Introduction
- The DELHG-UA and DELHL-UA are Gigabit Ethernet modular
interfaces, each of which provide a single Gigabit Ethernet connection that
fully conforms to the IEEE P802.3z (D3.1) Draft Standard. The
DELHG-UA
provides a single 1000Base-SX (short-wave) multimode fiber
optic SC interface, allowing for link distances of up to 500 meters. The
DELHL-UA
provides a single 1000Base-LX (long-wave) single
mode/multimode fiber optic SC interface, allowing for link distances of
up to 3 kilometers.
• The DLE28-MA module provides 24 fixed Ethernet multi-mode fiber ports via
ST connectors, plus a single slot for a modular interface.
• The DLE49-MA module provides 48 switched Ethernet ports via four RJ21
Telco connectors and a single modular interface slot.
• The DLE02-MA and DLE52-MA modules are 10/100 Fast Ethernet modules.
The DLE02-MA provides 24 ports via RJ45 connections. The DLE52-MA
provides 16 ports via RJ45 connections as well as a next-generation modular
interface slot, which can accept any of the previously detailed modular
interfaces, or the new DELVM-UA Gigabit Ethernet modular interface:
- The DELVM-UA is a Gigabit Ethernet module which provides two slots
for Gigabit Ethernet port interface modules of various media to offer
integrated Gigabit Ethernet uplink capability. The DELVM-UA can accept
the DELG1-UA, which offers one SC connector for MMF 1000Base SX
Gigabit Ethernet connectivity, the DELG9-UA, which offers one SC
connector for MMF or SMF 1000Base LX connectivity, or the DELG4-UA,
which offers one ANSI Fibrechannel style-2 connector for 150 Ohm STP
1000Base CX connectivity.
• The DLEHF-MA carrier module provides two Fast Ethernet port interface
module slots and two modular interface slots.
Each of these modules provide key mission-critical features such as redundant
links for load sharing, alarm thresholding, broadcast storm control, port
redirecting for traffic analysis, traffic priority configuration, and full error
breakdown. Per-port RMON support is also provided. By default, these modules
perform traditional switching (or bridging); each can also be configured to
perform prestandard IEEE 802.1Q VLAN switching (a.k.a “port-based VLAN”
switching).
The DLM6C-AA MultiSwitch 700 chassis itself offers the following features:
• Slots for up to 5 double-wide 2.4" interface modules, with chassis-wide
support of up to 130 users. Each interface module is individually driven and
managed by on-board processors, including an onboard ASIC processor for
switching, and Intel i960 Host microprocessors for dedicated module
management.
• A Frame Transfer Matrix (FTM) backplane design, that provides a separate
independent backplane connection from each module in the chassis to every
other module installed in the chassis. This allows a backplane bandwidth
capacity of up to 3.2 Gbps.
