Symmetra LX/RM/XR Frames

At some point, a message similar to the following will appear, this page explains how to identify batteries:

  • Two column frames have Left and Right sides
  • Three column frames have Left, Center, and Right sides
  • Columns have either one, three, or five levels; top down

e.g. R2 would be in the Main Frame, right module, 2nd row.

Extended Run (XR):

The Main Frame is always designated as Frame #1. When Extended Run (XR) Frames are added, each frame’s number is set using the rotary dial switch on its rear panel communication card. The first Extended Run Frame is factory-set to Frame #2, with subsequent frames set sequentially to #3, #4, etc. Each additional XR frame is connected to the previously installed frame. Up to seven XR frames are supported.

ProblemPossible CauseSolution
Neither the rear green status LED, nor the front display illuminate after connecting the communication cable.There is no battery power present at the frame.Check cables and modules are properly installed.
The communication cable is not installed.Check the communication cable is properly installed.
The rear green status LED illuminates, but the front display does not show the frame number. The front display cable is not connected.See the Extended Run Cabinet Physical Installation Guide for proper cable connection instruction.
There is a potential hardware failure.Escalate to next support tier.
The front display continuously flashes on and off. More than one frame is set with the same frame number. Check XR frame numbers are unique (rear rotary dial).
An XR frame failure is reported. The front display flashes an error code. EO may indicate a missing/bad battery cable. Check that the battery cable is properly installed.
E7 may indicate a missing/bad communication cable. Check that the communication cable is properly installed.
Any other code could indicate a hardware failure. Escalate to next tier, and report the error code.
The front display alternately flashes the frame # and either Lx, Cx, or Rx. A failed battery module has been detected in the location shown.Replace the battery module with a known good one.
The number of reported battery modules is inaccurate. One or more battery disconnect switches open (LX only). Check that each battery switch is in the connected position. Use a coin to turn it.
Battery module(s) not correctly installed. Check that all battery modules are properly installed by reseating.
