
Privileged account login track traceability
The ultimate meaning: keep your hands behind
THINKMO
A set of cold and hot standby (both U disk and network disk are saved).
Configuration changes must be recorded (accurate to the second).
The emergency plan is posted on the wall (don't wait for the network to be disconnected and turn over the phone).
