Telnet and SSH

You can access the control console through Telnet

or Secure SHell (SSH), depending on which is

enabled. (On the Administration tab, select

Network on the top menu bar and select Access

under the Console heading on the left navigation

menu to enable these access methods.) By default,

Telnet is enabled. Enabling SSH automatically

disables Telnet.

Telnet for basic access. Telnet provides the

basic security of authentication by user name and

password, but not the high-security benefits of

encryption. To use Telnet to access a

PDU control

console from any computer on the same subnet:

1. At a command prompt, use the following

command line, and press

ENTER:

telnet address

As address, use the

PDU’s IP address or

DNS name (if configured).

2. Enter the user name and password (by default,

apc and apc for an Administrator, or device

and apc for a Device Manager).

SSH for high-security access. If you use the

high security of SSL for the Web interface, use

Secure SHell (SSH) for access to the control

console. SSH encrypts user names, passwords, and

transmitted data.

The interface, user accounts, and user access rights

are the same whether you access the control

console through SSH or Telnet, but to use SSH,

you must first configure SSH and have an SSH

client program installed on your computer.

SNMP

After you add the PowerNet MIB to a standard

SNMP MIB browser, you can use that browser for

SNMP access to the

PDU. The default read

community name is public; the default read/write

community name is private.

To use InfraStruXure Manager to manage a

PDU

on the public network of an InfraStruXure system,

you must have SNMP enabled in the

PDU

interface.

To enable or disable SNMP access, you must be an

Administrator. Select the Administrator tab,

select the Network menu on the top menu bar, and

use the access option under SNMP on the left

navigation menu.

information on configuring and using

SSH.
