Can I connect to my IP KVM (AP5405) via an external modem?


Product Line

• Rack Accessories - IP KVM
  • AP5405 (discontinued)

Environment

• All serial numbers
• All firmware versions

Cause


With AP5405, in most cases, you will connect to your IP KVM via a local console (keyboard, monitor,mouse connected directly to the KVM) or over a remote network connection (IP via a web browser).

However, in some instances where remote access is needed, but your network connection has been lost, dial in access is required.


Resolution

The IP KVM (AP5405) provides this functionality. To connect to an IP KVM (AP5405) via a dial in connection, you must connect your remote modem to the Auxiliary port of the IP KVM.




Generally, it is advised that you use a remote modem that can be configured for speeds up to 115200, in order to provide a faster connection.

APC has tested the connection between the remote modem and the Auxiliary port using APC cable part number AP9308 (940-0215 is stamped on the cable itself).

Once you have connected your remote modem to the Auxiliary port, you have to configure the Auxiliary port for dial in access. You can find the configuration settings under Configuration/Aux Port of the web interface.

The following settings must configured to match the modem:

• Profile: PPP (Power Management will not work)
• Baud Rate, Flow Control, Parity, Stop Bits, Data Size: <User preference, but must match on the modem>
• Modem Initialization: <Generally, the default setting should work with most modems, reference your modem's user manual for further details>
• Local IP Address: <IP Address of the IP KVM>
• Remote IP Address: <IP Address to be assigned to your local workstation dialing to the IP KVM>
• Authentication Required: <Default>
• MTU/RTU: <Default
• PPP Options: <Generally, the default setting should work with most modems, reference your modem's user manual for further details>

Once you have configured the Auxiliary port, dial in access should be possible, as long as the modem is also configured properly.

When you dial in from your local workstation, you will establish a PPP connection, meaning your workstation will be assigned an IP address (the Remote IP Address as specified above) and the IP KVM will maintain its current IP. Once a connection has been established, you can open a web browser and enter the IP address of the IP KVM (the Local IP Address). The web login of the IP KVM should appear. Login as you normally would. Please remember that since you are establishing a dial in connection, your connection speed may be a lot slower than a connection over IP. This is a limitation of using a dial up connection and is not a problem with the IP KVM.
