Firewall, Failover & Oob; Oob Dial-In Access - Tripp Lite B092-016 Owner's Manual

Chapter 5: Firewall, Failover and Out-of-Band
The Console Server has a number of failover and out-of-band access capabilities to ensure availability in the event there are
difficulties in accessing the Console Server through the principal network path. This chapter covers:
• Out-of-band (OoB) access from a remote location using dial-up modem
• Out-dial failover
• OoB access using an alternate broadband link
• Broadband failover
The Console Server can also provide basic routed firewall facilities with NAT (Network Address Translation), packet filtering and
port forwarding support on all network interfaces.

OoB Dial-In Access

To enable OoB dial-in access, first set up the Console Server configuration for dial-in PPP access. Once the Console Server is
so configured, it will wait for an incoming connection from a dial-in at a remote site.
Then remote Administrator's must be configured to dial-in and must establish a network connection to the Console Server.
Note: The B094-008-2E-M-F, B096-048/016 and BO095-003-M Console Servers have an internal modem for dial-up OoB
access. The B092-016 Console Server needs an external modem to be attached via a serial cable to its DB9 port. With the
B095-004 Console Server the four serial ports are by default all configured as RJ serial Console Server ports. However Port 1
can be configured to be the Local Console/Modem port for an external modem to be attached.
