We’ll start off with a disambiguation of all the terminology that gets thrown around when discussing physical cabling, then answer a couple basic questions: Why do we need crossover cables vs straight-through? What exactly is Twisted Pair? How is a single bit transmitted across the wire? Finally, we’ll wrap things up with a look at the standard for Gigabit Ethernet. But in light of our mission statement, we thought the topic of Ethernet Wiring deserved a bit more depth. Initially, this article was meant to just cover the basic differences and use-cases for Crossover cables and Straight-through cables. It also determines how to interpret those bits into meaningful frames. It describes how to send bits (1s and 0s) across each wire. Write this down somewhere as you will need to enter it as the reset password later.Ethernet is a family of specifications that governs a few different things: It covers all the different wiring specifications (10BASE-T, 100BASE-TX, 1000BASE-T, etc…). This will be a 12 digit number appearing on a sticker at the back of your phone.

Step 2: Polycom Factory Reset without Passwordįirst you will need to look at the back of your phone to locate the MAC address.

If this still does not work, we will go to the next step and perform a reset without the password. Enter the admin password ( 456 by default).Scroll to the Settings (gear icon) and click on it.To perform a factory reset with the default (or a known) password do the following: So before we get started, it’s worth trying to do a factory reset with the default password of 456 in case it was never changed. If you purchased a Polycom phone used, it was previously deployed in a network environment that you didn’t manage or was provided by another cloud provider, unfortunately it’s likely that the password was changed.
