4.3 Ethernet Access: Telnet and SNMP Protocols
The optional 10/100 BaseT Ethernet port provides Telnet- or SNMP-based monitoring and management.
The 10/100 Base T Ethernet management services
card provides Telnet-based monitoring and
management, including firmware update using
FTP.
Remote system monitoring is also available using
Simple Network Management Protocol (SNMP).
An agent resides in the Diamond-VT which takes
information from the Array and translates it into a
form compatible with SNMP. If certain conditions
arise, the agent sends asynchronous notifications
(traps) to a client.
To connect to the Ethernet port
1
Connect a cross-over cable (for a direct
connection to a PC) or regular network cable
from a network device to the optional RJ45
Ethernet port on the Ethernet management
card on the front of the Diamond-VT.
2
If using a direct connection, power on and boot
up the host computer.
3
Attach a DB-9 null modem serial cable (the
cable must be no longer than three meters)
from the RS-232 port of the Diamond Array to a
host computer and open a terminal emulator
program on the host to set the Ethernet
parameters.Turn on the Diamond-VT.
4
First time use: Upon successful power up and
diagnostics, set the host computer with the
appropriate settings.
The host computer must have appropriate
network settings to allow it to communicate with
the Diamond-VT. Please see your system
administrator for more information.
To use Telnet
1
If you have not already done so, change the IP
address from the default by first accessing the
serial connection and using the CLI.
You may change the IP address to a network
specific value or, if the local network uses
DHCP, you may enable automatic IP
addressing (set IPDHCP enabled) using the
CLI.
2
Open a Telnet session on the host computer.

• IP address
• Port type: telnet
• Terminal type: vt100
3
If you make any changes to the network setting
on the Diamond Array, use the
SaveConfiguration Restart command.
4
Username/password: You are prompted for a
username and password, up to eight characters
each, case insensitive. Only one
username/password combination is available
per Diamond-VT.
• You may change the telnet username and/or
password after entering a CLI session using
the commands
set TelnetUsername [username]
set TelnetPassword [password]
• Or you may change the telnet username
and/or password using the Configuration
page of the ExpressNAV interface.
• The default username is telnet and default
password is diamond

In the Command Line Interface mode, see a list
of available commands by typing help at the
Ready prompt or refer to
Commands
on page 29.
6
Using the ExpressNAV interface, configure the
unit as RAID Level 10 or RAID Level 5 with
zones and/or Hot Spare sleds as described
later in the manual.
To use SNMP
1
Enter the Command Line Interface through the
serial port or Ethernet.
2
Change the IP address to a network specific
value or, if the local network uses DHCP,
enable automatic IP addressing.
3
Set the number of trap client addresses by
typing set SNMPTrapAddress [1-6]
[IPAddress] [Level]
4
Type set SNMPUpdates enabled.
5
Type set SNMPTraps enabled.
6
Type SaveConfiguration restart to reboot the
Diamond-VT.
7
Install SNMP management software on each
client you wish to receive traps (messages).
