Learn Farsi: چنانچه پورت خراب باشد، روتر را ریست کنید. - In the event that the port is broken, reset the router.

The conjunction chenânche (in the event that) triggers a conditional clause. In Farsi, the condition part of an 'if' statement requires the present subjunctive (like bâshad) to indicate that the situation is a possibility rather than an established fact.

The lesson says we can use the simple past with chenânche. What would that look like in this sentence, and does it change the meaning?

You could write chenânche port xarâb bud, replacing the subjunctive bâshad with the simple past bud. In conditional sentences, the simple past can sometimes feel slightly more remote or less likely, but in practical instructions like this one, there is no real difference in meaning. Both mean 'if the port is broken'.

Is chenânche interchangeable with agar (if) here?

Grammatically, yes, you can swap it for agar and keep exactly the same sentence structure. However, chenânche is more formal and is frequently used in written instructions, manuals, or official contexts, which perfectly matches the technical vocabulary used here.

How do English tech words like 'reset' function grammatically in this sentence?

Farsi creates new verbs from English loanwords by pairing them with a 'light verb', most commonly kardan (to do). Here, 'to reset' is reset kardan. Because this is a command to the user, it is conjugated in the imperative plural or formal form as reset konid.
