Platform-Specific Information
IGX Switches
Like other Cisco WAN switches, the IGX switch operates in public or private WANs. An IGX switch can
support OC-3, T3, E3, T1, E1, inverse multiplexing over ATM (IMA) for T1 or E1, fractional T1 or E1,
or subrate digital transmission facilities. The IGX cell relay technology provides maximum throughput
with minimum delays. Cell relay performance characteristics are the core of efficient digital networks
and make the IGX switch an ideal choice for a multimedia platform. Key features of the IGX switch
include:
• A 1-Gbps Cellbus for high-speed switching and a redundant 0.2-Gbps bus for backup.
• Full compatibility with BPX system software.
• Up to 64 lines, 32 trunks, and 3500 terminating connections on the Cisco IGX 8410,
Cisco IGX 8420, and Cisco IGX 8430.
• IGX configuration and management through Cisco WAN Manager or the same standard user
interface used with the BPX WAN switching system software.
• High-performance switching suitable for a variety of protocols and applications, including
channel-associated signaling (CAS), ATM, Frame Relay, voice, fax, slow-scan and full-bandwidth
video, and synchronous or asynchronous data.
• Six cabinet models:
– An 8-slot standalone unit (Model 8410, standalone)
– An 8-slot rack-mount unit (Model 8410, rack-mount)
– A 16-slot standalone unit (Model 8420, standalone)
– A 16-slot rack-mount unit (Model 8420, rack-mount)
– A 32-slot standalone unit (Model 8430, standalone)
– A 32-slot rack-mount unit (Model 8430, rack-mount)
• Redundancy of controller cards, service module cards, system buses, and power supplies to provide
hardware reliability.
• Hot-swappable modules to facilitate nonstop operation: service cards, processor modules, AC and
DC power, and fan tray assembly.
• 110/220 VAC and –48 DC power options for use in varied network environments.
Universal Router Module
The URM is an optional module for the Cisco IGX 8400 series and delivers high-density voice
interfaces, Fast Ethernet connectivity, and ATM switching. The URM consists of the following cards:
• One URM front card. The 1-slot-wide front card contains an embedded UXM-E and an embedded
router (based on the Cisco 3660 series router) running Cisco IOS software. The front card integrates
all memory components, including Battery-Backed RAM (BRAM) and flash memory for the storage
of Cisco IOS software.
• URM back card options. All back cards are one slot wide. The following two options are for back
cards that support voice:
– BC-URI-2FE2VT1, providing two T1 ports (RJ-48), two 10/100BASE-T Fast Ethernet ports
(RJ-45), and one console port (RJ-45)
– BC-URI-2FE2VE1, providing two E1 ports (RJ-48), two 10/100BASE-T Fast Ethernet ports
(RJ-45), and one console port (RJ-45)
