Problem Symptoms

When an HSSI or X.21 cable is disconnected then reconnected to any of the active serial ports on the FRSM-HS1, the FRSM-HS1 may reset, which interrupts all data transmitted over that card for a short period of time. The reset is recorded in the AXIS Event log and on the HP Openview® Event Browser.

Solution

The fix for the FRSM-HS1 reset is in AXIS firmware 4.0.07. This firmware is available in CCO's Software Center (registered customers only) .

Workaround

Until firmware 4.0.07 is loaded, it is recommended that the following steps be taken if a cable needs to be moved from one FRSM-HS1 port to another:

  1. Delete the connections.

  2. Deactivate the port.

  3. Connect the cable to the new port.

  4. Activate the new port.

  5. Add the connections to the new port.
