# Preinstallation Requirements

Before installing SME, ensure that you do the following tasks:

• Install Java 1.5 or 1.6 on the DCNM-SAN.

• If you are using SSL, install OpenSSL on the server to be used for SSL certificate generation.

• Ensure that essential ports are allowed through the firewall and on the management interface.

• If you are using DNS, ensure that all switches and the KMC server, are mutually reachable (through the ping command) using their DNS names.

• Synchronize the time between all the switches, the KMC and the server used for generating SSL certificates. Configure NTP if required.

• Ensure that the hosts and the tape drives are appropriately zoned.

• Ensure that there is CLI access to the switches.

• Install smart card reader drivers.

• Ensure that the required number of smart cards and readers are available.

• Install the MSM-18/4 modules and SME licenses on the required set of switches.
