# iLO HP iLO, or integrated Lights Out, is a feature on HP servers that allows users to access the machine over the network even if the OS on the server cannot be reached. ## Accessing A server's iLO can be reached in two ways: * Via `ssh`, through `ssh server-ilo-hostname` * Via a web interface by visiting `https:\\server-ilo-hostname.csl.tjhsst.edu` while using a VPN ## Updating Firmware The version of iLO firmware that the servers ship with does not support access to the OS. The firmware can be updated with through the following steps: * [Retreive a copy of the most up-to-date-firmware](https://google.com/search?q=hp+ilo+5+firmware+update), download a `.exe` version for Windows * Unzip the executable with `unzip` or a similar command * Retrieve the `.bin` file from the unzipped executable * Access the iLO server you wish to update via the web interface * Go to `Firmware and OS Software` > `Update Firmware` * Select `Local file` and the `.bin` file you extracted earlier * Select `Flash`, this will update the firmware Flashing the iLO firmware *will* reboot the iLO, but will **NOT** reboot the server. ## Password Limitations HP has small password length password limits on iLOs. For HP iLO 5 (as of firmware version 1.35), it accepts any length password for a reset but only stores the first 39 characters (so you have to use the first 39 to login). HP ilO 2 has a similar problem, but with a 20 character limitation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
