ELTEX MES53xx User Manual

MES53xx, MES33xx, MES23xx Ethernet Switch Series 8
2 PRODUCT DESCRIPTION
2.1 Purpose
High-performance aggregation switches MES5324 and MES3324 have 10GBASE-X, 40GBASE-X ports
and are designed to be used in carrier networks as aggregation devices and in data processing centres as
top-of-rack or end-of-row switches.
The ports support 40 Gbps (QSFP) (MES5324), 10 Gbps (SFP+) or 1 Gbps (1000BASE-X and
1000BASE-T SFP) for higher flexibility and ensure that you can gradually move to higher transfer rates.
Non-blocking switch fabric ensures correct packet processing with minimal and predictable latency at
maximum load for all types of traffic.
Front-to-back ventilation ensures efficient cooling in data processing centres.
Redundancy fans and AC or DC power supplies along with a comprehensive hardware monitoring
system ensure high reliability. The devices allow hot swapping of power and ventilation modules providing
smooth network operation.
MES2324 and MES2348 series access switches are L2+ managed switches with 24-
48x10/100/1000Base-T ports and 4x10GBase-X (SFP+)/1000Base-X (SFP) ports.
MES2308 access switches include 10x10/100/1000Base-T ports, (MES2308P – 8x10/100/1000Base-T
ports supporting PoE+, and 2x10/100/1000Base-T ports), 2x1000Base-X (SFP) ports.
The switches provide end users with connection to SMB networks and carrier networks through the
Gigabit Ethernet interface.
2.2 Switch Features
2.2.1 Basic Features
Table 2.1 lists the basic administrable features of the devices of this series.
Table 2.1. Basic features of the device
Head-of-Line blocking
(HOL)
HOL blocking occurs when device output ports are overloaded with traffic coming
from input ports. It may lead to data transfer delays and packet loss.
Jumbo frames
Enables jumbo frame transmission to minimize the amount of transmitted
packets. This reduces overhead, processing time and interruptions.
Flow control
(IEEE 802.3X)
With flow control you can interconnect low-speed and high-speed devices. To
avoid buffer overrun, the low-speed device can send PAUSE packets that will force
the high-speed device to pause packet transmission.
Operation in device
stack
You can combine multiple switches in a stack. In this case, switches are considered
as a single device with shared settings. There are two stack topologies—ring and
chain. All port parameters of each stack unit can be configured from the master
switch. Device stacking allows for reducing network management efforts.
2.2.2 MAC address processing features
Table 2.2 lists MAC address processing features.
