Installing the Switch in the Rack

Minimum and Maximum Rack Depth for these switches

Make sure that the Installation kit you have is compatible with your rack.

To use the IS50XX series switch in a rack deeper than 50cm, order the switch with the standard

depth, or order the MIS000083 installation kit. The both of these solutions will allow you to install

the switch in a 19” rack whose vertical supports are between 50cm and 80cm apart.

Tools and Parts

Tools required and customer supplied parts

Parts Included in the Installation Kit:

Figure 1: Rack Installation Kit Parts

Before you install your new switch, unpack the system and check to make sure that all the parts have been

sent, check this against the parts list. Check the parts for visible damages that may have occurred during

shipping.

Note: If anything is damaged or missing, contact your customer representative immediately.

Procedure

Step 1. Place the ESD mat on the floor where you will be working and put on the ESD strap. Make

sure the ESD strap is touching your skin and that the other end is connected to a verified

ground.

Step 2. Choose which side of the switch you want even with the vertical rack support. Either

the side with the power supply units or the side with the IB connectors can be even

with the vertical rack support. The other side of the switch will be further inside of the

rack.

Things to consider before choosing where to mount the rails and rail slides.

• Phillips Screwdrivers #1 and #2 • Grounding screw

• ESD Strap • Grounding wire sufficient to reach a valid ground

• ESD mat

• 2 rails • 18 recessed flat head screws

• 2 rail slides • 8 caged nuts

• 2 brackets • 8 pan head screws M6

Figure 2: Which Side of the Rack Do You Want the Connectors?

• Do you want the connector side recessed in the rack to allow for larger cable bending radius?

• Will the connector side be recessed past other equipment in the rack and will this be problematic?

Step 3. Screw the brackets onto the switch. Use the flat head screws to connect the bracket.

There are two options for mounting the bracket. One option will place the switch even

with the vertical support of the rack and the second option will recess the switch fur-

ther into the rack.

Note: The side of the switch with these brackets will be the side that is even with the vertical rack support.

Step 4. Screw the rails onto the switch. Use the 5 flat head screws to connect each rail to the

switch.

The distance between the rack and the door can be as little as 4 cm on one side

of the rack and as much as 18 cm on the other side of the rack. Keep in mind that

there can be as many as 36 cables connected to the switch.

In this position you will use 4 flat

head screws

Step 5. Clip the 4 caged nuts into the holes in the rack you will be using to connect the rail

slides. Check that both sides of the switch, left and right, are in the same position num-

ber on the rack.

Step 6. Clip 4 more caged nuts into the holes in the rack you will be using to connect the

brackets. Check that both sides of the switch, front and back, are in the same position

number on the rack.

Note: The rail slides are to be installed on the side of the rack where the switch will be recessed into the

rack.

Step 7. Using two of the bolts for each rail slide, install the rail slides to the rack.

Tighten the bolts to 9.2 Nm or 81.5 pound inches.

Step 8. If the power cable is on this side of the switch feed the power cable into the slot in the

rail slide before screwing it to the vertical support.

Step 9. Place the four bolts for the caged nuts within reach.

Step 10. Slide the switch into the rails.

Step 11. Put the switch into place and screw the bolts into the nuts from step 6. If the power

cable is on this side of the switch feed the power cable into the slot in the bracket

before screwing it to the vertical support.Tighten the bolts to 9.2 Nm or 81.5 pound

inches.

Step 12. Tighten all of the screws to 9.2 Nm or 81.5 pound inches.

Step 13. Plug in the power cables.

Note: When the switch is plugged in, the status LED may be RED for up to three minutes until the system

completes booting up.

The caged nuts

are separated by a

single space

Step 14. Check the Status LEDs and confirm that all of the LEDs show status lights consistent

with normal operation.

Step 15. You can start connecting all of the cables to the switch.

Grounding the Switch

You must install an external ground to all IT components. To this purpose there are two threaded screw

holes marked as grounds. Connect a ground wire to one of these grounds and connect the other end to a

valid ground. Do not rely on the power connection ground. If you choose to not use the ground screw,

make sure that there is a valid ground connection between the chassis of the switch and the grounded rack.

Test the ground using an Ohm meter.

Note: Grounding wires, screws, and connectors for the ground are not supplied by Mellanox.

Configuring the Switch for the First Time

Note: Unmanaged (Externally managed) switches, that is the IS5025 switches, do not get configured. On

unmanaged switches, the CONSOLE, Ethernet, and USB connectors are not found. Instead there is

an I2C connector.

Step 1. Connect the host PC RS232 connector to the CONSOLE port of the switch using the supplied

cable

Note: No remote IP connection is available at this stage.

Step 2. Configure a serial terminal program (for example, HyperTerminal, Minicom, or Tera

Term) on your host PC with the settings described in Table 3.

Step 3. Login (from serial terminal program) as admin and use admin as password. This starts

the Mellanox configuration wizard.

Step 1. Go through the Mellanox configuration wizard. Table 4 shows an example of a wizard session.

Wizard Session Display (Example) Comments

Mellanox configuration wizard

Do you want to use the wizard for initial configuration? yes

You must perform this configura-

tion the first time you operate the

gateway or after resetting the

gateway password. Type ‘y’ and

then press <Enter>.

Step 1: Hostname? [bridge-1] If you wish to accept the default

hostname, then press <Enter>.

Otherwise, type a different host-

name and press <Enter>.

Step 2: Use DHCP on eth0 interface? Yes Perform this step to obtain an IP

address for the gateway. (eth0 is

the management port of the gate-

way.)

If you wish the DHCP server to

assign the IP address, type ‘yes’

and press <Enter>.

If you type ‘no’ (no DHCP), then

you will be asked whether you

wish to use the ‘zeroconf’ config-

uration or not. If you enter ’yes’

(yes Zeroconf), the session will

continue as shown in Table 5.

If you enter ’no’ (no Zeroconf),

then you need to enter a static IP,

and the session will continue as

shown in Table 6.

Step 3: Admin password (Enter to leave unchanged)?

<new_password>

Step 4: Confirm admin password? <new_password>

To avoid illegal access to the

machine, please type a password

and then press <Enter>. Then

confirm the password by re-

entering it.

Note that password characters are

not printed.
