Attaching to the serial port while the Fibre Channel hub is on
1. If the 3534 Managed Hub is on, you can attach your service terminal, login, and
run most diagnostics. However, you need to get an admin username and
password recognized by the Fibre Channel hub from the system administrator.
2. After you get an admin username, stop any Ethernet session active on the
Ethernet port.

administrator, as well as the hub IP address or name.
When you have the IP address, admin level username, and password, perform the
following steps:
1. Go to the server having LAN access and, in an open window, type:
Telnet IPaddress
or
name
(the hub IP address or name you were given by the
system administrator)
The hub responds:
login
2. Type the username you were given and press
Enter
.
The hub responds:
Ipaddress password:
3. Type the password you were given. The hub responds:
