"Err 14 Bad Password" on panel login to matrix
Likely cause: Err 14 is an authentication failure; the card rejects the panel because the stored password does not match.
- Step-by-step fixGet the fix →
"Err 4:3 Media Busy" — panel will not come online
Likely cause: Err 4:3 flags an IP/media conflict — the audio path cannot open because the address is already in use or invalid.
- Step-by-step fixGet the fix →
"Err 6:17"/"Err 6:18 Remote end busy" or "Err 6:19 Remote party unavail."
Likely cause: The 6:xx family indicates a networking/config problem after the card is reachable — busy card, saturated link, or blocked route.
- Step-by-step fixGet the fix →
"IVC Server not found" on the panel
Likely cause: The panel cannot locate the matrix card at the address it was given — a typo or wrong subnet.

How to upgrade a V-Series Iris / IrisX panel by USB
Likely cause: The panel's bootloader looks for a fixed filename (IRIS.ccf/IRIS.gz) at the USB root; a single device avoids the loader picking the wrong drive.

Intermittent IP drops or network loops; IVC/AES67 addressing rules
Likely cause: The two LAN ports are bridged unless configured for redundancy; looping them creates a broadcast storm.
- Step-by-step fixGet the fix →
IP panel is rejected / locked out after a config change (IP Port Lockdown / IP Security)
Likely cause: IP Security locks the card to known panel addresses; disabling it and re-applying the map clears the lockdown so panels can re-register.
- Step-by-step fixGet the fix →
No audio in or out after a firmware/software update (V-Iris panel)
Likely cause: The panel firmware and the FPGA are programmed in stages; pulling power mid-FPGA-write corrupts it, which kills the audio path even though the panel boots.
- Step-by-step fixGet the fix →
No mic audio / choosing dynamic vs electret mic
Likely cause: A dynamic mic on an electret setting (or vice-versa) gets the wrong bias/gain and reads as silent; the select button and mute are the other two common causes.
- Step-by-step fixGet the fix →
Panel is dead / will not power up — power spec and checks
Likely cause: The panel has no internal mains supply; nearly all "no power" cases are the external brick, its mains lead, or an unseated DC barrel.
- Step-by-step fixGet the fix →
Panel shows: Login user "<name>" denied
Likely cause: The matrix maps a panel to a port by user name; if the name does not match a configured port it refuses the login.

Panel stuck at "Connecting" then "Err 21 Remote offline" (or "Err 6:21 Remote offline") when logging into an IVC-32 / E-IPA
Likely cause: Err 21 / 6:21 mean the network is up but the target card did not answer — almost always a wrong connection mode or an unreachable/mistyped server IP.
