2.3 Examining the installation site
2.
The QX-S5500G Series switches must be used indoors.
You can mount your switch in a rack, or on a workbench, and make sure:
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
The rack, or on the workbench have a good ventilation system.
Identify the hot aisle and cold aisle at the installation site, and make sure ambient air
flows into the switch from the cold aisle and exhausts to the hot aisle.
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of
the bottom device from entering the top device.
The rack, or the workbench are sturdy enough to support the switch and its
accessories.
The rack is well earthed.
To ensure normal operation and long service life of your switch, install it in an environment
that meets the requirements described in the following subsections.
2.3.1 Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
Lasting high relative humidity can cause poor insulation, electricity creepage,
mechanical property change of materials, and metal corrosion.
Lasting low relative humidity can cause washer contraction and ESD and bring
problems including loose captive screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly
lower the reliability and lifespan of the switch.
For the temperature and humidity requirements of different switch models, see "Technical specifications" of “Chapter 1 Product overview”.

3.5 Installing/removing a fan tray
CAUTION:
Install two fan trays of the same model on the switch. Do not power on the switch when it does not have fan
trays or has only one fan tray installed.
Make sure slots are installed with fan trays or blank filler panels for the device to operate.
At the first login to the QX-S5524GT-4X1C, QX-S5548GT-4X1C or QX-S5524GP-4X1C, use the fan
prefer-direction command to set the airflow direction of the switch to be the same as the airflow direction
of the fan tray. If the fan tray has a different airflow direction than the switch, the system outputs traps and
logs to notify you to replace the fan tray.
By default, the switch uses the same airflow direction (power-to-port) as the LSPM5FANSA fan tray.
If both fan trays fail during operation, replace them immediately. One fan trays don't make switch move,
please while breaking down.
Please don't remove a broken fan module until exchange preparations of a fan trays can be done.
If fan trays fail during operation, replace them within 2 minutes while the switch is operating. Please don't
make switch move in the state which has no fan trays for more than 2 minutes.
Failure to comply with these operating requirements may void the warranty.
The QX-S5524GT-4X1C, QX-S5548GT-4X1C or QX-S5524GP-4X1C switches support
hot-swappable fan trays.
The switch comes with empty fan tray slots. Choose the fan tray models based on the
ventilation requirement of the site. The air flow direction varies by fan tray model.
The LSPM5FANSA has a blue handle and provides power-to-port air flow.
The LSPM5FANSB has a red handle and provides port-to-power air flow.
3.5.1 Installing a fan tray

5.2 Planning IRF fabric setup
This section describes issues that an IRF fabric setup plan must cover.
5.2.1 Planning IRF fabric size and the installation site
Choose switch models and identify the number of required IRF member switches,
depending on the user density and upstream bandwidth requirements. The switching
capacity of an IRF fabric equals the total switching capacities of all member switches.
Plan the installation site depending on your network solution as follows:
Place all IRF member switches in one rack for centralized high-density access.
5-2
Page 64
Installation Guide
QX-S5500G Series Ethernet Switches
5. Setting up an IRF fabric
Distribute the IRF member switches in different racks to implement the top-of-rack
(ToR) access solution for a data center.
As your business grows, you can plug QX-S5500G Series Ethernet Switches into the IRF
fabric to increase the switching capacity without any topology change or replacement.
NOTE:
An IRF fabric of QX-S5500G Series can compose at most 9.
5.2.2 Identifying the master switch and planning IRF member IDs
Determine which switch you want to use as the master for managing all member switches
in the IRF fabric.
An IRF fabric has only one master switch. You configure and manage all member switches
in the IRF fabric at the CLI of the master switch. IRF member switches automatically elect a
master.
You can affect the election result by assigning a high member priority to the intended
master switch. For more information about master election, see QX-S5500G Series
Ethernet Switches Configuration Guides.
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to
uniquely identify and manage its members, and you must assign each IRF member switch
a unique member ID.
5.2.3 Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology or more reliable ring topology. In ring
topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain
topology. Instead, the IRF fabric changes to a daisy chain topology without interrupting
network services.
You co nnect the IRF member switches through IRF ports, the logical interfaces for the
connections between IRF member switches. Each IRF member switch has two IRF ports:

IRF-port 1 and IRF-port 2. To use an IRF port, you must bind a minimum of one physical
port to it.
When connecting two neighboring IRF member switches, you must connect the physical
ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
The QX-S5500G Series switches can provide 10-GE IRF connections through SFP+ ports
and 40-GE IRF connections through QSFP+ ports, and you can bind several SFP+/QSFP+
ports to an IRF port for increased bandwidth and availability.
Figure 5-2 and Figure 5-3 show the topologies of an IRF fabric made up of three
QX-S5524GT-4X1C switches. The IRF port connections in the two figures are for
illustration only, and more connection methods are available.

If a QSFP+ port is split into four SFP+ ports,
the QSFP+ port cannot be used as a
physical IRF port.

5. Setting up an IRF fabric
5.2.5 Planning the cabling scheme
Use SFP+/QSFP+ DAC cables or SFP+/QSFP+ transceiver modules and fibers to connect
the IRF member switches.
If the IRF member switches are far away from one another, choose the SFP+/QSFP+
transceiver modules with optical fibers. If the IRF member switches are all in one
equipment room, choose SFP+/QSFP+ DAC cables. For more information about
SFP+/QSFP+ DAC cables and SFP+/QSFP+ transceiver modules, see "Appendix C Ports
and LEDs."
The following subsections describe several NEC recommended IRF connection schemes,
and all these schemes use a ring topology.
IMPORTANT:
In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different
sides, you must measure the distance between them to select an appropriate cable.
I. Connecting the IRF member switches in one rack
Use SFP+ DAC cables to connect the IRF member switches (9 switches in this example) in
a rack as shown in Figure 5-4. The switches in the ring topology (see Figure 5-5) are in the
same order as connected in the rack.

5.3 Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF
member switch (see “Chapter 2 IRF” of QX-S5500G Series Ethernet Switches
Configuration Guides) to configure their member IDs, member priorities, and IRF port
bindings.
Follow these guidelines when you configure the switches:
Assign the master switch higher member priority than any other switch.
Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch.
You perform IRF port binding before or after connecting IRF physical ports depending
on the software release.
To bind the ports on an interface card to an IRF port, you must install the interface card
first. For how to install an interface card, see “Appendix B FRUs and compatibility
matrixes”.
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see “Chapter 2 IRF” of
QX-S5500G Series Ethernet Switches Configuration Guides.

To verify the basic functionality of the IRF fabric after you finish configuring basic IRF
settings and connecting IRF ports.
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF
settings and connecting IRF ports.
1) Log in to the IRF fabric through the console port of any member switch.
2) Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and
the remote network management station can reach each other.
3) Use Telnet, or SNMP to access the IRF fabric from the network management station.
(See “Chapter 1 Fundamentals” of QX-S5500G Series Ethernet Switches Configuration Guides.)
4) Check that you can manage all member switches as if they were one node.
5) Display the running status of the IRF fabric by using the commands in Table 5-2.
Table 5-2Displaying and maintaining IRF configuration and running status
Task Command
NOTE:
To avoid IP address collision and network problems, configure a minimum of one multi-active detection (MAD)
mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information
about MAD detection, see “Chapter 2 IRF” of QX-S5500G Series Ethernet Switches Configuration Guides.
This chapter describes types of software used on the switch and how to upgrade software
while the switch is operating normally or when the switch cannot correctly start up.
6.1 System software file types
Software required for starting up the switch includes:
Boot ROM image—Also called a Boot ROM image. This image is a “.bin” file that
contains a basic segment and an extended segment. The basic segment is the
minimum code that bootstraps the system. The extended segment enables hardware
initialization and provides system management menus. You can use these menus to
load software and the startup configuration file or manage files when the device
cannot start up correctly.
Comware image—Includes the following image subcategories:
Boot image—A “.bin” file that contains the Linux operating system kernel. It
provides process management, memory management, and file system
management.
System image—A “.bin” file that contains the Comware kernel and standard
features, including device management, interface management, configuration
management, and routing.
Comware images that have been loaded are called current software images. Comware
images specified to load at the next startup are called startup software images.
Boot image, and system image are required for the system to operate. These images might
be released separately or as a whole in one “.ipe” package file. If an “.ipe” file is used, the
system decompresses the file automatically, loads the .bin images and sets them as startup
software images.
6.2 System startup process
Upon power-on, the Boot ROM image runs to initialize hardware and then the software
images run to start up the entire system, as shown in Figure 6-1.

6.4 The overview of a CLI upgrade procedure
This section uses a two-member IRF fabric as an example to describe how to upgrade
software from the CLI. If you have more than two subordinate switches, repeat the steps for
the subordinate switch to upgrade their software. If you are upgrading a standalone switch,
ignore the steps for upgrading the subordinate switch. For more information about setting
up and configuring an IRF fabric, see “Chapter 5 Setting up an IRF fabric” and “Chapter 2
IRF“ of QX-S5500G Series Ethernet Switches Configuration Guides.
6.4.1 Preparing for the upgrade
Before you upgrade software, complete the following tasks:
1) Log in to the IRF fabric through Telnet or the console port (details not shown).
2) Perform the display irf command in any view to identify the number of IRF members,
Run a TFTP or FTP server program on the file server or the console terminal.
Copy the upgrade file to the file server.
Correctly set the working directory on the TFTP or FTP server.
Make sure that the file server and the switch can reach each other.
III. Verifying that sufficient storage space is available
IMPORTANT:
For the switch to start up correctly, do not delete the main startup software images when you free storage space
before upgrading Boot ROM. On the Boot menu, the main startup software images are marked with an asterisk
(*).
When you upgrade software, make sure each member switch has sufficient free storage
space for the upgrade file.
Upgrade images Minimum free storage space requirements
If no sufficient space is available, delete unused files.
IV. Scheduling the upgrade time
You must make sure the upgrade has a minimal impact on the network services. During the
upgrade, the switch cannot provide any services.
