ADDENDUM
This addendum in conjunction with the 
and the 
ESX-1320/ESX-1380 Local Management Guide
ESX-1320/ESX-1380 Installation Guide
 provides the 
documentation necessary to install and manage the ESX-1320R or the 
ESX-1380R Ethernet Workgroup Switch. This addendum documents the 
hardware differences between the ESX-1320/ESX-1380 and the 
ESX-1320R/ESX-1380R. Refer to the 
ESX-1320/ESX-1380 Installation Guide
for information concerning installation and troubleshooting. Refer to the 
ESX-1320/ESX-1380 Local Management Guide
 for information on accessing and 
using Local Management.
Overview
The ESX-1320R and the ESX-1380R are functionally the same as the ESX-1320 
and the ESX-1380, respectively, except the ESX-1320R and the ESX-1380R are 
equipped with redundant, load sharing power supplies. If one power supply fails, 
the other power supply continues to provide the power necessary to operate the 
unit. Two LEDs on the back of the unit (see Figure 1) indicate the operating 
status of the two power supplies. To accommodate the addition of the second 
internal power supply, the depths of the ESX-1320R and the ESX-1380R are 
greater than those or the ESX-1320 and the ESX-1380.
THIS UNIT HAS TWO POWER SUPPLY CORDS. DISCONNECT BOTH 
POWER SUPPLY CORDS BEFORE SERVICING TO AVOID ELECTRIC 
SHOCK.

Power Supply Operation
Power Supply Operation
The ESX-1320R and the ESX-1380R are equipped with two load sharing power 
supplies to provide redundancy. Two power cord outlets, labeled Power 1 and 
Power 2 (see Figure 1), are used to provide power to each power supply. To take 
advantage of the load sharing and redundancy capabilities, each power cord must 
be plugged into a dedicated ac outlet.
LANVIEW Diagnostic LEDs
In addition to the LANVIEW LEDs located on the front panel of the ESX-1320 
and the ESX-1380, the ESX-1320R and the ESX-1380R are equipped with two 
LANVIEW diagnostic LEDs located on the rear of the unit (see Figure 1). These 
LEDs provide an easy way to observe the status of the individual power supplies. 
Table 1 provides a description of the LANVIEW power supply LEDs.
