Technology That Preserves Your Investment

Designed for Scalability

Summit 400-48t delivers 10/100/1000

density, scalability and port ﬂexibility

allowing customers to easily expand

their network and make the most efﬁcient

use of available rack space. In just 1.75”

(1RU), Summit 400-48t supports:

48 copper Gigabit Ethernet ports

(10/100/1000BASE-T)

4 ports of SFP MiniGBICs (logically

shared with the 1000BASE-T

ports)

2 ports of 10 gigabit uplinks

(optional)

10/100/1000 port for out-of-band

management

1 serial port

160 Gigabit per Second Switch

Fabric

Summit 400-48t delivers outstanding

switch fabric and throughput perfor-

mance giving users the bandwidth their

applications require. Summit 400-48t has

160 gigabits per second (Gbps) capacity

supporting 101 million packets per

second, making it a high-performance

ﬁxed conﬁguration edge switch. This

helps ensure that Summit 400-48t will

have the capacity to support ever-

growing end user bandwidth require-

•

ments. The two 10 gigabit uplinks, high-

performance switch fabric and 101 Mpps

throughput ensure that Summit 400-48t

will continue to be a critical edge solution in

your network for years to come.

Small, Medium, Large Networks

Supported

Summit 400-48t supports up to 16,000

MAC addresses, 4,000 Layer 3 forwarding

database entries in hardware or 64,000

routing table entries, making this an ideal

switch for both wiring closet implementa-

tions and enterprise branch ofﬁces. Even

as your network grows, the large table

sizes supported in Summit 400-48t make

this an excellent long-term solution more

than capable of supporting network growth.

Wire-Speed Access Control Lists

Wire-speed Access Control Lists (ACLs)

are powerful security tools and the use of

ACLs in networks is likely to increase as a

way to combat security threats. However,

the value of ACLs is diminished if by

applying them, trafﬁc slows down, creating

a congestion point. Summit 400-48t

delivers wire-speed ACLs on every port for

security while maintaining throughput.

With Summit 400-48t, an IT manager can

turn on ACLs whenever they are needed

without worrying about disrupting business

applications or reducing productivity.

Jumbo Frame Support

Jumbo frames of up to 9,216 bytes are

supported—making Summit 400-48t an

ideal switch for new applications requiring

large frames such as storage and graphic/

video applications. Studies have indicated

that jumbo frames are particularly impor-

tant in high performance cluster computing

applications where their use can reduce

server CPU loads by as much as 50%.

10 Gigabit Ethernet at the

Edge–When You Need It

Summit 400-48t delivers the industry’s ﬁrst

ﬁxed conﬁguration edge switch with two 10

gigabit uplinks so the edge switch uplink

capacity can grow as the end user’s

bandwidth demands grow. Based on a

modular design, an optional 10 gigabit

“daughter card” can be added to

Summit 400-48t delivering immediate

support for two 10 gigabit XENPAK I/O

modules. This advanced design enables the

user to easily upgrade Summit 400-48t to

multiple 10 gigabit uplinks when added uplink

capacity is required.

UniStack Stacking to Support

Converged Services

Latency and jitter can be lethal to real-

time applications, such as voice and video.

Summit 400-48t and UniStack stacking

architecture were designed to support

converged services. The signiﬁcant

throughput provided by UniStack stack-

ing—up to 160 Gbps per stack, and the

distributed, shortest path forwarding—

provides performance comparable with

chassis switches. Resiliency is of key

importance for these converged applica-

tions like video and IP Telephony and is

assured by redundant bidirectional ring

architecture and n-1 master redundancy,

distributed Layer 2 and Layer 3 link

aggregation, link redundancy, and

distributed uplinks. The resulting network

simpliﬁcation yields lower management

and maintenance costs, while enhancing

overall availability. UniStack stacking on

Summit 400 series switches transfers

inter-switch packets at a nominal 20 Gbps,

with instantaneous throughput at any

switch reaching 40 Gbps, and a total stack

bandwidth peaking at 160 Gbps.

With UniStack stacking, Summit 400-48t and other switches in the Summit 400 product family, deliver the best of both

worlds: the beneﬁts of a chassis at the cost of a stackable in an architecture designed to support today’s evolving LAN

applications. The resulting network simpliﬁcation yields lower management and maintenance costs, while enhancing

overall availability. UniStack stacking on Summit 400-48t preserves the initial network investment while providing the

ﬂexibility to build and expand as network requirements grow.
