## Operating hints and warnings
|
||||
|
||||
* 😡 **Always** use grounding strap during dis/assembly or other cards' physical operation
|
||||
* 😡 **Always** power off devices before un/plugging
|
||||
* 🧐 If needed to power-cycle the crate, wait at least 30 seconds before turning them on
|
||||
* 🙅 Avoid the boards touching conductive materials - wires, metals. Use at
|
||||
least plastic ESD bags if you need the cards to be put at the desk or any other surface.
|
||||
* 💁 Be gentle to the EEM ports and any other connectors. Support them when plugging, hold when unplugging
|
||||
* 🙆 If you need to take the cards out, take them out one-by-one from the end, unplug EEM and cables if you feel high tension
|
||||
* 🙆 Use dedicated power supplies for each crate

2. Check that respective pins have voltages as described by `artiq_sinara_test`

3. If there are [BNC/SMA-IDC adapters](./bnc_sma_idc_adapter.md), also check their voltages - they should be the same

## Common problems
|

|
||||
### High-freq audible noise and output values all near -0.1 on Zotino v1.4.2
|
||||
|
||||
This may happen when power-cycle is too short. Power down the crate, wait at least 30 seconds, and power up again.
