Features

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.
