x IBM System Networking RackSwitch G8000: Installation Guide

CAUTION: v Do not install a unit in a rack where the internal rack ambient temperatures

will exceed the manufacturer’s recommended ambient temperature for all your rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure

that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

v Consideration should be given to the connection of the equipment to the

supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.

v (For sliding drawers) Do not pull out or install any drawer or feature if the

rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and must not be moved

for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

xiv IBM System Networking RackSwitch G8000: Installation Guide

Chapter 1. Introduction

This Installation Guide provides information and instructions for installing an IBM System Networking RackSwitch management of the switch, see the Command Reference and the product release notes.

The RackSwitch G8000 is a rackable aggregation switch with unmatched line-rate Layer 2/3 performance. The G8000 uses a wire-speed, non-blocking switching fabric that provides simultaneous wire-speed transport of multiple packets at low latency on all ports.

The G8000 contains forty-eight 1GbE SFP+ ports:

v Forty-four 10/100/1000BaseT ports (RJ-45) v Four SFP slots

The G8000 includes two port expansion slots for dual-port, 10 GbE uplink modules with SFP+ or CX4 transceivers. One slot is located on the front panel, and one slot is located on the rear panel.

You can manage the switch through the console port, or through a network connection using Telnet, a Web browser-based interface, or SNMP-based network management software.

This 1U switch is rack mountable in either the horizontal or vertical direction, depending on your application.

™

Figure 3. IBM RackSwitch G8000 rear panel

Fans

Up to five internal fans cool the switch unit. If an individual fan fails, the other fans continue to run, and the switch unit continues to operate normally. Fans are not customer replaceable.

Note: If a fan module fails, the maximum operating temperature drops from 40°C to

35°C (104°F to 95°F).

Chapter 1. Introduction 5

The Fan LED flashes if there is a failure of one or more fan modules.

AC power supply

The switch has two redundant 150 W AC power supplies. Each internal power supply has an individual IEC 320 power connector on the rear panel. The power cord attaches to a universal grounded AC power source. You can replace a hot-swap power supply module without powering off the switch or disrupting switch functions.

DANGER

Each power supply can be connected to a separate AC circuit to mitigate the risk of down time during a power failure. When used in a redundant configuration, the dual power supplies have a load-sharing capability that enables each power supply to operate at approximately 50% of full load. Using redundant power can minimize the power disruption during a power supply failure and extend the expected lifetime of each power supply by operating normally in a conservative power mode.

There is no power switch on the G8000; the switch unit powers up when power is supplied through the power cords.

The Power Supply LED indicates the status of the power supplies. The LED flashes when only one power cord is connected, and is steady when both power cords are connected.

DC power supply

The DC-powered G8000 has two redundant 160 W DC-DC power supplies, operating from 42V to 60V. Each internal power supply has a DC filter input on the rear panel. The DC power sources are connected to the RackSwitch through the mating connector cable assemblies provided. One end of the cable is connected to the switch and the three DC-input leads connect the DC-input power supply to the site power source. The pigtail end of the cable is color coded, as follows:

There is no power switch on the RackSwitch; the switch unit powers up when power is supplied through the DC power source.

The Power Supply LED indicates the status of the power supplies. The LED flashes when only one DC power source is connected, and is steady when both DC power sources are connected.

The RackSwitch ports and port options are described in the following sections.

10/100/1000 Base-T ports

Forty-four 10/100/1000Base-T ports (RJ-45) are located on the front panel. In-line management and Control Plane Stacking are supported by using one or more of the RJ-45 ports for management.

The G8000 is designed to accept most standard 10/100/1000Base-T (category 5) cables.

10 Gigabit Ethernet port expansion slots

The RackSwitch unit includes two port expansion slots, one on the front panel and one on the rear panel. Each expansion slot accepts a dual-port 10 GbE (XGE) uplink module for either CX4 or Small Form-factor Pluggable Plus (SFP+).

You can add one or two XGE uplink modules, as follows:

SFP+ Uplink Module

Up to four 10 Gbps SFP+ modules can be installed on the RackSwitch. These ports accept approved optical SFP+ transceivers. SFP+ transceivers can be purchased separately.

Switch LEDs

CX4 Uplink Module

Up to four CX4 ports can be installed on the . These ports provide CX4 connectivity between the RackSwitch and copper 10 GbE CX4 network devices. The CX4 ports support link spans up to 15 meters on appropriate CX4-grade copper cables.

The CX4 ports provide powered CX4 automatically. The port detects when a powered CX4 device is connected, and sends power to the device.

The RackSwitch is designed to accept most standard 10 GbE CX4 cables. For the available transceivers and direct attach cables (DACs) for the switch, see: https://www-01.ibm.com/products/hardware/configurator/americas/bhui/launchNI.wss.

Note: Do not use InfiniBand CX4 cables with the RackSwitch. Although InfiniBand

cables have the same CX4 connectors as 10GBase-CX4 cables, InfiniBand cables do not adhere to the same standard as 10GBase-CX4 cables.

Two LED stacks provide system status and port link status. The following illustration shows the system LEDs.
