Possible Cause
Management interface IP
address or subnet mask is
incorrect.
Telnet server is disabled.
Too many Telnet
connections (up to 5
concurrent sessions are
supported).
Default gateway is incorrect
(when the host used as client
is not in the same network as
the SCE Platform).
Routing tables are
incorrectly configured
(when the host used as client
is not in the same network as
the SCE Platform, and there
is more than one gateway on
the SCE Platform network).
Host is not a member of a
valid access-list.
Telnet connection may be
timing out.
