Juniper SRX 5800 Instruction Manual

Replacing an SRX5800 Services Gateway SCB
Before replacing an SCB, read the guidelines in Operating and Positioning the
SRX5800 Services Gateway SCB Ejectors. To replace an SCB, perform the following
procedures:
1. Removing an SRX5800 Services Gateway SCB on page 1
2. Installing an SRX5800 Services Gateway SCB on page 2
Removing an SRX5800 Services Gateway SCB
To remove an SCB (see Figure 1):
NOTE: The SCB and Routing Engine are removed as a unit. You can also remove the
Routing Engine separately.
CAUTION: Before removing an SCB, ensure that you know how to operate the ejector
handles properly to avoid damage to the equipment.
1. Power off the device.
2. Place an electrostatic bag or antistatic mat on a flat, stable surface.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to one of the ESD points on the chassis.
4. Rotate the ejector handles simultaneously counterclockwise to unseat the SCB.
5. Grasp the ejector handles and slide the SCB about halfway out of the chassis.
6. Place one hand underneath the SCB to support it and slide it completely out of
the chassis.
7. Place the SCB on the antistatic mat.
8. If you are not replacing the SCB now, install a blank panel over the empty slot.

To install an SCB (see Figure 2):
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.
2. Power-off the services gateway.
3. Carefully align the sides of the SCB with the guides inside the chassis.
4. Slide the SCB into the chassis until you feel resistance, carefully ensuring that it
is correctly aligned.
5. Grasp both ejector handles and rotate them simultaneously clockwise until the
SCB is fully seated.
6. Place the ejector handles in the proper position, vertically and toward the center
of the board.
7. Power-on the services gateway. The OK LED on the power supply faceplate should
blink, then light steadily.
8. To verify that the SCB is functioning normally, check the LEDs on its faceplate.
The green OK/FAIL LED should light steadily a few minutes after the SCB is
installed. If the OK/FAIL LED is red, remove and install the SCB again. If the

OK/FAIL LED still lights steadily, the SCB is not functioning properly. Contact
your customer support representative.
