•
• IP default gateway
An ACL may be assigned that
denies entry.
Management interface IP
address or subnet mask is
incorrect.

Too many Telnet connections
(up to five concurrent
sessions are supported via
Telnet ).
Default gateway is incorrect
(when the host used as client
is not in the same network as
the SCE Platform).
