4.12.3 Degraded Mode Operations
If a BD BACTEC FX instrument loses communication with the BD FX master database, a
system
alert 30 is generated and the instrument enters a degraded mode of operation. In degraded
mode, only the following operations can be performed:
• Remove positive vials (but not related vials)
• Remove negative vials (not batch removal)
• Opening a drawer causes only the Positive (including Positive Anonymous) and Negative
stations to illuminate
• View System Alerts (not print)
• View Status and Drawer View displays
• Vials continue incubation, agitation, testing, and determination of results
• Instrument continues to monitor its state of health and generate applicable alerts
• Enter anonymous vials
• Maintenance functions except changing password, QC Report print
You cannot perform the following operations:
• Enter vials with Vial Entry
• Remove or view related vials
• View Culture displays
• Access Vial display by selecting a station in Drawer View display
• View vial plots
• Identify Anonymous vials
• Print reports
• Change passwords
• Adjust Configuration settings
Avoid moving vials in instruments that are in degraded mode. Avoid placing vials in degraded mode
instruments unless it is the only instrument with available stations.
Culture displays showing information on related vials that reside in a degraded mode instrument are
flagged with an offline indicator. No modifications can be made to these vials in the Specimen or Vial
tab.
When communications are reestablished, the instrument and its master database are reconciled and
the instrument resynchronizes with BD EpiCenter, updating any changes that have occurred at each
system. This includes statuses for sequenced vials, instrument status, and test readings. When the
reconciliation is complete, operations that were disabled (e.g., Vial Entry, Identify Anonymous) become
enabled again.
