DHCP (Dynamic Host Configuration Protocol)
DHCP is an Internet protocol used to automate the configuration of computers using TCP/IP.
DHCP can be used to do the following:
• Assign IP addresses automatically
• Deliver TCP/IP stack configuration parameters, such as the subnet mask and default router
• Provide other configuration information, such as printer addresses
Digital Certificate
A digital certificate is an attachment to an electronic message used for security purposes. The
most common use of a digital certificate is to verify that users sending a message are who they
claim to be, and to provide the receiver with the means to encode a reply.
An individual wishing to send an encrypted message applies for a digital certificate from a
Certificate Authority (CA). The CA issues an encrypted digital certificate containing the
applicant's public key and a variety of other identification information. The CA makes its own
public key readily available through print publicity or perhaps on the Internet.
The recipient of an encrypted message uses the CA's public key to decode the digital certificate
attached to the message, verifies it as issued by the CA and then obtains the sender's public key
and identification information held within the certificate. With this information, the recipient
can send an encrypted reply.
The most widely used standard for digital certificates is X.509.
DSR switch
The DSR switch is part of the Avocent digital KVM switch series of products that allows

DSRIQ module
A DSRIQ smart module uses CAT 5 cabling to attach a target device to a DS1800 digital
switch or DSR switch. The DSRIQ module significantly reduces cable bulk in the rack and is
well suited for high-density installations.
