I'm sorry to hear about your office flood and the equipment challenges you're facing. To proceed with equipment donations, you can try the following steps:
Contact TechSoup Directly: Reach out to TechSoup via their support channels to inquire about the specific equipment you need. They might be able to guide you on the availability or alternative solutions.
General Cisco Support: Contact Cisco's general support line or email. While they primarily handle technical issues, they might be able to guide you to the appropriate department for donations.
Local Cisco Partner: If applicable, contact a local Cisco partner or reseller. They may have information on donation programs or direct you to the right contacts.
I hope one of these avenues leads you to the assistance you need. Best of luck in resolving your situation.
