Connectivity
The ESX-1320 switch connects to the external Ethernet networks or
workstations through the 12 standard RJ45 connectors on its front panel.
The RJ45 connectors (interface ports) support Unshielded Twisted Pair
(UTP) and Shielded Twisted Pair (STP) cabling at lengths up to 100
meters. The ports are IEEE 802.3 10BASE-T compliant.
The ESX-1380 switch connects to the external Ethernet networks or
workstations through the 12 Fiber Optic ST connectors on its front panel.
The ports are Fiber Optic Inter-Repeater Link (FOIRL) compliant.
The ESX provides a port located on the front panel that supports one
Cabletron Systems Bridge/Router Interface Module (BRIM). BRIMs are
an optional feature for the ESX that provide flexible, integrated switching
functions to the workgroup and enterprise network hub. Refer to the
Release Notes
for a list of BRIMs currently supported by the ESX.
Memory
The ESX has 4 Megabytes (MB) of Shared Dynamic Random Access
Memory (SDRAM), 4 MB of Local Dynamic Random Access Memory
(LDRAM), and 2 MB of FLASH Electrically Erasable Programmable
Read Only Memory (FLASH EEPROM). A new firmware image can also
be loaded while the system is operating through a Runtime Download.
This option allows the loading of a new firmware image from a network
interface into FLASH memory while the ESX is operating with the “old”
image. In addition, the ESX motherboard provides the option of
upgrading memory capacity by using Single In-line Memory Modules
(SIMMs). Cabletron Systems currently offers an 8 MB upgrade for
LDRAM and SDRAM (Part Number 8MB-SCM-UGK-60). Note that the
SDRAM is used for packet processing; the LDRAM is used for statistical
information and RMON support.
Full Duplex Switched Ethernet (FDSE)
Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in FDSE mode. FDSE
allows each port to provide a dedicated 20 Mbps bandwidth for file server
or high-end workstation connections.
