    How to change the IOS directory when a 3750 boot-up?

    Hello- I've upgraded my switch firmware from IPBase to IPSevices. The download works well but upon boot-up, it will look for the old IOS first and display this error: Error loading "flash:/c3750-ipbasek9-mz.122-50.SE5/c3750-ipbasek9-mz.122-50.SE5. bin" It will still load using the new IOS...

    Hi- I canceled my maintenance agreement with Avaya and switch to a local provider with a lower monthly cost. I didn't notice this initially after the switch (maybe after a month or so) but for some reasons, some of my admin commands such as busyout or release trunks are no longer there. I...

    When to use a 120 A CSU on a TN464?

    Hi- Just a bit confused: when do you need to use a 120A CSU on a TN464F? I have noticed on this client Prologic that for some, they have their TN464s connected to a 120A CSU but some do not. I was thinking that they have an external CSU/DSU but none. Any ideas? Those with 120A are connected to...

    How to get my own IP block?

    Hi- I'm sure somebody here has done this before. We're a start-up company but we get tired of changing our IP adds each time we replace our Internet provider. Any ideas where to start? We're also thinking of getting our own ASN from ARIN. Thanks.
