Flex I/O Cards and Port Modules

Flex I/O Cards (flex IOCs) are IOCs with two slots, which accept port modules that
add Ethernet ports to your services gateway. A flex IOC with installed port modules
functions in the same way as a regular IOC, but allows greater flexibility in adding
different types of Ethernet ports to your services gateway. Figure 1 on page 2 shows
a flex IOC with two typical port modules installed.

Figure 1: Flex IOC with Port Modules

NOTE: Your services gateway must be running JUNOS version 9.5R1 or later in order
to recognize flex IOCs and port modules.

Each flex IOC has a processor subsystem, which includes a 1.2-GHz CPU, a system
controller, 1 GB SDRAM, and two Packet Forwarding Engines (PFEs) with a maximum
throughput of 10 Gbps each. See “Installing a Flex IOC” on page 11 and “Removing
a Flex IOC” on page 9 for information about installing and removing flex IOCs.

Table 1 on page 2 describes the different port modules available.

Handling and Storing Cards

This section explains how to avoid damaging the cards (IOCs, SPCs, host subsystems,
and port modules) that you install into the services gateway. Many components on
the cards are fragile.

CAUTION: Failure to handle cards as specified in this document can cause irreparable
damage.

This section discusses how to hold cards in both the vertical and horizontal positions.
Regardless of orientation, this section uses the same terms for all four edges of the
card (see Figure 3 on page 6):

■ Faceplate—Edge of the card that has connectors to which you connect cables or

sockets for SFP or XFP transceivers.

■ Connector edge—Edge opposite the faceplate; this edge has the connectors that

attach to the midplane.

■ Top edge—Edge at the top of the card when it is vertical.

■ Bottom edge—Edge at the bottom of the card when it is vertical.

NOTE: The instructions in this section apply to all card and port module types.

SRX 5600 and SRX 5800 Services Gateway Flex IOC and Port Module Installation Instructions

Figure 3: Card Edges

Holding a Card

When you carry a card, you can hold it either vertically or horizontally.

NOTE: A card weighs up to 13.1 lb (5.9 kg). Be prepared to accept the full weight of
the card as you lift it.

To hold a card vertically:

1. Orient the card so that the faceplate faces you. To verify orientation, confirm

that the text on the card is right-side up and the electromagnetic interference
(EMI) strip is on the right-hand side.

2. Place one hand around the card faceplate about a quarter of the way down from

the top edge. To avoid deforming the EMI shielding strip, do not press hard on
it.

3. Place your other hand at the bottom edge of the card.

If the card is horizontal before you grasp it, place your left hand around the faceplate
and your right hand along the bottom edge.

To hold a card horizontally:

1. Orient the card so that the faceplate faces you.

2. Grasp the top edge with your left hand and the bottom edge with your right hand.

6 ■ Handling and Storing Cards

Handling and Storing Cards

You can rest the faceplate of the card against your body as you carry it.

As you carry the card, do not bump it against anything. Card components are fragile.

Never hold or grasp the card anywhere except the places that this document indicates.
In particular, never grasp the connector edge, especially at the power connector in
the corner where the connector and bottom edges meet (see Figure 4 on page 7).

Figure 4: Do Not Grasp the Connector Edge

Handling and Storing Cards ■ 7

SRX 5600 and SRX 5800 Services Gateway Flex IOC and Port Module Installation Instructions

Never carry the card by the faceplate with only one hand.

Do not rest any edge of a card directly against a hard surface (see Figure 5 on page

8).

Do not stack cards.

Figure 5: Do Not Rest the Card on an Edge

If you must rest the card temporarily on an edge while changing its orientation
between vertical and horizontal, use your hand as a cushion between the edge and
the surface.

Storing a Card

You must store a card as follows:

■ In the device chassis

■ In the container in which a spare card is shipped

■ Horizontally and sheet metal side down

When you store a card on a horizontal surface or in the shipping container, always
place it inside an antistatic bag. Because the card is heavy, and because antistatic
bags are fragile, inserting the card into the bag is easier with two people. To do this,
one person holds the card in the horizontal position with the faceplate facing the
body, and the other person slides the opening of the bag over the card connector
edge.

8 ■ Handling and Storing Cards

If you must insert the card into a bag by yourself, first lay the card horizontally on
a flat, stable surface, sheet metal side down. Orient the card with the faceplate facing
you. Carefully insert the card connector edge into the opening of the bag, and pull
the bag toward you to cover the card.

Never stack a card under or on top of any other component.

Replacing Flex IOCs and Port Modules

You install flex IOCs and port modules in the front of the services gateway. You install
flex IOCs directly in the card cage. You install port modules into flex IOCs. Flex IOCs
and port modules are hot-insertable and hot-removable. When you remove a flex
IOC or port module, the services gateway continues to function, although the flex
IOC or port module being removed no longer functions. Before replacing a flex IOC
or port module, review the information in “Handling and Storing Cards” on page 5.
To replace a flex IOC or port module, use the following procedures:

■ Removing a Flex IOC on page 9

■ Installing a Flex IOC on page 11

■ Removing a Port Module on page 12

■ Installing a Port Module on page 14

Replacing Flex IOCs and Port Modules

Removing a Flex IOC

A flex IOC weighs up to 13.1 lb (5.9 kg). Be prepared to accept the full weight of the
card as you remove it.

To remove a flex IOC (see Figure 6 on page 10):

1. Have ready a replacement card or blank panel and an antistatic mat for the flex

IOC.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis. For more information
about ESD, see “Preventing Electrostatic Discharge Damage” on page 16.

3. Use one of the following methods to take the flex IOC offline:

■ Press and hold the corresponding online button on the craft interface. The

green OK LED next to the button begins to blink. Hold the button down until
the LED goes off.

■ Issue the following CLI command:

user@host>request chassis fpc slot slot-number offline

For more information about the command, see the JUNOS System Basics and
Services Command Reference.

4. If you have not already done so, remove the port modules installed in the flex

IOC as described in “Removing a Port Module” on page 12.

5. Simultaneously turn both of the ejector handles counterclockwise to unseat the

flex IOC.

6. Grasp the handles and slide the flex IOC straight out of the card cage halfway.

7. Place one hand around the front of the flex IOC and the other hand under it to

support it. Slide the flex IOC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.

CAUTION: The weight of the flex IOC is concentrated in the back end. Be prepared
to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the flex IOC out of the
chassis.

When the flex IOC is out of the chassis, do not hold it by the ejector handles, bus
bars, or edge connectors. They cannot support its weight.

Do not stack flex IOCs on top of one another after removal. Place each one individually
in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

8. If you are not reinstalling a replacement card into the empty slot within a short

time, install a blank panel over the slot to maintain proper airflow in the card
cage.

CAUTION: After removing an IOC from the chassis, wait at least 30 seconds before
reinserting it, removing an IOC from a different slot, or inserting an IOC into a
different slot.

to recognize flex IOCs and port modules.

To install a flex IOC (see Figure 7 on page 11):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis. For more information
about ESD, see “Preventing Electrostatic Discharge Damage” on page 16.

2. Place the flex IOC on an antistatic mat or remove it from its electrostatic bag.

3. Identify the slot on the services gateway where you will install the flex IOC.

4. If you have not already done so, remove the blank panel from the slot where

you are installing the flex IOC.

5. Orient the flex IOC so that the faceplate faces you.

6. Lift the flex IOC into place and carefully align the sides of the card with the guides

inside the card cage.

7. Slide the flex IOC all the way into the card cage until you feel resistance.

Figure 7: Installing a Flex IOC

8. Grasp both ejector handles and rotate them clockwise simultaneously until the

flex IOC is fully seated.

9. Use one of the following methods to bring the flex IOC online:

■ Press and hold the corresponding online button on the craft interface until

■ Issue the following CLI command:

the green OK LED next to the button lights steadily, in about 5 seconds.

For more information about the command, see the JUNOS System Basics and
Services Command Reference.

CAUTION: After the OK LED turns green, wait at least 30 seconds before removing
the IOC again, removing an IOC from a different slot, or inserting an IOC in a different
slot.

Removing a Port Module

Port modules are installed in flex IOCs in the services gateway card cage. A port
module weighs up to 3 lb (1.4 kg). Be prepared to accept its full weight when you
remove or install a port module.

To remove a port module (see Figure 8 on page 13):

1. Have ready a replacement port module or blank panel and an antistatic mat for

the port module. Also have ready rubber safety caps for each port on the port
module you are removing that uses an optical interface.

2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis. For more information
about ESD, see “Preventing Electrostatic Discharge Damage” on page 16.

3. Label the cables connected to each port on the port module so that you can later

reconnect the cables to the correct ports.

4. Use one of the following methods to take the port module offline:

■

Insert a pointed tool into the ONLINE pinhole on the front panel of the port
module to press the button behind it. Hold the button down until the OK/FAIL
LED goes off.

■ Issue the following CLI command:

user@host>request chassis fpc-slot slot-number pic-slot slot-number offline

For more information about the command, see the JUNOS System Basics and
Services Command Reference.

5. Disconnect the cables from the port module. If the port module uses fiber-optic

cable, immediately cover each transceiver and the end of each cable with a
rubber safety cap. Arrange the disconnected cables in the cable management
system to prevent the cables from developing stress points.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a
transceiver emit laser light that can damage your eyes.

12 ■ Replacing Flex IOCs and Port Modules

g030273

Replacing Flex IOCs and Port Modules

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems
that are difficult to diagnose.

6. Loosen the captive screws that retain the port module in its slot in the flex IOC.

7. Grasp the captive screws and slide the port module straight out of the flex IOC

halfway.

8. Place one hand around the front of the port module and the other hand under

it to support it. Slide the port module completely out of the flex IOC, and place
it on the antistatic mat or in the electrostatic bag.

Figure 8: Removing a Port Module

9. If you are not reinstalling a port module into the empty slot within a short time,

install a blank panel over the slot to maintain proper airflow in the card cage.

CAUTION: After removing a port module from the chassis, wait at least 30 seconds
before reinserting it, removing a port module from a different slot, or inserting a
port module into a different slot.

SRX 5600 and SRX 5800 Services Gateway Flex IOC and Port Module Installation Instructions

Installing a Port Module

To install a port module (see Figure 9 on page 14):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and

connect the strap to one of the ESD points on the chassis. For more information
about ESD, see “Preventing Electrostatic Discharge Damage” on page 16.

2. If you have not already done so, install the flex IOC in which you are installing

the port module, as described in “Installing a Flex IOC” on page 11.

3. Place the port module on an antistatic mat or remove it from its electrostatic

bag.

4. Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it

is not, cover the transceiver with a safety cap.

5. If necessary, remove the blank panel covering the slot in the flex IOC where you

are installing the port module.

6. Orient the port module so that the faceplate faces you.

7. Lift the port module into place and carefully align the sides of the port module

with the guides inside the flex IOC.

8. Slide the port module all the way into the flex IOC until it is fully seated.

9. Tighten both captive screws to secure the port module in the flex IOC.

Figure 9: Installing a Port Module

10. If the port module uses fiber-optic interfaces, remove the rubber safety cap from

each transceiver and cable.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a
transceiver emit laser light that can damage your eyes.

11. Insert the appropriate cables into the cable connector ports on each port module.

Secure the cables so that they are not supporting their own weight. Place excess
cable out of the way in a neatly coiled loop, using the cable management system.
Placing fasteners on a loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems
that are difficult to diagnose.

12. Use one of the following methods to take the port module online:

■

Insert a pointed tool into the ONLINE pinhole on the front panel of the port
module to press the button behind it. Hold the button down until the OK/FAIL
LED at the opposite end of the front panel lights green steadily, in about
5 seconds.

■ Issue the following CLI command:

user@host>request chassis fpc-slot slot-number pic-slot slot-number online

For more information about the command, see the JUNOS System Basics and
Services Command Reference.

CAUTION: After the OK/FAIL LED turns green, wait at least 30 seconds before
removing the port module again, removing a port module from a different slot, or
inserting a port module in a different slot.

You can also verify that the port module is functioning correctly by issuing the

show chassis fpc and show chassis fpc pic-status commands, as described in the

JUNOS System Basics and Services Command Reference.

Preventing Electrostatic Discharge Damage

Many services gateway hardware components are sensitive to damage from static
electricity. Some components can be impaired by voltages as low as 30 V. You can
easily generate potentially damaging static voltages whenever you handle plastic or
foam packing material or if you move components across plastic or carpets. Observe
the following guidelines to minimize the potential for electrostatic discharge (ESD)
damage, which can cause intermittent or complete component failures:

■ Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact

with your skin.

CAUTION: For safety, periodically check the resistance value of the ESD strap. The
measurement should be in the range of 1 to 10 Mohms.

■ When handling any component that has been removed from the chassis, verify

that the equipment end of your ESD strap is attached to one of the ESD points
on the chassis, which are shown in Figure 11 on page 17 and Figure 12 on page

18.

■ Avoid contact between the component and your clothing. ESD voltages emitted

from clothing can still damage components.

■ When removing or installing a component, always place it component-side up

on an antistatic surface, in an antistatic card rack, or into an electrostatic bag
(see Figure 10 on page 16). If you are returning a component, place it into an
electrostatic bag before packing it.
