Maintenance and Management Features
• Access Control
You can specify the service(s) and computer IP address(es) to control access to the switch
for management.
• Cluster Management
Cluster management (also known as iStacking) allows you to manage switches through
one switch, called the cluster manager. The switches must be directly connected and be in
the same VLAN group so as to be able to communicate with one another.
• Configuration and Firmware Maintenance
You can backup or restore the switch configuration or upgrade the firmware on the
switch.
1.3 Hardware Features
This section describes the ports on the switch.
Mini-GBIC Slots
Install SPF transceivers in these slots to connect to other Ethernet switches at longer distances
than the Ethernet port.
Gigabit Ethernet Ports
The ports allow the switch to connect to another WAN switch or daisy-chain to other switches.
Management Port
Connect a computer to this port for management purposes. You cannot access the network
through this port.
Console Port
Use the console port for local management of the switch.
Backup Power Supply Port
Connect a backup power supply device to this port to ensure uninterrupted network connection
in the event of a power failure.
Fans
The fans cool the switch sufficiently to allow reliable operation of the switch in even poorly
ventilated rooms or basements.
