Chapter 1. Product Overview; Ibm Y-Series Of Ethernet Switches - IBM 4002-Y2A Installation And User Manual

Chapter 1. Product overview

This guide describes the IBM y-series of Ethernet switches and includes procedures
for installing the hardware, and configuring essential basic parameters such as
permanent passwords and IP addresses. This guide also includes instructions for
managing and maintaining the hardware. The term y-series is used to distinguish
these Ethernet/IP switch models from other IBM Ethernet and IP router and switch
products. Through the remainder of this publication, these products will be
referred to generally as switches, by individual model names when necessary, and
as y-series switches when needed to distinguish from other switch product series.

IBM y-series of Ethernet switches

IBM y-series of Ethernet switches provide high 10/100/1000 Mbps port density
and available 10 Gbps Ethernet uplinks in a compact form factor. All y-series
models support Layer 2 and Enterprise Layer 3 protocols. Enterprise Layer 3
includes support for IPv4 unicast RIP and OSPF and IPv4 multicast PIM.
This section describes the physical characteristics of the IBM y-series of Ethernet
switches. For more details about physical dimensions, power supply specifications,
and pinouts, refer to Chapter 5, "Hardware specifications," on page 49.
Note: Not all y-series models are available in all markets.
The IBM y-series of Ethernet switches includes the following models:

operates as combination (Combo) ports or a 4-port 10 GbE SFP+ module. Two
rear power supply receptacles allow for up to two 210 W power supply units
("-E" versions). These switches support port to non-port side (front to back)
airflow.

(Combo) ports which include four 10/100/1000 MbE RJ45 ports and four
100/1000 MbE SFP ports. The RJ45 ports support Power over Ethernet Plus
(PoE+). Two dedicated 16 Gbps CX4 ports on the rear panel allow stacking for
up to eight units. The front panel also has one module slot for an optional 2-port
10 GbE XFP module. Two rear power supply receptacles allow for up to two 620
W power supply units. Airflow is from the left side to right side (when facing
the port side of the switch).
