The SRX340 and SRX345 services gateways allows
optional installation of a 100 GB serial advanced technology attachment
(SATA) solid-state drive (SSD), which can be used for storing traffic
log entries. The SATA SSD is not hot-swappable.
Note: Use only a Juniper-qualified SATA SSD.
Before you install the SSD, ensure that you have taken the necessary
precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).
- Power off the services gateway.
- Attach an ESD grounding strap to your bare wrist and connect
the strap to the ESD point on the chassis.
- Remove the two screws securing the SSD cover plate located
on the rear panel, and remove the SSD tray from the slot.
Figure 1: Removing the SSD Tray
- Place the SSD on the tray, with the label facing up. Secure
the SSD to the tray by using four M3x6 mm screws. Apply between 4.5
in.-lb (0.51 N-m) and 6 in.-lb (0.67 N-m) of torque to each screw.
Figure 2: Securing the
SSD to the SSD Tray
- Slide the SSD tray into the slot and secure the cover
plate.
Figure 3: Installing the SSD
- Power on the services gateway.
If the SSD is unformatted, the SSD is formatted during the bootup
process. A single partition in the Unix (UFS) format is created, which
occupies the entire SSD. The partition is mounted on the /var/ssd directory automatically. A symbolic link
(symlink) from the /mfs/var/traffic-log directory to the /var/ssd/traffic-log directory is created.
- Verify that the SSD information is displayed in the output
