This chapter includes these sections:
◆“Overview” on page 11
◆“Key Technical Specifications” on page 15
Overview
The ECS4620-28T, ECS4620-28T-DC, ECS4620-28P, ECS4620-52T, and ECS4620-52P
are Gigabit Ethernet Layer 3 stackable switches with 24/48 10/100/1000BASE-T
ports, two 10-Gigabit (10G) Small Form Factor Pluggable Plus (SFP+) transceiver
slots. The ECS4620-28F and ECS4620-28F-DC are Layer 3 switches that provid 22
SFP 1G transceiver slots, two combination Gigabit RJ-45/SFP ports, and two 10G
SFP+ slots. The ECS4620-28P and ECS4620-52P front-panel ports also support
Power-over-Ethernet Plus (PoE+).
All switches also provide one rear-panel slot for a dual-port 10G hot-swappable
expansion module.
The switches include an SNMP-based management agent, which provides both in-
band and out-of-band access for managing the switch. Further, the switches
support both web and CLI-based configuration.
These switches include built-in stacking ports that enable units to be connected
together through a 40 Gbps stack backplane. The switch stack can be managed
from a master unit using a single IP address.
Power-over-Ethernet All of the 10/100/1000 Mbps ports on the ECS4620-28P and ECS4620-52P support
the IEEE 802.3at Power-over-Ethernet Plus (PoE+) standard that enables DC power
to be supplied to attached devices using wires in the connecting Ethernet cable.

Verify Switch Operation
Verify basic switch operation by checking the system LEDs.
When operating normally, the Power and Diag LEDs should both be on green. If
either of these LEDs are on amber, see “Diagnosing LED Indicators” on page 55.
Go to the section “Understanding the System Status LEDs” on page 51.
Figure 6: System LEDs
Make Initial Configuration Changes
At this point, you may need to make a few basic switch configuration changes
before connecting to the network. It is suggested to connect to the switch console
port to perform this task.
The serial port’s configuration requirements are as follows: 115200 bps, 8
characters, no parity, one stop bit, 8 data bits, and no flow control.
You can log in to the command-line interface (CLI) using default settings: User
“admin” with the password “admin”.
