The power cables are specific to the power requirements of your country or region.
Attention: The power cord is the main power disconnect. Ensure that the socket
outlets are located near the equipment and are easily accessible.
TCP/IP requirements
To plan your installation, consider the TCP/IP address requirements of the system
and the requirements to access other services. You must also plan for the Ethernet
address allocation and for the configuration of the Ethernet router, gateway, and
firewall.
The following table shows the services and TCP/IP ports:
Table 7. TCP/IP ports and services listing
Service Traffic direction Protocol Port Service type
Email (SMTP) notification for Call Home and
inventory reporting
Outbound TCP 25 optional
SNMP event notification Outbound UDP 162 optional
Syslog event notification Outbound UDP 514 optional
IPv4 DHCP (Node service address) Outbound UDP 68 optional
IPv6 DHCP (Node service address) Outbound UDP 547 optional
Network time server (NTP) Outbound UDP 123 optional
SSH for command line interface (CLI) access Inbound TCP 22 mandatory
HTTPS for GUI access Inbound TCP 443 mandatory
Remote user authentication service - HTTP Outbound TCP 16310 optional

Directory Access Protocol (LDAP)
Outbound TCP 389 optional

Both IPv4 and IPv6 addresses are supported.
For configuration and management, you must allocate an IP address to the
Ethernet management port on each canister, which is referred to as the
management IP address. If both IPv4 and IPv6 are operating concurrently, an
address is required for each protocol.
You can configure the enclosure for event notification by SNMP, syslog, or email.
To configure notification, you must ensure that the SNMP agent, syslog IP
addresses, or SMTP email server IP addresses can be accessed from all
management addresses.
The system does not use name servers to locate other devices. You must supply the
numeric IP address of the device. To locate a device, the device must have a fixed
IP address.
Checking your web browser settings for the management GUI
To access the management GUI, you must ensure that your web browser is
supported and has the appropriate settings enabled.
