How to Prevent System Breakdown or Service Interruption of the MA5600 Caused by Network Attacks Through the Proper Configuration

The common improper configurations that affect the system security are as follows:
The ring network detection function and the anti-MAC address-spoofing function or anti-IP address-spoofing function are disabled. When the anti-MAC address-spoofing function or the anti-IP address-spoofing function is disabled, the ******* user sends the PPPoE and DHCP control packets by forging the MAC address or IP address of a legal user. In this case, the security of the system is affected.
Huawei MA5600
Run the ring check command to enable the ring network detection function on the user side
Run the security anti-macspoofing enable command to enable the anti-MAC address-spoofing function.
Run the security anti-ipspoofing enable command to enable the anti-IP address-spoofing function
The devices are managed by IP addresses of the public network and the access rights are not limited strictly when the ACL rule is configured. In this case, the network is attacked.
To ensure the security of devices, manage the devices by using the IP addresses of the private network. When configuring the ACL rule, you must comply with the principle of the minimum authorization to configure the accessible address segment. The accessible address segment can contain only the mandatory IP addresses of the management network segment. Other IP addresses cannot access the device management interface.
Run the acl command to create a basic ACL and enter the ACL mode. The number of a basic ACL can only be in the range of 2000-2999.
In the basic ACL mode, run the rule command to create a basic ACL rule. The parameters are as follows:
rule-id: Indicates the ACL rule ID. To create an ACL rule with a specified ID, use this parameter.
permit: Indicates the keyword for allowing the data packets that meet the related conditions to pass.
deny: Indicates the keyword for discarding the data packets that meet the related conditions.
time-range: Indicates the keyword of the time range during which the ACL rule is effective.
The packets that access the device management interface are not controlled so that the device is attacked by the packets. In this case, the system is caused to be busy and the services are affected.
Run the firewall packet-filter command to apply the packet filtering rules of the firewall to the interface to filter the packets that access the interface. In this case, the packet attack is prevented.

IP configuration

You can set three IP parameters from the printer control panel. The available parameters are:
  • IP Address
  • Subnet Mask
  • Gateway (optional)
The procedure for changing any of the parameters is the same. The procedure for changing the IP Address is given here as an example. Use the same procedure for the other IP parameters.
  1. Make sure the printer is on and paper/ribbon is loaded.
  2. Press the PAUSE key to place the printer in the OFFLINE mode.
  3. Unlock the Front Panel. (DOWN Arrow + ENTER keys at the same time.)
  4. Press the MENU key until the LCD displays "ETHERNET ADDRESS."
  5. Press the DOWN arrow key to access the first segment of the IP address to be changed. (Or press DOWN arrow again to scroll through the Subnet and Gateway segments.)
  6. Press the + (plus) or - (minus) keys to change the segment.
  7. Press ENTER to make the selection. An asterisk appears to the right of the value.
  8. If other IP address segments need to be changed, go to step 5.
  9. When Finished the [Pause] key twice to go ONLINE. This burns the IP information into the printer.
The ethernet configuration is global to the printer, and takes effect immediately.

When I turn the copier on: Error code E000 appears and it turns off automatically. What's wrong?

e000 means the machine not sensing the heat by his thermistor within a presetted period in "FIXING UNIT"

check heaters lamp in upper heat roller in fixing unit.
check thermostate and clean/replace thermister.

A E000, means that the fuser is not warming up correctly. You can try to unplug the copier and see if it will reset. If it will not reset, you will have to have the fuser unit replaced or the upper fuser heater unit and film. Good Luck

ERROR 0175: Bad CRC1, stop POST task message Been using my IBM a30 laptop for some months but was surprised to get this error when i tried putting it on this message pops up ERROR 0175:BAD CRC1 STOP POST...

You obviously didn't read the problem carefully. The machine won't boot, so there is no command line. I have the same problem with a T23. It might be the CMOS battery that needs to be replaced.

Error E000

First of all a E000 is a power proble that the fuser is not warming up in time or power is not avaible. Is it possible that you may not have a outlet just for the copier by it self.... It could be low on usable power. If the power is good, I would say that your Upper heating unit is shorting out from time to time. You will need to have to replace the fixing unit if it is to much of a pain to deal with.
