Release Notes for the BayStack 10 Power Supply Unit
Introduction
These release notes for the Nortel Networks* BayStack 10 Power Supply Unit*
provide information about software and operational issues not included in the
guides for the BayStack 10 Power Supply Unit.
These release notes cover the following topics:
•“Nonavailability in Japan,” next
•“Additional labels on rear panel of UPS” on page 4
•“Known issues” on page 4
•“Related publications” on page 5
•“How to get help” on page 6
Nonavailability in Japan
Currently, the RPSU portion of the BayStack 10 PSU is available in the Japanese
market. However, Nortel Networks does not support the uninterruptible power
supply (UPS) portion of the BayStack 10 PSU for the Japanese market. The UPS
portion consists of the following products, which are not available in Japan:
• UPS Controller module
• Battery pack
Warning: Do not change the MAC address of the BayStack 10 PSU
using the Console Interface (CI) menus or using SNMP. If you do change
the MAC address, it will no longer match the MAC address on the back of
the BayStack 10 PSU itself.

Known issues
The following are the known issues with the BayStack 10 PSU chassis, the RPS
SNMP controller module, and the power supply modules:
•If you disable an individual 136-watt power supply module in the BayStack
10 PSU using SNMP, the System LED for that module on the front of the
chassis turns off and an rpsuHubPwrFail trap is sent to the management
station.
However, the Nortel hub, switch, or router connected to the BayStack 10 PSU
continues to function normally using AC power, despite LED and trap
indications.
•When using the CI menus, start entering data at the default cursor position.
Do not use the arrow key to backspace into the fields preceding the default
cursor position, or you may overwrite the default data field.

The workaround is to press the [Enter] key repeatedly, until the screen
displays the following line:
---------------------------------------
(M)odify any of this or (C)ontinue? [M]
At that point, press m and begin modifying the necessary data again at the
default cursor position.
•The factory defaults have been amended in the following manner:
—The default TFTP IP address is now 10.10.10.10.
—The System name, contact, and location fields are blank.
•When the battery needs to be replaced, the BL LED on the front of the
BS10PSU lights. You can hot-swap the battery module. However, to reset the
BL LED, you must power-cycle the BS10PSU.
•When the AC power goes off and the battery is discharged, the BL LED
(battery low) correctly lights, but no SNMP trap is generated.
•When the AC power goes off, the BU LED (battery undervoltage) correctly
lights, but no SNMP trap is generated.
•When you are operating with the 200 W power supply module, you will not
see an SNMP trap for this module when you power-up.
•When you switch the power to the UPS unit, the SNMP agent may send an
err200UPSCommFail trap. You can disregard this error; the BS10PSU is
operating normally.
