Oracle Talari T5200 | Hardware Guide
Troubleshooting
The following section outlines some troubleshooting steps and guidelines for the T5200.
Basic Troubleshooting
The key to problem solving is to isolate the problem to a specific subsystem by comparing what
the appliance is doing to what it should be doing. The T5200 has LEDs and NIC indicators on the
rear panel for the indication of power, disk activity, Ethernet activity, etc. These indicators can
assist in isolating the problem to a specific subsystem.

Table 3: Troubleshooting Basics
Troubleshooting Bypass Mode (Fail-to-Wire)
The T5200 is equipped with a capability known as “bypass mode” or “fail-to-wire.” This
capability is designed to prevent a single point of failure. If there is a serious problem with
the Talari Appliance, the bypass pair enters bypass mode and forwards traffic through as
though the appliance were a wire.
A bypass pair may be configured as either “fail-to-wire” or “fail-to-block.” If a bypass pair
is configured for “fail-to-block,” bypass mode is not activated even if power is lost.
Bypass pairs are configured as “fail-to-wire” by default.
Bypass mode is used when the appliance is not powered on, when the Talari Appliance is
powered on but is not configured, or when the appliance is powered on and configured but
the Talari Service is disabled. When the T5200 is in bypass mode, one or both of the bypass
LEDs will stop blinking green.
