System Reliability Guidelines

To help ensure proper cooling, performance, and system reliability, make sure that

the following requirements are met:

•

Each of the bays on the rear of the

Lenovo

Flex System chassis contains either

a module or a filler module.

•

A removed hot-swap module is replaced with an identical module or filler module

within one minute of removal.

•

A removed hot-swap compute node is replaced with another compute node or

filler node within one minute of removal.

•

The ventilation areas on the sides of the compute node are not blocked.

•

You have followed the reliability guidelines in the documentation that comes with

the

Lenovo

Flex System chassis.

Handling Static-Sensitive Devices

Attention:

Static electricity can damage the switch and other electronic devices. To

avoid damage, keep static-sensitive devices in their static-protective packages until

you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following

precautions:

•

Limit your movement. Movement can cause static electricity to build up around

you.

•

The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available.

•

Handle the device carefully, holding it by its edges or its frame.

•

Do not touch solder joints, pins, or exposed printed circuitry.

•

Do not leave the device where others can handle and damage it.

•

While the device is still in its static-protective package, touch it to an unpainted

metal part of any unpainted metal surface on a grounded rack component in the

rack in which you are installing the device, for at least two seconds. This drains

static electricity from the package and from your body.

•

Remove the device from its package and install it directly into the switch without

setting it down. If it is necessary to set down the device, put it back into its

static-protective package. Do not place the device on a switch cover or on a

metal surface.

•

Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

•

Some types of

Lenovo

Flex System chassis come with electrostatic discharge

(ESD) connectors. If your unit is equipped with an ESD connector, see the

documentation that comes with the

Lenovo

Flex System chassis for using the

ESD connector.

18 EN4093R 10 Gb Scalable Switch User’s Guide

Installing the EN4093R

Note: The following illustration shows how to install the switch in a

Lenovo

Flex

System chassis. The appearance of your

Lenovo

Flex System chassis might

be different; see the documentation for your

Lenovo

Flex System chassis for

additional information.

Use the following instructions to install the switch in the Lenovo Flex System

chassis. You can install the switch while the Lenovo Flex System chassis is powered

on. For redundancy support, you must install I/O modules of the same type in I/O

bays 1 and 2, and I/O modules of the same type in bays 3 and 4 of the chassis.

To install the switch, complete the following steps.

1. Read the safety information that begins on

page 5

and “Installation Guidelines”

on page 16.

2. Select I/O bay in which to install the switch.

Note:

For details about I/O bay requirements and bay locations, see the

documentation for the

Lenovo

Flex System chassis.

3. Remove the filler module from the selected bay. Store the filler module for

future use.

4. If you have not already done so, touch the static-protective package that

contains the switch to an unpainted metal surface of the

Lenovo

Flex System

chassis or an unpainted metal surface on any other grounded rack-component

for at least 2 seconds.

5. Remove the switch from its static-protective package.

6. Make sure that the release levers on the switch are in the open position

(perpendicular to the switch).

7. Slide the switch into the applicable I/O bay until it stops.

8. Push the release levers on the front of the switch to the closed position. After

you insert and lock the switch, it is turned on (there may be a slight delay), and

a Power-On Self-Test (POST) occurs to verify that the switch is operating

correctly.

Note:

The switch may take up to two minutes to complete the POST. During

POST, the Power LED continuously flashes. Once POST has successfully

completed, the Power LED remains on and the Error LED is off.

9. Make sure that LEDs on the switch indicate that it is operating correctly (see

“Information LEDs” on page 30).

10. If you have another switch to install, repeat Step 3 through Step 9; otherwise,

go to the next step.

11. Install any port transceiver modules or Direct-Attach Cables (DACs) needed for

the switch. For information and instructions, see “Connecting Switch Ports” on

page 21 and the documentation that comes with the transceiver modules or

DACs.

12. Attach any cables that are required by the switch. For additional information

about cabling the switch, see “Connecting Switch Ports” on page 21, the

documentation that comes with the port transceiver modules, DACs, cables,

and the optional network devices to which the cables are connected.

13. Make sure that the data (non-management) ports on the switch are enabled

through the Chassis Management Module (CMM).

Removing or Replacing the Switch

Note: The following illustration shows how to remove and replace the switch from

the

Lenovo

Flex System chassis. The appearance of your

Lenovo

Flex

System chassis might be different; see the documentation for your

Lenovo

Flex System chassis for additional information.

To replace the switch, complete the following steps.

1. Read the safety information that begins on

page 5

, and “Installation Guidelines”

on page 16.

2. Detach any cables that are attached to the switch you will be removing.

Note:

Detaching cables from the switch ports disrupts the network connection

from the switch to any connected external devices. If you plan to replace

the switch with another switch, you can reuse the existing cables, provided

they remains securely attached to the network.

3. Pull the release latches out from the switch. The switch moves out of the bay

approximately 0.6 cm (0.25 inch).

4. Slide the switch out of the bay and set it aside in a safe, static-free location.

5. Place either another switch or a filler module in the bay.
