for all ports
1

High uplink/stacking bandwidth

4 10GE SFP+
ports provide up to 40G bandwidth. It provides high flexibility for physical
stacking or uplink application use.

Enlarge MAC address table to
32K

(DGS
-
3600 series is 16K)

Smart Fan

Power saving: Internal heat sensor monitors switch’s temperature and adjusts the fan speed
accordingly.

Improve the MTBF with slower fan speed and reduce the noise
2

External SD Card

Easy to store and restore file with portable SD card (like FW, configuration file, boot image,
syslog or other files).



External Alarm Port
3

Provides digital I/O design on external alarm port. It can provide better security protection.

With digital in, DGS
-
3620 can receive events detected by external sensors (eg. temperature,
smoking or anti
-
theft sensor). The switch can send a trap/log out to report the issue.

With digital out, DGS
-
3620 can activate external air
-
conditioner/fan or ring the bell based on
the condition customer defined.

MPLS


MPLS
*

provides the “Best
-
effort Delivery

. It speeds up the data delivery,
improves the packet QoS and solves the burden of IP routing

MPLS adopted the core idea of ATM. It locates itself between IP layer and
data link layer and takes the responsibility of carrying any traffic over itself

What MPLS learns from ATM:


Thinking of label switching


Using Local Label instead of global IP address


Note: DGS
-
3620 will support MPLS in the future
