Signal Function Signal Function

To establish normal communication, pin for transmission data has to make them match with pin for receive data in an opposite port. When a port of one device is MDI or MDI-X, and a port of the device opposite is already MDI or MDI-X, a crossing cable is necessary. The MDI/MDI-X type connects the same device to a crossing cable. When MDI and the other are MDI-X, a straight cable needs one port. A straight cable connects device different in the MDI/MDI-X type.

When the auto-MDI/MDI-X function is effective by RJ-45 Ethernet interface, the role of the pin is put together automatically.

NOTE:

RJ-45 Ethernet interface of QX-S5500 series is supporting auto-MDI/MDI-X function. The auto-MDI/MDI-X function is effective at a port by default.

5.1.2 Connection by a twisted pair cable

10/100/1000BASE-T port of QX-S5500 series uses RJ-45 connector and supports auto-MDI/MDI-X function. Use a twisted pair cable of Category - more than 5 for a network connection of the switch.

I. Network connection procedure of the switch by a twisted pair cable

1) As occasion demands, make straight or a cross Ethernet cable.

2) A something of a twisted pair cable is connected to Ethernet RJ-45 port of the connected switch.

3) Connect the other end of a twisted pair cable to Ethernet RJ-45 port of interconnect equipment.

4) Check whether an LED in Ethernet RJ-45 port is normal.

[ftp] bye

2) Specify the software used at next-startup.

<QX> boot-loader file SWITCH.app slot 1 main

<QX> display boot-loader

The main boot app is: flash:/SWITCH.app

<QX> reboot

Before restarting the switch, make sure other configurations are all saved to avoid the loss of configuration information.

Therefore specification of the software used at next-startup is completed. To confirm the upgrade of software, restart the switch. After a load of Boot Rom has been completed when space of a flash memory isn't enough, it's possible to delete several files in the flash memor y. It's recommended to delete the software which isn't used. Upload software using a F T P. Power interruption is not allowed during software loading.

6.3.2 Upgrade of software by TFTP

The remote loading by using TFTP is similar to the remote loading by using FTP. The only difference is that it is TFTP that you use when loading software to the switch. In this case, the switch can only be used as a TFTP client. The remaining step after download is just same as the occasion of the remote load with a FTP.

7.1 Exchange of a power supply module

CAUTION:

QX-S5526T has power supply module of the AC type and DC-type. You can select AC power module or DC power module for your switch as needed. Install power supply modules of the same model on the switch. for power supply redundancy or a maintenance exchange.

I. Installation tools

 ESD-preventive wrist strap  Phillips screwdriver

II. Exchange of a power supply module

1) Reduce a fixed screw of the power supply module using a screwdriver.

2) Draw an exchanged module and remove a slot.

3) Take new power supply module out from a package.

4) Confirm whether power supply module is for AC power supplies or DC power supply.(see Figure 7-1)

Figure 7-1 Power supply module (left: AC power module, right: DC power module)

CAUTION:

 The power supply module is heavy, so please treat by both hands. Correctly orient the power module with

the power supply module slot, grasp the handle of the power supply module with one hand and pull the handle slowly with opposite hand. If only one power supply module is installed, install a power filler module in the empty power supply module slot for good ventilation of the switch.

 To prevent damage to the connectors inside the switch chassis, insert the power supply module gently. If

you encounter a hard resistance while inserting the power supply module, pull out the power module and insert it again.

 When a fixed screw doesn't tighten well, there is a possibility that a power supply module isn't inserted right.

Confirm whether a power supply module is inserted correctly.

software file.

When there are no problems with both of a connection in a physical port and the free space of the flash memory, verify the message about an input error of the upgrade procedure shown to a terminal.

1) When a baud rate is established besides the 9600 bps after loading software in a case with Xmodem, please verify whether it was set as 9600 bps once again.

2) When using TFTP, please verify whether the next is specified right.

 A server and the switch IP address are right.  The name of the loaded software is right.  The TFTP server address which moves on the program file is right.

3) When using FTP, please verify whether the next is specified right.

 A server and the switch IP address are right.  The name of the loaded software is right.  A username and a password are right.
