The remote computer interfaces ARCNET and Ethernet BSD socket do not require any passwords before issuing commands although in both cases the user s control program must supply a port address when a sending command message Edit and View Remote Human Interface Modes The EDIT and VIEW commands are intended to provide some degree of settings security for the remote human interfaces RS 232 Telnet and FTP When the a mainframe is in view mode commands from all remote human interfaces which might change settable values or cause HV generation to be started are inhibited After a remote human interface command session has been initiated the VIEW command can be used to activate view mode The EDIT command can be used to de activate view mode If passwords are enabled a four digit number password can be established with the PASSWORD command In which case the VIEW and EDIT commands must always be followed by this four digit password Also once a password has been set following command sessions always begin in the view mode To change settings or initiate HV generation in a view mode session with passwords enabled the EDIT command must be issued with the four digit password Password protection can be disabled Factory Default by changing the mainframe s system defaults via the 1454 front panel VT100 display SYSTEM menu by selecting System Defaults When password protection is enabled no password is active until set

4. More efficient mainframe firmware initialization decreases the unit power up time by more than 50 and also reduces processing time for restore recall operations Previous versions allowed local front panel save recall operations while in remote or when values were locked Now local save and recall operations can only be done if the front panel switch is in the local position and the values are not locked The number of values returned by the ID command is no longer restricted to a fixed number Their are currently 10 fields defined in the command response Future module types may require additional fields Once an RS 232 session has begun sending a space followed by carriage return in previous versions caused the mainframe to beep pause then beep and eventually return the prompt with a 5 second delay This feature has been removed Now the session prompt is returned without beeps or delay The serial VT100 command is not accepted with the front panel switch is in LOCAL After a the V T100 full screen mode is activated switching the front panel switch to LOCAL terminates this display mode Previous versions did not properly handle modules with more than 1 submodule like the 1469 Ext Serial HW can sometimes fail to transmit characters while at the same time receiving characters Mainframe firmware driver changed to correct this condition Changes Since V2 36 1454 V2 51 1458 New hardware for handling module communication dec
5. Network switches gateways maintain tables of network port vs IP address in order to route network messages These tables if not dynamically updated can prevent messages from being routed to a new location Beware that even though an HV mainframe may respond to ping you may not be able to access it via Telnet or the other application protocols if the controlling host is on a different subnet from the mainframe and the subnet s gateway system does not support proxy ARPs In which case you should make sure that the HV mainframe s gateway IP address and subnet mask is properly set TELNET After verifying that the remote HV mainframe responds to a ping and as needed configuring the mainframe s gateway IP address and subnet mask use your host s Telnet utility to transmit HV commands in same manner as from a serial terminal Start your Telnet session with local echo enabled and enter the network password to the prompt The default network password is Irs1450 See the discussion about the NETPASS command in the section on HV commands on how to change this password Although the Telnet protocol is enabled as a factory default it is possible that a previous user of a mainframe may have disabled the Telnet port Use the ENET command or for a 1454 the ETHERNET SETUP submenu to assure that this protocol is enabled Remember to cycle the mainframes power after any changes Shown below is a typical Telnet session where the us
