CN1610 Switch Features
About this chapter This chapter describes the CN1610 switch hardware components and software
features and provides technical specifications.
Topics in this
chapter This chapter includes the following topics:
u“Hardware components” on page 6
u“Software features” on page 12
u“Technical specifications” on page 18
CN1610 summary The CN1610 is a high bandwidth, managed Layer 2 switch that provides 16
10-Gigabit Small Form-Factor Pluggable Plus (SFP+) ports. The switch includes
redundant power supplies and fan trays that support hot swapping for high
availability.
This 1U switch can be installed in a standard 19-inch IBM N series 42U system
cabinet or third-party cabinet.
The switch supports local management through the console port or remote
management by using Telnet or SSH through a network connection. The CN1610
includes a dedicated 1-Gigabit Ethernet RJ45 management port for out-of-band
switch management. You can manage the switch by entering commands into the
command-line interface (CLI) or by using an SNMP-based network management
system (NMS).

SFP+ ports The CN1610 has 16 built-in 10-Gbps SFP+ ports that provide up to 256 Gbps
switching bandwidth (512 Gbps duplex).
Each SFP+ port is capable of supporting the following transceiver modules:
u10GBase-Cu (direct attach SFP+ twinax copper cable)
u10GBase-SR (short range optical fiber)
Four 10G SPF+ direct attach cables are included in the shipping package. Other
transceivers and cables are sold separately.
Remote
management port The remote management port is a 10/100/1000Base-T Ethernet port dedicated to remote switch management. Traffic on this port is segregated from operational
network traffic on the switch ports and cannot be switched or routed to the
operational network.
Console port The console (RJ45) port is used only for management through a serial interface.
This port provides a direct connection to the switch and allows you to access the
CLI from a console terminal connected to the port through the provided serial
cable (RJ45 to female DB-9 connectors).
The console port supports asynchronous data of eight data bits, one stop bit, no
parity bit, and no flow control. The default baud rate is 9600 bps.
The pin assignment for the console port is shown in the following table:

Port LED definitions Each SFP+ port has two built-in LEDs that provide port link, activity, and speed
information. Similarly, the remote management port has two built-in LEDs to
provide information about the port link, activity, and speed.
For the switch ports and remote management port, the Speed LED is on the upper
left side of the port, and the Link/Activity LED is on the upper right side of the
port:
The following table describes the Speed and Link/Activity LEDs found above
each SFP+ port:
SFP+ port
LED Color Description
Speed Solid green A valid 10 Gbps link is established on the
port.
Off No link or a valid 1 Gbps link is established
on the port.
Link/Activity Solid green A valid link is established on the port.
Blinking

Chapter 1: CN1610 Switch Features 9
The following table describes the Speed and Link/Activity LEDs found above the
remote management port:
Power supplies The CN1610 has two internal, replaceable AC power supplies for redundant or
load-sharing operation. Each power supply can provide 300 watts and includes
hot-swap support.
Each power supply receives power by connecting an AC power source to the
power socket on the rear panel of the switch.
Although the cluster network switch has redundant power supplies and can
operate normally when only one power supply is installed and operational, IBM
recommends that you replace any failed power supply immediately to maintain
redundancy. If one power supply fails, a second power supply must be present
and functional for the switch to continue to operate.
Fan units The two fan trays in the CN1610 support hot-swapping and can be removed or
inserted from the front panel. Each fan tray includes two fans. For the switch to
maintain an acceptable operating temperature, both fan trays must be present in
the chassis, and all four fans must be operational.

Speed Solid green A valid 1000 Mbps link is established on
the port.

12 Software features
Software features
Operating system
features The switch operating system features include those that allow you to define the switch within your network and manage or monitor various hardware and
software aspects.
The following table describes the system features:
System feature Description
Remote management Remote management of the switch over the in-band
network is available by using any of the following
protocols:
uTelnet
uSSH v1.5, v2
uTFTP
uSNMP v1/v2c/v3
BootP/DHCP client Automatically obtain network information, such as
an IP address for the management interface, from a
BootP or DHCP server on the network.
SNTP client Synchronize the time on the switch with a remote
SNTP server. The switch supports SNTP Version 4.
DNS client Specify the DNS server to use to resolve host names
to IP addresses.
Dual image support Store up to two software images and two
configuration files on the switch flash file system.
This allows you to upgrade the switch software
while leaving the possibility of reverting to the old
software or old configuration.
File download and
upload Download files such as firmware images and configuration files to the switch by using TFTP, SCP,
SFTP, and XMODEM. Files can also be uploaded
from the switch to a remote system.

Chapter 1: CN1610 Switch Features 13
CLI scripting Download a text file containing CLI commands to
the switch and execute all commands in order. The
script can be modified and downloaded to multiple
switches.
IPv6 management The switch supports the following IPv6 management
protocols and applications:
uPingv6
uTraceroutev6
uTFTP
uSSH
uSSL
uTELNET
uSNMP
Logging Maintain a record locally on the switch or on a
remote Syslog server of switch events, including CLI
commands executed on the switch. Control the
severity of messages to log.
System monitoring View information about the system temperature,
power supply, and fan status.
Remote monitoring
(RMON) The switch supports the following four groups defined as part of the RMON standard:
uStatistics
uHistory
uAlarms
uEvents
System feature Description

14 Software features
Switching features The switching features include the Layer 2 features described in the following
table:
Switching feature Description
IEEE 802.3x flow
control Allow lower speed switches to communicate with higher speed switches by handling requests for the
higher speed switch to refrain from sending packets.
Transmissions are temporarily halted to prevent
buffer overflows.
Port control Configure individual port settings such as
administrative status, speed, duplex, and
autonegotiation mode.
Jumbo frames On a per-port basis, extend the maximum frame size
(Ethernet MTU) that a port can transmit from 1518
bytes (1522 bytes with VLAN header) to up to 9216
bytes.
Layer 2 forwarding
database (L2FDB)
control
Add static addresses or clear the L2FDB and control
the number of entries that can be dynamically
learned.
Layer 2 multicast
forwarding database
(MFDB) control
Limit multicasts to only certain ports in the switch to
prevent traffic from going to parts of the network
where that traffic is unnecessary.
VLANs Optimize network traffic patterns by creating
VLANs and configuring member ports so that
broadcast, multicast, and unknown unicast packets
are sent only to ports that are members of the VLAN.
Protocol-based
VLANs Define a packet filter that the switch uses as the matching criteria to determine if a particular packet
belongs to a particular VLAN. With protocol-based
VLANs, traffic is bridged through specified ports
based on its protocol.
MAC-based VLANs Assign incoming packets to VLANs based on the
source MAC address of the packet.
IP subnet-based
VLANs Assign incoming packets to VLANs based on the source IP address of the packet.
