Change default user names and passwords immediately
After installation and initial configuration of the Rack PDU, immediately change the
user names and passwords from their defaults to unique user names and passwords to
establish basic security.
Port assignments
If Telnet, the FTP server, SSH/SCP, or the Web server uses a non-standard port, a user
must specify the port in the command line or Web address used to access the Rack
PDU. A non-standard port number provides an additional level of security. The ports
are initially set at the standard “well known ports” for the protocols. To increase security,
reset the ports to any unused port numbers from 5001 to 32768 for the FTP server and
from 5000 to 32768 for the other protocols and servers. (The FTP server uses both the
specified port and the port one number lower than the specified port.)
User names, passwords, and community names with SNMPv1
All user names, passwords, and community names for SNMPv1 are transferred over
the network as plain text. A user who is capable of monitoring the network traffic can
determine the user names and passwords required to log on to the accounts of the
command line interface or Web interface of the Rack PDU. If your network requires the
higher security of the encryption-based options available for the command line
interface and Web interface, disable SNMPv1 access or set its access to
Read . ( Read
access allows you to receive status information and use SNMPv1 traps.)
To disable SNMPv1 access, on the Administration tab, select Network on the top
menu bar and access under the SNMPv1 heading on the left navigation menu. Clear
the Enable SNMPv1 access checkbox and click Apply .
To set SNMPv1 access to Read , on the Administration tab, select Network on the top
menu bar and access control under the SNMPv1 heading on the left navigation menu.
Then, for each configured Network Management System (NMS), click the community
names and set the access type to
Read .
