Resetting the EMU
If your HP-authorized service representative instructs you to reset the EMU:
1. Firmly grasp the EMU mounting handle and pull the EMU partially out of the enclosure.
CAUTION:
Do not remove the EMU from the enclosure. You must avoid putting any strain on the cables
or connectors.
2. Wait 30 seconds, and then push the EMU in until it is fully seated in the backplane. The EMU
should display any enclosure condition report within two minutes.
Transceiver error conditions
The format of a transceiver condition report is 0.F.en.ec, where:
• 0.F. identifies a transceiver error.
• en. identifies which transceiver is affected (see Figure 37 ).
• ec is the error code.
