Fast SwitcHub-8mi SNMP Advanced Reference Guide Configure the Remote Site: At the remote site, connect the PC's COM port (COM 1~4) to the modem's serial port. Set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, 9600 or 19200 bps and no flow control. If this is your first time to log into the configuration program, then the default passwords are still "admin" and "guest.
Fast SwitcHub-8mi SNMP Menu Port Configuration Description Advanced Reference Guide (continued) System Configuration Disables/enables any port; sets communication mode to autonegotiation, full duplex or half duplex; sets the aging time for entries in the address table, the processing scheme for forwarding packets to adaptive cut-through, cut-through, fragment-free cut-through, or storeand-forward; and enables/disables flow control.
Fast SwitcHub-8mi SNMP Advanced Reference Guide BOOTP - When BOOTP is selected, the switch repeats requests at regular intervals, until it receives a valid reply. The requests will cease if a valid IP address is configured or the IP state is set to IP Disabled.
Fast SwitcHub-8mi SNMP Advanced Reference Guide Changing System Passwords Parameter Description Use the Password Configuration screen to display and modify passwords for the onboard configuration program. There are two user types, "Administrator" and " Normal User," the access privilege is Read/Write for Administrator and Read Only for Normal User. The default passwords are "Admin" and "Guest."

Fast SwitcHub-8mi SNMP Communication Mode - If you use auto-negotiation, be sure the attached device also supports this mode. If any device attached to the switch runs at full duplex, but does not support auto-negotiation, you will need to manually set the communication mode to full duplex. However, once set, the communication mode setting will remain unchanged, even if the link is broken (e.g., by unplugging the cable, or by a power reset).

Fast SwitcHub-8mi SNMP Parameter Description Display Diagnostics While Power-On Diagnostic indicators can be enabled/disabled during a hard reset. Reset Unit with Diagnostics Resets the unit and runs diagnostics. Clears all counters and restores configuration parameters from nonvolatile memory. The full process requires about 30 seconds. Reset Unit without Diagnostics Resets the unit without running diagnostics. Clears all counters and restores configuration parameters from nonvolatile memory.
