Services Processing Cards

Services Processing Cards (SPCs) provide the processing power to run integrated

services such as firewall, IPsec and IDP (see Figure 1 on page 2). All traffic traversing

the services gateway is passed to an SPC to have services processing applied to it.

Traffic is intelligently distributed by SPCs to SPCs for service processing. Each SPC

is comprised of two or more Services Processing Units (SPUs).

The services gateway must have at least one SPC installed. You can install additional

SPCs to increase services processing throughput.

The services gateway has a total of 12 slots. You can install SPCs in any of the slots

numbered 0though 5on an SRX 5600 services gateway, and 0though 5, 2/6 , and

7though 11 on an SRX 5800 services gateway, top to bottom. The slots at the bottom

of the card cage numbered 0and 1are reserved for SCBs.

SPCs install in the front of the device (see Figure 2 on page 3).

If a slot is not occupied by a card, a blank panel must be installed to shield the empty

slot and to allow cooling air to circulate properly through the device.

Figure 1 on page 2 shows a typical SPC supported on the SRX 5800 and SRX 5600

services gateways.

SPC Components

Each SPC consists of the following components:

■SPC cover, which functions as a ground plane and a stiffener.

■Two Chassis Cluster Control ports for connecting multiple devices into a redundant

chassis cluster. Refer to the JUNOS Software Security Configuration Guide for more

information about connecting and configuring redundant chassis clusters.

■Fabric interfaces.

■Two Gigabit Ethernet interfaces that allow control information, route information,

and statistics to be sent between the Routing Engine and the CPU on the SPCs.

■Two interfaces from the SCBs that enable the boards to be powered on and

controlled.

■Physical SPC connectors.

■Midplane connectors and power circuitry.

■Processor subsystem, which includes a 1.2-GHz CPU, system controller, and

1 GB of SDRAM.

■LEDs on the faceplate indicate the SPC status (see Table 1 on page 3).

craft interface, see the SRX 5800 Services Gateway Hardware Guide or the SRX 5600

Services Gateway Hardware Guide.

Handling and Storing Cards

This section explains how to avoid damaging the cards (IOCs, SPCs, and host

subsystems) that you install into the services gateway. Many components on the

cards are fragile.

4■Handling and Storing Cards

SRX 5800 and SRX 5600 Services Gateway Services Processing Card Installation Instructions

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 5):

■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 types.

Figure 3: Card Edges

Holding a Card

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

Handling and Storing Cards ■5

Handling and Storing Cards

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.

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 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 6).

Figure 4: Do Not Grasp the Connector Edge

6■Handling and Storing Cards

SRX 5800 and SRX 5600 Services Gateway Services Processing Card 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 7).

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.

Handling and Storing Cards ■7

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 SPCs

SPCs are installed in the front of the services gateway. Before you remove or install

an SPC, you must power off the services gateway (see “Powering Off the Services

Gateway”on page 8). To replace an SPC, use the following procedures:

■Powering Off the Services Gateway on page 8

■Removing an SPC on page 8

■Installing an SPC on page 10

Powering Off the Services Gateway

Before installing or removing SPCs you must power off the services gateway::

1. On the external management device connected to the Routing Engine, issue the

request system halt operational mode command. The command shuts down the

Routing Engine cleanly, so its state information is preserved.

user@host> request system halt

Wait until a message appears on the console confirming that the operating system

has halted. For more information about the command, see the JUNOS System

Basics and Services Command Reference.

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 12.

3. On an AC-powered services gateway, switch the circuit breaker in the chassis

above each power supply to the off position (O). On a DC-powered services

gateway, switch the circuit breaker on each power supply faceplate to the off

position (OFF).

Removing an SPC

An SPC weighs up to 13.1 lb (5.9 kg). Be prepared to accept its full weight.

8■Replacing SPCs

SRX 5800 and SRX 5600 Services Gateway Services Processing Card Installation Instructions

To remove an SPC (see Figure 6 on page 10):

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

Also have ready rubber safety caps for each SPC 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 12.

3. If you have not already done so, power-off the device as described in “Powering

Off the Services Gateway”on page 8.

4. Label the cables connected to each port on the SPC so that you can later reconnect

the cables to the correct ports.

5. Disconnect the cables from the SPC. If the SPC 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.

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

SPC.

7. Grasp the handles and slide the SPC straight out of the card cage halfway.

8. Place one hand around the front of the SPC and the other hand under it to support

it. Slide the SPC completely out of the chassis, and place it on the antistatic mat

or in the electrostatic bag.

CAUTION: The weight of the SPC 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 SPC out of the chassis.

When the SPC is out of the chassis, do not hold it by the ejector handles, bus bars,

or edge connectors. They cannot support its weight.

Replacing SPCs ■9

Replacing SPCs

Do not stack SPCs 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.

9. If you are not reinstalling an SPC into the emptied slot within a short time, install

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

Figure 6: Removing an SPC

Installing an SPC

To install an SPC (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 12.

2. If you have not already done so, power off the device. See “Powering Off the

Services Gateway”on page 8.

3. Place the SPC on an antistatic mat or remove it from its electrostatic bag.

4. Identify the slot on the services gateway where it will be installed.

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

does not, cover the transceiver with a safety cap.

6. Orient the SPC so that the faceplate faces you.

7. Lift the SPC into place and carefully align the sides of the SPC with the guides

inside the card cage.

8. Slide the SPC all the way into the card cage until you feel resistance.

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

SPC is fully seated.

10. If the SPC uses fiber-optic cable, remove the rubber safety cap from each

transceiver and cable.
