Installing a PIM
To install a PIM:
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to the
ESD point on the device.
2. If the device is powered on, switch off the power switch on the back of the
device. Verify that the POWER LED is off.
3. Grasp the handles on each side of the PIM faceplate. On some PIMs the handles
are metal ears attached to the PIM faceplate. Other PIMs have long screws that
serve as the handles.
4. Align the edges of the PIM circuit board with the guide rails at each side of the
PIM slot.
5. Slide the PIM in until it seats firmly in the device.
6. Tighten the screws on each side of the PIM faceplate:
„ On PIMs with metal ear handles attached to the faceplate, tighten the
captive screws using a 1/8-inch flat-tip screwdriver.
„ On PIMs with long screws for handles, tighten the captive screws using a
number-2 phillips screwdriver.
7. Insert the appropriate cables into the cable connectors on the PIM.
8. If necessary, arrange the cables to prevent them from dislodging or developing
stress points:
„ Secure the cable so that it is not supporting its own weight as it hangs to
the floor.
„ Place excess cable out of the way in a neatly coiled loop.
„ Use fasteners to maintain the shape of cable loops.
9. Power on the device. Verify that the POWER LED lights steadily after you press
the power button.
10. Verify that the PIM status LED lights steadily green to confirm that the PIM is
online.
Upgrading Memory
You can upgrade an SSG 140 device that has 256 MB of memory to 512 MB by
replacing the 256 MB memory module with a 512 MB memory module. Ask your
Juniper reseller for kit SSG-100-MEM-512.
CAUTION:
Slide the PIM straight into the slot to avoid damaging the components
on the PIM.
