telnet into a netgear switch?

Hey all, last night while at the datacenter I was in a pinch to extend a rack's LAN. I compromised and ran out to the local Fry's to buy whatever switch I could find so as to allow some configuration to happen while we wait for the real network gear to show up. I left before confirming I could access the switch remotely; it was very late and I was pretty groggy and hey, any network gear has to be telnet'table this day and age. Of course I was mostly wrong. The switch expects some signed payload before allowing a telnet through. I found this: https://code.google.com/p/netgear-telnetenable/...but I'm having a hell of a time getting anything to respond. The most confounding part is the switch doesn't respond to a single SYN packet on low ports. I'm scanning all the ports now, but if nothing shows up, I'm not sure what a payload is good for if the switch doesn't ACK a single SYN. I'm curious if anybody's got any tips besides not using Netgear in the datacenter. I have the MAC, I've IP'd it via DHCP, and the model number: JGS524E and I can power cycle the switch as much as needed. P.S. long time listener, first time caller. i'm more of a sysadmin dangerously standing in for a proper network person.
