Ethernet Interfaces
The 7210 SAS-D provides 6 100/1000 SFP ports. Each port can be used for a direct connection to 
a subscriber’s Customer Premises Equipment (CPE), or as an uplink to another aggregation node. 
The 7210 SAS-D also provides 4 10/100/1000Base-T fixed copper ports.
Console Port 
The console port uses an RJ-45 connector with serial pinouts (see Table 11) that enables a 
connection to a terminal for performing switch monitoring and configuration operations. The 
terminal may be a PC or workstation that is running terminal emulation software, or a terminal 
configured as a Data Terminal Equipment (DTE) connection. A null-modem wired serial cable is 
supplied with the switch for connecting to this interface. 
The serial port configuration requirements are as follows: 
• Default Baud rate – 115200 bps 
• Character Size – 8 Characters 
• Parity – None 
• Stop bit – One 
• Data bits – 8 
• Flow control – none 
Alarms
When your system has a major alarm, the CPU will turn the status LED amber. Currently, the 
system provides an alarm for the following event:
• Chassis temperature threshold exceeded - Major alarm is raised.
Air Ventilation
7210 SAS-D does not have fan. Operators must allow for at least three inches of clearance on all 
sides of the device to ensure proper airflow intake cooling system.
